Nice video again! looks like i'll be buying one of those eco worthy batteries really soon lol.
Thank you for your feedback its appreciated 😊
Офигенная батарея, тоже планирую взять себе такую для своей сэс для резерва и природы 🎉
I bought two of these together when there was an offer on (seems like they always have one on) for around £500ish. I can't believe how much they pack a punch over my lame AGM batteries. I benchmarked them with a 1kW electric heater on during December and it lasted exactly how you would calculate it for 100Ah (2 hours) @ 24v.
It's even more impressive thanks to your video at how modular they are. It seems like you can simply swap a cell out of its bad and even replace the BMS (which they tell you you can do in the instructions). I was skeptical at first but the quality seems quite good and the cost price over paying thousands for a brand name like Renogy etc.
Looks to be good quality. Re soldering, well I guess Lead Free these days - never flows as well. Re the connections, a nice big fillet all helps with keeping cool at high discharge rates, perhaps as you said a bit long but definitely safe though. Good to see the same sort of quality between batches. A good review and decent video, thanks fort doing it.
Thanks for watching and taking time to comment 🙏
Awesome video
Thanks!
Good job
Thank you for watching
I'm thinking of getting these or ampere time brand
Hey there big man. Thanks for stripping down these batteries for all to see. Very helpful indeed. I have 2 of these coming for an24v pack. do you think a Victron Battery Balancer between the 2 batteries is a good idea?
Hi, it wouldn't do any harm, always prudent to fully charge each battery individually and leave them to equalise overnight before making your final connections.
@@DCGUY Thanks, will do a full charge with a 12v battery charger before I series wire them.
I still have a Victron BatteryBalancer in the case from when it was a lead system. So will make use of it.
Hello how to remove the cover
Ordered one for 265 USD on eBay, great price for a LiFePO4!!
Wow, can't go wrong at that price. 👌
How is it holding up?
Excellent tear down thank you. I saw your review on the Eco worthy website. I use Renogy batteries for myself but I have just ordered two Ecoworthy 50ah batteries for a friend. On your video and from the battery spec sheet I cannot see a low temperature cut out to prevent harmful charging at temperatures below 0° C. What are your thoughts/ findings on this matter? Thanks, Kith.
Yes your absolutely correct, there are no details for charging / discharging Outwith the parameters The manufacturer only says -: 2.2.5 Standard charge temperature 25±2℃
2.2.6 Absolute charge temperature（Cell temperature）0 -60°C Stop charging once cell Temperature is outside this range regardless of the charging
mode adopted2.2.7 Absolute charge voltage 3.65V max.
Stop charging once voltage exceeds this voltage regardless of the charging mode.
Unless you want to open the battery and upgrade the BMS or use a separate temperature sensor as a visual I'd just keep the batteries in an insulated box / location.
@@DCGUY looks like K2 is the low temp connection point, Eco Worthy just didn't bother connecting it. I
Looks they now include cold weather cutoff.
Ya I bought one to power boat electronics it's half of name brand batteries an like the same build quality....or is there another battery you would recommend?
I can only make recommendations based upon my own experience with a product. There are some good inexpensive life4po batteries out there, eco worthy seems to have found a good balance between cost and quality. Just do your own research before buying.
not sure what purposes all that glue served, and I didn't see any high and low temp sensors that would shut the battery off, did it have them?
There was only high temperature sensor within the bms itself & yes lots of brittle glue.
Hi, I bought a 100 ah Eco Worthy battery and a Noco genius 10 for its lithium charging abilities, I charged the battery until I got a solid green light on the lithium setting and used my multimeter to check the voltage. I got a reading of 13.41 V, I noticed in your video after charging your battery was reading 13.96 V and the leaflet from Eco Worthy states 14.5 V max charge voltage, should I be concerned at the low number or is it that I have not yet discharged the battery before topping it off?
I wouldn't be concerned as lifepo4 battery absorption voltage isn't the same as lead acid voltage ( it get complicated and not enough room here to get into details) it can be confusing but just use the battery. Your charger is probably not truly lifepo4 friendly, most chargers claim to be but aren't and are set to cut off at a certain voltage designed at lead acid levels. Lifepo4 absorbs voltage differently to lead acid. Let the battery sit overnight after charging and take a voltage reading, you'll see a change in readings. If you can afford it, get a higher amp charger, I use the victron 30A which is configured for lifepo4 chemistry. Hope I haven't befuddled you, it is confusing for the best of us.
