This 2 pack of ECO WORTHY 12 volt 280 amp hour LiFePO4 batteries stands out for strong value per watt hour and flexible use in RV, camper, trailer, solar, and backup setups. The batteries are being used successfully for truck campers, enclosed trailers, sump pump backup, and fridge, freezer, and network equipment emergencies. The pack can also be charged with an ECO WORTHY 12 volt 24 volt 20 amp smart battery charger maintainer, and the BMS amp rating should stay above the motor or load peak draw. Caveats include Bluetooth BMS connection failures on some units and warranty friction for matched multi battery banks.

$75/kWh...that's getting cheap.Can you string these together in Series to get 48v?
So I bought 4 of these maybe 10 months agoInitially they were fine and running wellThe last couple of months they started to show issues - not fully charging, quick drain, totally out of balance - even with a balancerI had bought them via Amazon at around $1600 so I contacted eco worthy via that routeI went back and forth for a couple of weeks doing every test eco worthy asked me to do - sent around 30 pictures of the eco worthy app as well as from my voltage meterI was getting blamed for everything - wrong charge controller, wrong settings, balancer not working etc etcGo to the point that I said I would simply go through Amazon as clearly I was not getting anywhereIn the end, I actually got my full money back - but it was a major struggle, even though they are all still under warrantyMaybe I was simply unlucky as I know these are a huge seller and really popular- Will Prowse also highly recommends them

waiting for one to go back down to 220.
Yeah I thought I'd see them back in the 220-240 range again. It's been a while. Cheapest was 250 last week.

I am currently dealing with EcoWorthy through AliExpress, and this has been, without question, the worst customer service experience I have had in over 50 years. What should have been a simple return has turned into an ongoing, frustrating ordeal. The batteries I purchased do not fit, yet after over a month, I am still being given the runaround with no resolution in sight. The level of inefficiency, lack of accountability, and overall disregard for the customer is frankly unacceptable. Based on this experience, I strongly caution anyone considering a purchase to think twice. I would not consider buying from this seller again under any circumstances.
Doesn't fit???

The measurements are published in the listing. you should have measured your needs prior to ordering.

This shouldn't be on the company since they are expensive to ship, and then it is no longer new, so it'd have to be relisted as such, discounted, and shipped for a third time.

Eat the loss. Sell it on marketplace or craig's list at a slight discount.

Is there a wiring kit or guide on how to hookup 3 of these in parallel so I can add them to provide 10kw of backup power? Also whats a recommended charger thats over 20amp for these. I have one battery already and going to buy two more.

What do you all use these for as standalone units? That might be a dumb question, so sorry. I'm used to batteries as backups for something, so wondering what all that is. I'm trying to assemble a whole home backup, but feels like these perhaps are not the way to go to create a 48V system + inverter?

I can't access Ali right now but look for the BMS rating in amps. As long as the max/peak draw of your motor is below that it'll be fine.

I've got a few of these for sump pump backup power and fridge/freezer/network equipment emergency and they've been great.

really good price per whI'm still holding out for anything on the 48v's
Try ebay. Last week there was a bundle with the 48v 100ah, 48v 60a charger, and a touchscreen monitor for the battery for $799 sold by ecoworthy.

How difficult is it to change an RV from lead acid to these?
