What percentage do you charge your battery to?
Always 100% for that itchy throttle thumb.
To the top!
I probably should charge it less but I do 100%. I'm looking to buy a battery at a discount and do those blue batteries have the BMS? Maybe that's why they are way cheaper places like Alibaba. I saw a place where I could have bought the hammer bike for $750 if I waited three months. Well for people like me that will save me more than $600
I don't understand why it is not possible to have a generator on your bike to charge a battery but it must not be possible or someone would have done it. I've seen people make a house fan into a generator why could you not make a bike motor into a generator and have it in your wheel?
normally 100%. haven't had an issue with either of my bikes (radrunner w/ bolton upgraded controller and juiced scorpion with the off road controller upgrade). although, my scorpion does tend to "run low" on voltage faster than the battery loses power. maybe the 52v 13ah battery struggles to keep up with the off road controller power needs. not sure. doesn't really run the voltage low if i mix in some pedal assist.
This guy is one of the most realistic no bs about truth in ebikes
he misinformed. One should never fully discharge a led acid battery.
@@ohhenry5313 I accidentally fully discharged my 72v 50amp lithium battery, It used to charge to 85v now it only charges to 80v, the battery has only 500km on it, did I mess up the battery by fully discharging it to zero?
@@marshallmaia8130you just answered your own question lol
He is giving good advice, folks! I ride almost daily, going on five years now, on a heavy recumbent trike with the original battery. It has a 1kw Bafang motor and a 23 Ah battery. I keep it on the charger all the time. It takes hours to fully balance all the cells. I charge to 54 volts and rarely run it down past 47 volts. I take it apart yearly to check for corrosion and clean it up. The more oversized the battery you can carry, the longer it will last.
Does it need to stay on the charger for hours after the charger indicates it fully charged to balance? I always turn it off right after.
@@fritzstauff The Rad manual says 12 hours max.Read the manual as every manufacturer has different recommendations.
I spent close to 20 years in the lithium ion industry. This is a very good, informative post. There might be some minor technical issues but overall it is one of the best that I have seen. Simple and straightforward. Well done!
Shut up blair. I know you and you did NOT spend any time in that industry. Seriously come on!

Outstanding and informative tutorial on eBike lithium batteries. This is overall one of the best done videos I have watched on any subject, mixing practical and technical information in one very helpful package. Kudos.
Sir,you explained this perfectly, better than anybody else.....i needed the information for my 3 ebikes and 3 electric scooters....thank you
Tesla car company claims 1,000 times the recycle rate on li-ion if we charge to 80% and discharge to only 20% (above minimal rated safe voltage)
Throwing the battery into the snow.. all the antics.. made this well worth the watch!
Excellent information!
Charging to 100% is totally fine so long as you're going to use at least some % within 2 weeks at the most, but the sooner the better. I think for a majority of people, with modern lithium packs, degradation issues arise from improper storage far far more often than their charging practices. BMS have come a long way, as well as the cells. Basically just charge your battery, store it inside at a comfortable temperature when not in use, don't let it sit above 90% or below 10% for any prolonged period of time, and lastly maybe once a month to once every other month (depending on use) you should do a cell balancing charge where you leave the battery plugged into the charger for a period of time after it hits 100%. You better know how long to do this if your app or software gives diag info that shows individual cell voltages, otherwise you'll just have to leave it go for maybe 4-12 hours. Most chargers/BMS even once they show 100% do not actually stop charging completely. They typically drop to a very low current output, sort of like a trickle charge, and the BMS begins to very slowly balance out the cells in your pack. If you notice you don't get as much range from a 100% charge as you used to, cell imbalance is often the culprit. Although, depending on age and your care of the pack, it could just be degradation. However, even if your pack has started to degrade, if you have never done a balancing charge, you likely can get some range back from giving it a good balance charging.
Very well said! I had to copy for my eBike battery spread sheet
Day after day alone on a hill the man with a flat battery keeping perfectly still, know one wants to help him they say he's just a fool with his wheels not going round and the sun going down eyes in his head sees his. Day after days (fool on the hill )great video confirms what I was told and incidental how important care off batterys I'm 68yr old pensioner running with top down cannot afford the money to join. Information spot on 👍👍🌞
Thank you very much. Senior I want a e bike . Maintenance is the most important thing.😊 I learned something .
When in use i do a full charge. Just before i store it in the winter after a full charge i run it down to about 3/4 charge, then i pull the battery out and bring it in the house for the winter. Thanks for the video.
