Eco-Worthy 12V 100AH LiFePO4 w/ BMS $164.80 + Free Shipping

[BarracudaBob]

I don't like how the pouches don't have a compression fitting like for example the Redodo minis. But maybe that's the difference between old and "new"? Probably the same with the 24V 100Ah and I haven't had any issues with two in series.

I wrapped the crap out of mine with fiber tape. They ran for 2 years before I opened them and looked perfect. Almost wish I didn't open them because the HC02 balancer was working so nicely. I loved those qual volt meters.

The 12V 150Ah Eco-Worthy metal battery arrived today. Has Bluetooth and low temp protection.
Interesting enough, the BMS claims that it's a 165Ah battery.
Was able to charge it to 99% using an EcoFlow Alternator Charger. It only reverse charges at 13.8V so it could not top it off. Had to connect a Battery Tender 4.5A set to LiFePO4 mode to get it to 100%.
Cells are imbalanced. The forth cell is like 0.1V higher.

I attempted opening the case but the screws were so tight that I stripped one trying to unscrew it. Not proud of myself there.
Peeked inside by holding up one side of the cover and it looked reasonably decent to my untrained eye.

After sitting for a day cell voltage has magically equalized. Not sure if that's normal or not?

Guess bluetooth revision changed it?

Lice where you can get to the cells, balanced out nicely. Bluetooth app to monitor everything, What's not to love

Looks like the same metal case they use for the 50Ah 48V version. There’s plenty of extra space in that one.

Did these end up being 150 or 165AH? Getting extra 15AH is nice, but true.

I don't have a shunt to check but the BMS still reports 165Ah after a full discharge and full charge.

Crack that nut and lets get some pictures

I received 1 of 4, hopefully the other 3 yet today. I charged it at ~15A rate. It came in with 40% SOC, the cell Voltages were all pretty close. It took about 7h to get to 100% (165Ah) which seemed about right. It sent out an "Over Voltage" notification at the very end of the charge. Pic attached. I'm letting it rest hoping it balances itself out in time and it seems to be balancing. I'm curious if this is normal? These are my first with Bluetooth visibility. I could see the first time charge bulk be out of balance in the end, I just want to make sure. All in all, a great deal so far.

It uses a JBD BMS. Find an app that shows more info.
My cells were really out of balance on the first charge as it approached 100%. After rest they are now perfectly balanced.
Bought a second one for $213 as I want to put them in series for 24V. Will attempt a price match if they go lower, it has a 30 day return policy with free return shipping so I think they'll be keen to price match.

Thanks. The 1st battery is now balanced after resting and the overvoltage notification went away as it balanced. 2 more have finished charging and no overvoltage notifications. As you say, the imbalance appears as they approached 100%, with it's exponential voltage curve at the end. I put the first one back on the charger and it topped off without an overvoltage notification. So I guess that notification wasn't a real problem.

Good ole Will. Just published. LiFePO4 Charging Guidelines: What is 100%? What is 0%?! How to Balance??

WOW.
That is an insane deal
$90/Kwh


I don't have any use for a straight up 12 volt battery and I legit think I'm going to buy one or three.

WOW! That's a great price! I'm all 24v here though. I'll pass it along to my ham friends as I'm sure they'd like to get in on it.

Just bought an Ecoflow alternator charger and looking to get this same battery too. Question for you: Are you planning to get the 2nd to run it at 24v with the alternator charger? Any benefit in doing that? I thought about doing that too, but also considering wiring them in parallel for the added capacity with the alternator charger

I plan to put it in series. Still doing initial cycles on the second one to calibrate the BMS before I put them in series. I'll let you guys know how it works with the alternator charger at 24V. It works fine at 12V, though it doesn't fully top off the battery as the alternator charge is only 13.8V when running in 12V mode. It gets it to 99%, but doesn't top balance it.

Let me know what you find. I'm considering the same, but was thinking of putting the two in parallel instead of series, especially if there's no added benefit of 24v with the alternator charger.

 

[ericfx1984]

A buddy of mine picked these up about 8 or 9 months ago... I was able to test them and they were slightly down on capacity when compared to their rating

When we did have a problem with their products, they were really hard to deal with and always seem to be speaking down to you... They would blame every other company under the sun and tell you how crappy every other company was... They even had crap to talk on battleborn... The most interesting part was all they had was glowing reviews to say about their own product

But for me I'm impressed when you can give me a quality product at a good price... But, like any product, it may fail or not even work properly to begin with... That happens... But what is really important is this, how do you handle the customer's issue when they have one... Now it's great that they were willing to replace the product... But it would have been better if they had treated my friend with respect...

No I've installed quite a few ecoworthy Solar setups in RVs around here... In fact I have a guy who's running his garage off of one

But after the issues they gave my friend... Nope ... No... Not a chance, never... Ain't going to happen... Not gonna to do it...

Also, what gauge wires will you use to connect them in series?

I bought a 1ft 1/0 gauge from WindyNation. Likely overkill though. Make sure you get 5/16" lugs (M8).

1/0 Gauge (AWG) Black and Red Pure Copper Battery Cable Wire with Lug

WindyNation is one of the nation's largest manufacturers of assembled inverter cables in the USA. Our cables are precisely cut and stripped on an automated robotic cable processing machine. Pure copper tin-coated cable lugs are then attached using a 6-ton pneumatic crimper with custom dies...
