This 12V 280Ah LiFePO4 battery is being used as affordable house, RV, boat, camper, and off-grid storage, with Bluetooth monitoring and enough capacity for serious loads. It is praised for running 12V devices directly, pairing well with solar, and scaling into 24V or 48V banks for larger systems. Real-world reports include trolling motors, backup power, and even air conditioning, though runtime drops fast on heavy AC loads. It is not a starter battery, and charging or wiring often needs the right lithium charger, fuses, and connectors.

Common Questions (7)

  • Yes. It is being used in RVs, campers, boats, trailers, and for trolling motors, and it is well suited to 12V loads because you can run devices directly without an inverter. It is also commonly paired with solar for off-grid storage.

  • You need a solar charge controller to charge it from panels, and lithium-compatible charging settings are important. For faster charging into EcoFlow units, an XT60i cable can allow up to about 15A input, while a standard XT60 is often limited to about 8A.

  • Yes. Four of these can be wired in series for a 48V bank, and users also report 25.6V series-parallel and 36V golf-cart setups. A lithium charger and proper fusing or disconnects are recommended for those builds.

  • No. It is a power-storage battery, not a starter battery, and the 200A BMS is not meant to supply the several hundred amps vehicles need for cranking. It can fit some vehicle-sized spaces, but it will not replace a car battery for starting.

  • It may, because 12.8V × 280Ah equals 3.584kWh, which is above the 3kWh threshold mentioned for the credit. The battery would need to be installed and used for home power, and the credit discussion was tied to a Dec. 31 deadline.

  • Runtime depends heavily on the AC load and whether it is maintaining temperature or cooling hard. A standard 13,500 BTU unit running constantly was estimated at under 3 hours, while a lighter 5A/120V load works out to about 5 hours after inverter losses.

  • Yes, it has Bluetooth, and the listed low-temperature protection stops charging below -7°C and resumes at 0°C. One unit was also reported to work with the DBJBD BMS and the Overkill Solar app.

Be cautious of this seller, as it might be a fake. While the battery is great, this seller might be a scam.
I ordered two on Friday, just received the tracking yesterday and it started moving today. Ships via Fedex from NJ. Weight shows 65lbs which is in line with the other batteries I ordered from them.
I've ordered maybe a dozen things from Eco-Worthy, they all ship from random warehouses across the country.

Can I place 4 separate orders and use the coupon each time?

@gabe23111 or anyone else
Yes, I posted earlier that I did this but my post was deleted because I mentioned a certain cashback.

I got the ebay deal, and I saw this afterwards. It seems the ebay deal has already expired. The additional 4 that I bought just arrived yesterday, and now system is around 40Kwh. These eco-worthy has been great so far for 48V system. I also set up a series battery balancer, but I had to replace it recently. This is more cost effective than the server rack battery.

can i replace this battery with my current 12v on my chevy Silverado?
No. Your vehicle, especially a truck would take 600amps or more to crank. The 200amp BMS would cut the power off. This would be a good choice for an audio system, or for power storage for a RV or something like that.

Do you keep these in your garage or a separate shack just in case? I'm planning my solar system.

Good deal but these are not $1059 normally. Was looking at them a couple months ago on Amazon and they were around $440 each.

I keep mine in a shed, just because it is quite a messy. I don't really care about how it looks as long as it works, but my wife begs to differ. To me, a solar system is a long term investment, I'd get good solar panels (N-type TOPCON is great choice, and don't buy eco-worthy panels). I'd recommend Victron for electronics and get separate MPPT solar charger and inverter. With Victron, you can start small, and expand your system as you go. I don't think that you need expensive batteries, because battery technology changes pretty rapidly these days.

You can use any pwm or mppt solar charger straight to the battery. It all depends on your solar panels and your usage/needs. Your solar panels total Voc should be 20% below your MPPT voltage, and your solar panels total voc should be greater than your total battery voltage (for 12V, this should not be a problem).

If you are converting to A/C (alternating current), I'd recommend at least getting 2 batteries and wire them in series (24V DC) to reduce energy loss (48V is a good compromise).

I was planning to buy two and connect them in series and charge them with two 12v solar connected in series as well. I also want to connect to inverter when they charge is finished. What is a recommended charger that I can use to accomplish this?

No, it is not a simple drop-in conversion from FLA batteries. You may need a different charger/ converter, solar charge controller, and most likely some way to protect your campers alternator from burning out.
Thank you for the information.

How did you get 20% CB? I see 10% for new members (and 6% for me).

What are these used for in always seeing them posted
They have a longer duty cycle. (charge/discharge)