Cold is bad for charging if below zero, but it extends the life of storing longer term. Hotter reduces life when using.
The advice for charging 100 then discharge for longer term storage is right on the mark!
Thanks for the video . When I was looking at batteries for my travel trailer I did a lot of research that agrees with everything you said. I have always charged mine to 100% so I don't run short on rides and have not noticed any problem after nearly 4 yrs. Keep up the good work Kyle.
same here.. ive had mine nearly four years and I charge it daily..
@@europanzz it also has a huge impact on the lifetime how empty you drive the battery please do not drive below 20%.
Never ever only charge to 80 or 90%, such advice is actually killing battery packs. Always charge until after the light turns green for cell balancing. An unbalanced pack will die significantly quicker than it will take to run through the cell cycles
Thank you for teaching us what none of Amazon's eBike books discuss.
Thank You Kyle. You always put out great stuff.
A very informative video, and BTW, I love your shop! I owned or ran European car chops for 30 years. They were always kept clean. The customers like seeing it, you can find what your looking for, (10m socket) and it’s much safer. You obviously think the same way.
Thanks, 'Kyle and the Gang', for another awesome video! Your tips are always informative, helpful and trusted. Keep up the good work! Looking forward to the Juiced controller upgrade.....!!!! Patiently, that is. Thank you.
Thanks for the great info! I can't wait for my bike to ship.
This was extremely helpful and informative! Thanks!
Thanks, Kyle. That was both informative and helpful.
I certainly agree, big thank you.
Glad I already put this out on my channel months ago. Even did a follow up video for all my subs.
Per battery engineer discussion I keep my Li E-Bike battery between 20-80% for *longivity (charge cycles). I use a plug in timer (used for lights & sprinklers). It charges at 10%/40 mins. If it is at 60% I set timer for 2 hrs. I charge it to 100% once to twice a month & for the occasional 40 mile ride. *A new battery is %600.
Amazing!!! I bought a "RINKMO 350W Electric Mountain Bike", super fast and very cheap...
Thank you for the video. Blessings in your days.
Gotta love finding this as I approach the 21 month mark of running a 250 watt motor ebike from Nakto. To say the least the battery has been cutting out as it gets down to under 40 degrees here in South Central Wisconsin. I went from around 12-24 miles a day for the first 2 months of owning the ebike to around 2-8 miles a day for the last 15 months. It's one of Nakto's Camel bikes. Sort of crappy low end, ya ask me. But... For under $800, what can we say? Good video on the matter. Just wish it helped with the low end stuff I have. Ya know the 3 LED indicator set up kind? Yeah... They suck to no end...
Awesome, thanks for the great info by keeping it simple!!!👌🏼
Thanks for the excellent E-Bike battery tutorial.... just what l needed.
Yep, that agrees with everything I've ever read/researched about batteries....
Summer, winter I store my batteries (2 bikes) inside my back door (where I have kind of a little "charging station" for them). Batteries don't like wild swings in temperature I've been told.
Having the batts inside is also a theft deterrent for me as I keep my bikes outside, locked up on a covered deck.
One topic that was not covered is HEAT!...All batteries are black. On one occasion I parked in bright sunshine on a very hot day and the battery got so hot after a couple of hours I could barely touch it!!!
That can't be good. I now pay attention to where/what direction I park on such days.
I painted one battery white (to match the white bike...and tell them apart). Heat caused by direct sun exposure would be less of a problem with that one.
good tips in general too. this works for all lithium ion battery devices.
You answered so many questions for me, thank you!
An absolutely awesome channel that is teaching me so much! Thank you and for all that you do
Thank you. Sound information and very clearly explained
Amazing timing!! Looking at electric assist cargo bikes. You answered all my questions. Bravo! :O
If you fly radio controlled, li-ion powered airplanes and helicopters, you quickly become an expert on lithium based batteries, or you go broke. Charging from 80% to 100% creates a lot more wear than charging from 20% to 80%, and you should always store your batteries in a temperature controlled environment, at about 50%. With no load on the battery, that's about 3.85 volts per parallel cell pack. A 48 volt battery has 13 parallel packs of cells in series, so, for that battery, the unloaded storage voltage would be 3.85 volts X 13 = 50 volts. You should never leave a battery at 100% for more than a few hours, at most, and you should also try to avoid discharging below 20%. By the way, the 80%/20% rule works well for cell phones. I charge mine to 70%, and recharge it at 30%. So far, my phone has been charged in this manner over 1,300 times, with no loss of battery capacity whatsoever. Li-ion battery cycles are not linear. Charging from 0% to 100% equals one cycle, but charging from 30% to 70% (a 40% charge) is only equal to about one tenth of a cycle - not four tenths. A 20% to 80% charge is equal to less than a quarter of a cycle. New electric bike batteries cost hundreds of dollars. It's your money.