@@DCGUY Thanks for taking the time to respond, it makes sense for a primarily lead acid charger 10A output to struggle to hit the max level. I bought it specifically for its lithium setting, learning all the time.
Would a 2 bank charger work to charge them separately? Or would that somehow be an issue with the bms? Im thinking of a noco 2 bank 5amp, which is rated for standard battering/afm & lifepo4.
A 5 amp charger will take a long time to recharge a 100ah battery, as much as 20 hours for a fully depleted battery. It's recommended to use a minimum of 10amps, higher is faster up to the BMS limits. It is recommended to charge individually if you plan on making a parallel or series connection, then make the connections.
Can you tell me what brand the BMS is as I have tried to get this & more info out of Eco-Worthy but can't without an order number which I don't have?
They were using a jbd bms. There is a link to them in one of the videos descriptions. I upgraded to ones with Bluetooth.
Hi dc guy great video , can you tell me is the 30amps the maximum that can be input to that battery when being charged, and would the bms shut down if over ampage was more then that. The reason I ask is I'm using a renogy dc to dc 50amp charger in my van, and with 48amp going in to my kepworth battery from alternator it trip out my breaker going between the battery and the DC to DC charger. Breaker is a 60amp but doesn't reach the ampage. I can bring amps down with the dc to dc charger to run at 30 amp. Cheers
The eco worthy can be charged at a maximum of 50A and are you using one of the less expensive thermal breakers? If so the tend to throttle amps and in the process become hot and trip. Charging at 30amps is not an issue.
Sorry but it was regarding the kepworth 100ah lithium battery you did a breakdown on. I've posted on the wrong video and yes it's one of those thermal breaker I'm using. Cheers
I have tons of these. They always tested at least their capacity of 1280wh. The last 2 100ah I bought, I hooked them up in series and ran a capacity test and got over 2600wh. Great batteries for the price. I have tons of their solar panels too. While the panels efficiency/rating is not as good as others, their efficiency/price ratio is the best. What I mean is that their 100w panel might be only getting 75w on average, but it only cost $50. Other 100w panels might be getting 85w but they cost $70 making the Eco a better value. Their panels are also smaller in size.
Thanks for watching and taking time to comment, it is appreciated
Which lifepo4 battery would you recommend, 100ah min I’m looking for
Thanks for watching and taking time to comment. It's your own budget that will dictate, but I'd say buy the best you can. SOK have good reviews from others, renogy are good too but their after sales service is poor. Eco-worthy are OK ( I have 4 of those) Ultramax is OK but heavier than others. Kepworth do the job for a low cost. Do some research on what's available within your budget. Have you considered building your own battery? 4 cells and a BMS your in business!
Have you done the 50ah unit? I'm curious if the BMS is up to snuff.

Those darn left handed screwdrivers
🤣😅
Hello , I would like to know what brand and model of BMS has the battery. Thank
It's a jbd 12v 4s 100amp bms
Do these actually have low temp cut-off? The picture in their advertisement had "Low temp cut-off" printed on their battery, what they sent me did not have that and on the back said not to charge below 0C. I'm guessing they sent me an older or cheaper version?
The ones I have and tested do not have any low temperature protection, but they do have over temperature with the exception of their 50Ah battery, which has neither.
Hi, I bought a 100 ah Eco Worthy battery and it will drop to 12.8V very quick from full 14.4V / with only a 15w small tv
Has the battery been able to enter float/absorption stage while charging? Lithium SOC/Capacity is hard to gauge using voltages alone. Anything over 13v is essentially full charge. What you want to do is monitor actual Wh the battery supplies during use ideally using a shunt. That will let you know if you have got a good or bad battery more definitively
a question, a 25 sq mm cable about 30 cm long how much ampere absorption can it withstand?
I have 2 eco-worth 100 amps in the camper, respectively connected to a busbar via a 25 sq mm cable each, if I require more than 1500 watts the bms disconnect the load could it be the section of the cable is too small?
the absorption of the 1500 watts occurs through edecoa 2000watt/4000 watt peak
Thanks again
Are the batteries in Parallel or series? If in parallel the BMS is rated at 100Ampss so may not like anything over 125A continuous (1500W @ 12V = 125A) So your cable is rated at 125A max. The increased resistance wont aid so increasing cable size wont hurt especially if you plan to use in excess of 1500w for extended periods. A 2000W / 4000w inverter at 12V can pull anything from 166Amps to 333Amps, so again look at getting suitable gauge wire rated for your system and make sure you have a proper sized fuse between battery & inverter. If you have them in series, (24V) then that cable is ok so id suspect a bad BMS / battery assuming the inverter is ok.
