A while back, I had a lil baby 3s pack pop after a charger (the blue unit shown here) finished the crest of charging cycle. Blew the a$$ clean outta the "lipo safe bag" in about 5 seconds, then the fancy linoleum floorboards shortly after. Filled the house with smoke in 15 seconds, which is howong it took me to get them outside. Took 2.5 hours for the fully-opened house to clear the smoke. That was a tiny lil 300mah unit. Imagine an unattended 5000 4s? I use a tin now with cables grommetted through the side. It doesn't seal. Good so far. Two ways to learn, I guess. Thanks for the vid.
If u do ion. Watch ICR. INR etc. Are safer. PEACE. BE SAFE
Nice! I never knew the battery rocket possibility...I will be investing in a cinder block for my workbench now.... Thank you!
Thumbs up. I always (balance-) charge with 1C. But didn’t know that not fully charging the battery would matter much. Quite handy with crawlers. But with buggies and speed runs, full voltage is important.
John you might want to talk about how to safely dispose of puffy packs.
I think you're supposed to poke a hole with a fork like a tv dinner to relieve any internal pressure. I'd love to hear John's thoughts, though.
Discharge in a cup of salt water , once they are dead there is no danger
The only one I ever had puff,I just took it in the back yard and wacked it with a shovel. Nice little fire show then threw the remains away
Nice video easy understand I use lipo bag inside an old fireproof box with hole cut out with it locked to store and charge battery
I still have a working ni-cad pack from the early 90's (and shocker, it still has nearly full capacity). But otherwise, I'm fully lipo. I had one lipo that fully discharged down to no volts - I got rid of it safely. My other lipo packs have held up quite well. I had a nickle metal hydride battery for my T-maxx 3.3 starter, but that didn't hold up very well (at all). My charger is an old SkyRC IMAX (store branded, & undoubtedly just a clone) B6 charger - works well.
I've got two 6v ni-cad packs for my Tyco Rebound that have been going strong since I got it as a kid in 1996... They haven't lost much of their capacity, it would run for about 15 mins on a full charge when it was brand new, and it still runs for about 15 mins on a full charge 26 years later. I charge it up and take it for rip around the basement a couple times a month
i really love the spectrum especially the g2’s. more expensive but seem to be incredibly safe/easy
Very helpful and educational video. Thank you, John!
Great video thanks again
I'm still about 50 50 in terms of what I own for NIMH and lipo, I love lipos but I don't like to have to babysit them for storage charge and things like that
I throw 45A into my 2S pack, for ROAR races.... sometimes 55A! Also discharge at 100A. 401 Duo charger, by i charger
Great if you're a racer and have money to burn but not practical for your average hobbyist 👍
I use a Hobbymate D6 Duo AC/DC (same exact menu as your ISDT but different colors) on ovonic 5500 50C 3s Lipos for my Arrma Big Rock. While i could possibly charge at 2c (11 amps) i choose to charge at 1c, takes about an hour from storageand doesn't get hit. While i don't cover the batteries i never charge without being present and constantly monitoring. I feel the pack every so often feeling for swelling, so the moment i feel it, out it goes
I have a question I seen this video and seen that you had the xt plug as well the white plug do you need to have both plugs in when charging a battery
The white plug is the jst connector, used to balance the battery pack while charging. As John mentioned, you should always balance charge your packs so, yes, you need both plugged in. That being said, if you do decide to do a fast charge than the jst/balance plug does not need to be plugged in 👍
John we need a Holmes hobby scx24 motor and esc comb it would be really nice and sell like hot cakes 😜
I use lipos to weld 18650s. Only lithium batteries I keep in outside shed where I do my assembly. I also have icr ion. I watch close my INR are powerful and safe. LEARN ALL YOU CAN FELLAS. REMEMBER. THE AMPS KEEP VOLTAGE. UP. LINEBACKERS. VOLTAGE EQUALS SPEED. WIDE RECIEVER. WATTS. IS. VOLTS X AMPS. =. THE TEAM
Maybe cover safety on storage charging?