Great information.Thanks for sharing your insight of battery care.
Great information in a world of many options when it comes to batteries..... Thanks!
Glad it was helpful!
Nice vid, Kyle. Definitely worth re-watching periodically to remind yourself of what not to do.
Thanks you seem very knowledgeable! I have 3 e-bike
#1 IZIP,
#2 GIANT La free,
#3 Trek Alant 7S
The izip died with bad control panel rubber boot cover dry roted. I have be in electronics since 1966 HAWK MISSILES repair ect.. The IZIP was out of warranty plus the same week THEY WERE SOLD to another corporation. I diagnosis the problem and replaced the Capacitor that had blown apart. But that did not happen for a few months. Finally got the factory to sell me a new control panel for $300 +.. After a few more months!
They were supposed to send software to update . But was not delivered. More months. I had bought the new GIANT. Never got the IZIP to show any signs of life. It was a great bike before. I suspect the battery had died. Now I started my ELECTRONIC career with TUBES! My first computer class was programing CARD PUNCH.
JUMP STARTING 6 VOLT CHEVROLETS!! LOL LITHIUM IS SCARY!? I have Ischemic heart disease from US ARMY and Agent ORANGE 🍊. I ride my e bike almost every day. Would love to share the IZIP with friends. But here is the big question? How could I JUMPER FROM my know good GIANT or Trek. None of them are interchangeable. I would gladly BUY FROM YOU a new izip battery if I knew it would fix it ! Sorry for taking so much of your time . Paul Martin Hoover Al..

Great tips! And something else to always keep in mind if you're ebiking is to wear an nta helmet like xnito or bern, instead of a normal bike helmet (CPSC)
Why?
Great information, thank you!
Great video. Thanks!
thanks e bike guy im gana save this video for mine to make sure im doing it right
Excellent informative presentation. Thank you.
Thanks Kyle. Abaout as dimple as it could be explained.
Great video thanks
This was better than I expected as far as I thought I was messing up bad charging it when it was still pretty full like half or quarter to make sure I can make it to work and back with all the weight I carry with me but maybe I was thinking lead acid with the battery memory I hate all these things that a gas engine will just not have like that or the cold weather granted you may have a hard time starting it sometimes but once it does it will warm up. No half ranges and power loss it gets to be like eeehhh idk if it’s really worth what they charge for these things when there’s so many touchy issues with them.
Very informative video thanks !
I am impressed. Very clear, succinct and knowledgeable presentation. I definitely 'subscribed.
The "sponsor of the video" was funny lol awesome videos! Lots of into and entertaining. Good editing! Keep it up!
Thank you 🙏 for your wonderful knowledge you are wonderful
Interesting conversation on the Lithium battery discharge. I'll have to go back to my research but it seem Lithium batteries for an RV (solar power) vs AGM is the fact (or not) that you can only discharge an AGM to around 50% where as a lithium you can discharge to nearly Zero ?
Lead-acid batteries can be damaged by repeated deep discharge (more than 50%). Lithium batteries can normally be discharged to their full rated capacity (100%). Which means twice at much power. Note that this only applies to a drop-in replacement batteries that have an onboard BMS that stops discharge before the lithium battery is low enough to cause problems.
great info, thanks!
A dedicated bike fanatic who owned a Yeti Goal Zero Lithium Battery Pack mentioned that Lithium units should never be taken down to 20%. Was hoping this CZcams would have addressed a critical low threshold. Great presentation otherwise. Wonderful to learn Battery Love.
The critical low threshold is wherever the BMS cuts off the voltage (around 3-5% of capacity). I think it's just a general rule of thumb to maximize battery life to keep the charge between 20-80%. But from personal experience with various Li-Ion powered devices, the gain in longevity does not really justify the added inconvenience of always checking you stay within that range.
Check out some videos on super-charging electric cars, and you'll see that the highest charge the batteries can take is usually when the battery has between 5-20% state of charge (SoC). Those owners routinely let the SoC drop to 10%, then charge to 80% to minimize the charging time on long distance trips.
Good show, thanks
I got a heart thanks that's great do you need my add,
I am try to win a hat some day. Lol
Always top notch content.