@@DCGUY my batteries are in parallel each battery has 1 cable both negative and positive of 25mmq of 30 cm connected directly to the general negative busbar and to a positive busbar so could the intervention of the bms be attributable to the insufficient 25mmq cable?
@@DCGUY having the two batteries connected in parallel should I have an availability of 200 amps?
so about 2400 watts right?
2 x 12v 100ah batteries in parallel gives a 12v 200ah battery. E.g the length of time a battery lasts increases but voltage remains equal. Each battery has a 100amp bms, so the loads should be shared equally between batteries so you can max at 200a but it's not advisable. If you goto dcguy.co.uk on the downloads page look for wiring unlimited by Victron, it's a good starting point to make sure your getting things right.
@@DCGUY Thank you very much I'm going right away a good evening to you and I'm happy to follow you
Maybe I missed it but is there a cold temperature sensor on them
Hi, thanks for watching and taking time to comment 🙏 it's appreciated. They only have over temperature protection on the bms.
@@DCGUY Thanks bud.
Hello, Can I ask if your Eco-worthy batteries are still okay? I'm asking because I've just purchased 2 and 1 of them was badly swollen when I unpacked it, they have offered to replace it but I'm thinking about asking for a full refund. Also, the batteries don't have a date of manufacture or any serial numbers stamped on them which doesn't seem right.
Hi, thanks for taking time to comment. The date of cell manufacture is actually on the cells, not the battery case. To date my own 12V 100Ah eco-worthy batteries have been fine. When you say swollen, are you referring to the actual battery case or the cells? Either way there should not be any swelling. I bought mine before Fogstar started selling LifePO4 here in the UK. I have teardown of the Fogstar here czcams.com/video/lH-GX94D1sA/video.html and they are better quality than the eco-worthy and cost less. Depends where you are located. If your in the UK id go with the fogstar over eco-worthy now for simple value. If not, just get them to replace. Like i said, mine have behaved in my ownership time, maybe youve just been unlucky with one. Best Regards.
@@DCGUYHi, Yes, I'm in the UK, it's the outer case front and back sides that are bulging, do you think they may have started using pouch cells in the 100Ah now? I don't think Prismatic Cells would expand in this direction?
Without opening its anyone's guess. Prismatic can and do swell but play safe, while they aren't a direct fire hazard they do contain liquid electrolyte. If a cell has been compromised in some way the escaped gases could cause the case to swell. Check its voltage that may give a clue. If its 11v or less maybe a bad cell but voltage alone doesn't give overall health of the battery. Let me know how you get on, the feedback helps others.
@@DCGUY Hi, like you say it could be escaping gas that's causing the case to swell, the voltage is 13.3v, I have now requested a full refund for both batteries which shouldn't be an issue considering I've only had them 7 days, thanks for the advice and I will let you know how I get on.
Thanks for the review. According to Eco worthy one can connect 4 batteries for a larger battery bank. What happens if one connects more than 4? Say 6. Do you know?
What it says if I remember correctly is 4 in series and infinity in parallel , this means you can connect 6 but you need to have a set of series parallel connections , so for example , for your 24v system just do 3 pairs of series connected batteries (2 batteries per series string pair), then wire them all up in parallel and expand this way, that should satisfy the requirements of these batteries, this would more or less create a 7.6kwh system at 24v, I have 4 otw to my place soon , keen to try them and if all goes well I'll get another 2
In theory you can parallel connect a large string of batteries with the same voltage / Ah rating but when you exceed 4 in this case there are some risks due to the battery management systems ability to balance / charge each battery and overall voltage / amperage limits of each BMS. Also if a BMS were to fail or short it could potentially be a safety issue. There are people out there with large lifepo4 battery systems who place fuses between each battery as well as external balancing systems. The manufacturers are essentially limiting their liability by limiting the suggestion numbers. I've got 4 in parallel giving me 12v 400ah and so far no balance or charge issues. Admittedly if I had more I'd still keep to 4 in a bank for peace of mind. Its a great question thanks.