I use a old computer power supply to power my twenty yr old Duratrax Intellepeak Ice charger. I charge my gens ace 4300 s at 4. amps so they never get hot.. To ballance them , I use whats called an Astro Blinky, its just not built into the charger.. John, have you ever heard of these two products ?? They still work great,and as I"m just getting back into the hobby , I"m not ready to pop for new stuff!! This charger came out around same time as LIPOs ?? It still is like new man,and for now I can crawl for two and half hours on each 4300 Gens Ace lipo!!
For sure, I used to have some blinkies!
Lol 90% Lipo and one that I keep original with nicad! From the 90’s
Interesting. I didn't know that going a bit less than a full charge helps increase battery life., though I figured that reducing the charge rate does. I just got a fancier charger that lets me easily control that.
And, yeah, a flaming rocket in my house would be bad.
Can you run a RC’s on storage mode battery? And what exactly is storage mode?
To update my last comment ,I just ran down stairs to look.. The reciept in the box says 2006 from hobby town in Omaha Neb..Bought when racing off and on road from my friend Alex Sturgeon, now manager of HobbyPlex in Omaha!!
The landfill caught on fire last year and they said it was started from a battery.
I'm going to let myself believe it was a galaxy note or a vape lol
Spektrum is getting more and more proprietary.
Hey John 🤙. I'm sorry, this is "a bit" off topic. I was just watching one of SBG's live stream takeovers from May 2020 that you were in. You said that the "cork" esc company got bought out by the South Korean military. Super curious, what the heck was the military using micro brushless speed controls for??
It was Quark. I'm not sure, likely drone use.
@@HolmesHobbies Thanks for the reply homie,.... Or would that be "Holmesie" 😅🤙. I guess drones would make sense.
Great review John. Been using 3800 nickles in my rigs for three years now with no issues with long run times. Can't see the advantage of Lipos. Is the weight of the Lipos the only advantage?
Weight, energy density, size
I like to charge at a lower rate. As you said charging at a lower rate makes your LIPO batteries last longer. I usually charge at 2 amps. Thoughts?
As long as it doesnt heat up much. Heat is usually the cause of bad battery cell
lipo charging made me feel like a noob in RC
I'm on nimh for now
Is it safe charging a lipo on a wooden table? lol/
Charge at 1 c and never have a lipo fire
Back in the Day...wow, my son laughed, my wife laughed, I laughed and threw my back out. Great, another few weeks out of action.
John does like to go off on his tangents, lol! 🤦♂️ Slow it down and keep it simple dude - just basic battery care and maintenance. I've been doing this 30 years and I have trouble following you sometimes (write yourself a script, maybe?) 😉 Hey, cover more advanced techniques or theories all you want but have a separate video for it. That being said, I think videos like these are really needed and have lots of great information for just about anyone to take away! Thanks, John! 👍
You don't want to see me read a script, unless you like completely dry emotionless videos. I make outlines and stick to the main points, none of this vid was tangents, lol!
@@johnrobholmes Then slow down man, a little TOO much emotion! 🙃
Nice simple breakdown of it all. Thanks man.
I have to admit I don't have much in the way of protection when charging the battery. Mainly cos the wires for the balance port are so short, there's no way I could put the battery in a bag let alone a box, concrete or whatever. I did use a terracotta pot over the top once which kinda worked. Flames would just shoot straight up the drain hole then haha
I don’t know what my problem is but every time I look at this guy I can’t take him seriously.
WHY NOT CHARGING FULLY IMPORTANT. 36v. Lithium ion ebike bottle battery. 50cells. I slipped when I first bought fully charging till light was green. But then. Was careful. $175 badass battery is 5 yrs and counting. I've bought LG cells MH at$1. Battery clearing house. Made New packs. GUYS DO DILLIGENT RESEARCH. COLLECT ANY ION CELL YOU SEE. WITHOUT STEALING. MADMAX BABY. PEACE!!!!!!
And 36 v ebikes are cheaper and more efficient than 48v
See: KingSong S20 meltdown
10amp hour originally. 20mph at 20 miles. Now age I still get almost 15. I'm shocked. DONT FULLY CHARGE. DUMMIES. VH forever!!!!!!!!
Hi Johnny Depp
Do you micro dose?