I need that 52V 30Ah triangle battery, in stock soon I hope!
I found a 52v 20ah that looks better all things considered
Hi, I wanna say with balancing of batteries yes leaving it plugged in can work if your battery isn’t much out of balance and only slightly. however if pack is more out of balance this may not be enough. BMS may keep protecting those lower cells too much. What you can do is discharge battery not till flat but very low then switch it off and pedal home. Once reaches green unplug it, wait several hours for the resting voltage of all the cells to be reached, like overnight, then plug it back in in the morning.. charger should kick in again if it’s out of balance because those weaker cells would dragged battery down a bit reaching that resting voltage across the whole pack. If only charged for a few minutes more, unplug it again, wait even longer, give it a complete day then plug it back in. If it keeps only charging very briefly like less then 30 mins then either cells aren’t as out of balance as suspected or there is possibly damage.
20-80% is a great range to maximize battery life. Start charging no less then 20% so don’t try to deplete it below 20% and charge up to 80% you can extend charge cycle life from several hundred to several thousand possibly 10s of thousands of charge cycles if you stick to that. Alternatively 35/100 rule I heard.. don’t discharge below 35% but charge up to 100% that will also work really well at keeps my battery running a long time.
Kyle, I would love to see a video about lacing a Bafang H500 or similar hub motor into a fat bike rim. I love your open swapping out the internals and you have a great series on building a fat bike from scratch. But, I would love to see you explain and build the driving part of an Ebike!
I have 2 hubs I really want to lace into 19” moto rims there is one video I’ve found of a young guy doing it but without the hub motors I’m interested in more content on this also!
I have a fat bike and mid drive is really what you want to put on it. I got a 120mm 1000w bafang mid drive with a 52v 20a triangle battery 🔋. I've gotten it over 40 mph 🥴
I've been riding an electric snowbike, a Ruffian SEND-E for a bit over a month now. I store it in my shop, which is around 60 degrees. When I go for a ride, my thought is that the battery produces a bit of heat when discharging, so I don't insulate it or have heaters. After a ride and back in the shop, I wait a few hours before charging, and then I charge at a low rate, 2 amps. It's a 72 V/75 AH Samsung battery, and this procedure is working well for me as it has massive range, a 2, 2.5 hr ride usually shows it with 50% or more capacity left. What I DON"T do, is leave it out all night, though if forced to I wouldn't expect it to be a problem..
Damn you're the battery Guru I definitely subscribed and like
Excellent video!
Excellent video, Thanks ! ... Liked/Subscribed.
Your content is spot on and very informative. Thank you! The fluff was distracting....
Seriously, all these extra clips make it really difficult to follow the video. One or two = funny, more than that = annoying.
Especially on top of several ads.
I agree. Adding that many ads is ridiculous.
yep, valid point!
Yup, too cute by half. I clicked for knowledge not comedy.
@@skepticsr_us Yes. Far too many ads on this clip. Fucking Google!!!
Thank you. correction for balancing you also need is to discharge the battery enough so the BMS has chance to do its job properly. Only charging fully will not make the trick because the BMS will disconnect when it reached its max voltage regardless of each cell actual voltage.
Max charger voltage typically == 4.2 volts per cell group times the number of cell groups in series. So no cell group will be below its max 4.2v, unless the BMS is broken and has allowed overcharging one of the cell groups to > 4.2v.
I had my 15ah 48v battery since 2013 & put 22k miles so far I use it to commute to & from work 14 miles round trip so it’s never gone below 50% died on me one time in the summer heat riding hard for a couple hrs but still going daily
this video could have been 5 minutes long with all the same info but I did find it helpful so thanks.
Finding your videos full of useful information. One question, do you make or sell a "lipo" bag for storage and charging? i find myself a little paranoid about the possible dangers of e bike batteries. Thanks!
Any benefit to using a type of trickle charger on the battery?
I sort of accidentally came across your channel and I'm glad I did. I was looking on your ebike site and I was looking into getting two e-bikes so that my wife can join me on rides. I am getting the bikes as a means to maintain my health as well as to maintain my weight loss. As of a few years ago I was once at my heaviest at 620lbs and a few years later I am currently 324lbs and my weight has stabilized. I would have got your bikes sooner it just I got laid off last year and I was recently recalled back to work and I'm saving so I could place the order
I'm happy you found it! Keep watching! So much more fun to come
Wow!!! Congrats on that weight loss!!!!! It takes a real commitment to do that. Wishing you the best👍👍
@@1packatak thank you
In cold weather, you can adhere a small 7w polyimide heater on Garolite and place it under the battery. You will need to add a resistor to lower the temperature to ambient.