@@DCGUY ok, thanks for the quick response. I have a 12V system. Connected to two Epever MPPT 100A charge controllers, each connected to 1200W solar panels i.e. 2400 W total. I think it's easier to have them connected in one large bank, rather than many smaller banks. I have 6 batteries, but thinking of expanding by two more. I'll let you know if anything "bad" happens. Cheers
@@sia.b6184 ok thanks. But i have a 12V system. Forgot to mention that. I have 6 now, but will maybe expand with 2 more before inflation gets worse. Cheers
Hope it all works out well, please let me know how things go. Cheers 🍻
Are they safe to be but in Series and Parallel? Have you tried? Thank you
Hello & thank you for your support 🙏 irs really appreciated. They say you can have up to 4 in parallel 12v or series (48v). Any more risks over voltage disconnect on the bms. I'm also told they support a series/parallel connection but I've not tried that.
And I've been using mine in parallel, 12v 400ah with a 3500w inverter. only down side is cable sizing and fusing. I'm going to go 24v, perhaps 48v though at some point, just not sure on inverter choice yet.
@@DCGUY Thank you for the feedback. Id be wary going in series. Ive read alot of the reviews for these batteries including this model and although the companies say you can I see ppl with dead BMS's and blown mosfets frequently. Ideally id get a EG4 or Jackiper batt but they are a little more pricey and amperetime(sold out) and chins and zooms dont seem to make a 24volt 100amp. Ill keep searching Thanks again and good luck with the solar!
@@garyenwards1608 look into eco Tree batteries in the UK.
Ar you conserned about the balance as one is pretty fdar off?
No concerns there, passive balancing just takes a while but gets there.
FWIW.... AT 11:00 YOU CAN see it is a JBD bms and thATS why I watched the video... to see what bms eco worthy is using.... this is a good one.
Correct, JBD 12V 100A BMS. I upgraded the BMS to a new JBD with BT
Indeed...can you buy just the blue tooth plug in? so one does not have to buy an entirely new bms?
I have two 24vdc coming to make a 48vdc and now that I realize that lack of communication I should have coughed up the money for a server rack form the same company as my 24v will not have blue tooth. I was looking at the up grade you speak of but have to cut the batteries open... over sight on my part. I'll set it up and see how it goes. I dont trust any bms to balance with out the setting being changed. just my opinion. @@DCGUY
Assuming you are using eco worthy batteries, the BMS won't have a BT option on the board which means you would need to open and replace the BMS units. Probably not worth the effort for you to undertake the task. An Inexpensive shunt will aid you in keeping an eye on usage and voltages.
yes but wont let me balance the batteries... live and learn. this is brand new tech and I did not realize how new when I went down this road.@@DCGUY
@@DCGUYcan you do an explanation video of this? Using the 100ah for my trolling motor and look for possibilitys the see the remaning capacity/voltage
Hola gracias por el video .
Tengo una de 100 ah y se estropeo una celda .sabes donde la puedo comprar?
Aliexpress. Ganfeng cells.
@@DCGUY muchísimas gracias
Received one of these a few days ago direct from Eco worthy, and with a charge of only 9 volts. Customer service told me to try charging it which I have, but it won’t charge and now they won’t respond when I ask for a refund or replacement. Good when they work I guess! Started a claim through card purchasing company. Disappointed!
That is so frustrating, I hope you get some resolution to this. Keep at them.
Any resolution?
How did you open the battery?? Did you heat gun it
No heat gun required
What an absolute shame that in the UK we have second rate batteries. Why do we appear so far behind the US with this? Considering our climate I'm super surprised there is no low temp cut off or internal heating. What good uk manufacturers or suppliers do we have that actually put together a decent battery that would have these features.
Thanks for watching and taking time to comment. Regrettably we are a small island with less sun hours than our friends over the pond. I'm not aware of any uk manufacturers of these batteries, they are all made in China as is everything these days. At the end of the day they only have to use better bms systems with temperature options. I've built a couple of packs with upgraded bms and on others I use a smart battery sense that connects with my mppt to monitor temperature etc.
I have a new echo 12 volt 100ah and it won't hold a charge
Can you elaborate what the issue was and any outcome updates? Thanks
Hi, great videos you seem to really know your stuff.
Wondering if you’ve ever seen a battery do this
czcams.com/users/shortsb5BzoLq1poE?feature=share
According to Renogy this isn’t faulty?
Seems like a BMS fault to me, I’d love to know your thoughts.
The link doesn't appear to work 😕