It would be good to keep a record of your battery's mileage and charging cycles, get a $10 voltmeter and learn its charging curve. Charge it to 80% 4 times then a full charge once, then repeat. The meter is useful all around the shop anyway.
In winter, check it and keep it at 70% and you're golden.
I agree. And trickle charge as much as possible. Never get hot.or run low.
Thanks for the info, what voltage do you charge it to ,the 48 volt or the fully charged voltage 54.4 volts to store it at 70%.
@@herbboughner3944 54.4 is full, if it took 6 hours to get there, give it 20% less time on charge and read the voltage for yourself. I give mine 4.8 hours on charge and call it 80%. It isn't a critical measurement, and different batteries will have different curves due to age, actual usage and charger output.
Great Info.! When charging is it best to charge just before a ride...esp. if charging to 100%?
Great, Thanks !
I just bought a Cycle Satiator for my hyper scorpion and my yamee fat bear, was wondering have you ever made a video on that charger, I know youve talked about using them b4
Great vid, thanks, and well done!
I have questions about my battery gauge. I have the 8H color monitor. I like it pretty much, but I don’t understand why the green bar graph doesn’t seem to indicate battery usage properly. I’m also curious about the volt indicator. If full is 54 and 40 is empty (for all practical purposes) does than mean that 47 is half full? Like, if I went 20 miles and is says 47, should I be able to repeat that route?
Hey, does Bolton repair Bafang ultra mid drive motors? If so, do I just call and schedule with you guys? If not do you have any suggestions where I could get it repaired? ( I live in New York) THANK YOU! and I appreciate this video! You’re always giving out great info!
@Kyle - should you leave the battery charger plugged into the battery after it reaches 100% charged or unplug the charger?
My bike says the first 3 charges leave it on as close to 12 hrs as you can no matter if its fully charged or not
But after that you def wanna take it off charger
I have 6 pcs identical 36v 21ah unprotected packs (li-ion) - none has any bms attached yet....My plan is to use all 6 packs as one (36V 126AH) with a single bms...do you think its a wise idea considering the fact that maybe balancing would suffer?....or should i put a bms in each pack and then parallel them with y-xt60 joiners? Its a huge pack that will be placed in my tricycle...I REALLY dont want to break the packs up...that would be a total nightmare... Thanks dude your videos helped me alot=)
Summary: Just use it. No Maintenance necessary. Don't freeze them.
Dude - - You ave come a looooong way !!!! Dang how many batteries could You have ?? Inventory at $ 1 million yet ??
I got over like 20 thousand miles on my bike same battery works perfect
That is quite impressive. Are you using Li-Ion or LiFePO4 or something else?
Can you describe how you use your battery? Do you charge it to Maximum voltage after every ride, 1x per week, etc. or do you charge it to a slightly lower voltage to prolong battery life?
e.g. daily commute of X miles/km, weekly trips of X miles/km, occasional trip of X miles/km, infrequent trips, etc. Thanks.
Can you tell me what battery and controller and motor you are running? And what range is max for your set up? Thanks so much 🙏
Sounds like some BS to me lol. But if so then very cool
@@keithmo80 its called a ecotric bike
I believe you it's still working perfectly fine, But I bet you ain't getting close to it's original range! A battery pack can continue doing it's thing for as long as the cells can hold a charge, But the efficiency will diminish during that time which also means your range.
The battery explosion shown in this video is a Lithium Polymer pouch cell battery that's been seriously overcharged.
Those are used primarily for drones, and RC cars and boats.
Some do use them for ebikes because of the high C rating but without the proper balance charger, they can become firebombs.
Wow i learn a lot I have a D-Class ebike do you know where can I get an extra battery or one that last longer?
Enjoy your videos, very informative with alot of information. I am having a hard time finding an ebike that fits what i need. For my situation its folding, 750w motor, prefer hub motor, and integrated lights as I would need to ride it on a busy street so brake lights are important, oh and fat tires because often would hit dirth/gravel paths. If anyone has recommendations I would appreciate help. Gforce has the t42 but a few things concern me with them, like replacement parts are mailed from China, so if any issue arises i am stuck without a bike.
Hi I have a swagtron eb7 bike I need to change DC port socket on the bike I was wondering if you had any videos on that
