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.

No. This is way bigger than a car battery. It's for power storage. I got two of them in my trailer. Works well - you can run the air conditioner for 8 hours off them.
You must have a small AC unit..most AC units use closer to 1350 watts. That battery will last less than 3 hours with a standard 13500 btu unit running constantly.

It's about the same size as a car battery, but it definitely can't be used as such.
Actually it's not, this one is roughly twice as large as a standard automotive 12v.

It really depends. If your AC is running full power full blast then yes it will drain this pretty fast. However most of the time AC will be running at lower power, just maintaining the temperature in the home.

Think of a fridge. It takes a lot of power momentarily starting up, a decent amount bringing temperature down to levels and then very little maintaining that temperature.

But yes if you are trying to cool your room from 100f down to 70f it won't last long. However maintaining 70f takes much less power.

I bought these at $376 each in February 2025, $434 In May 2024 on ecoworthy store on eBay, and thought I had gotten amazing deals. They arived from China intact. This store on AliExpress has 100% positive reviews, 4.9. I think this is legit. If I didn't have 4 batteries sitting in my closet, I would bite...

Ok, I put my money where my mouth is and bought another. Lithium is so much better than lead. They can be discharged more deeply, giving more usable charge. Lighter. LiFePO4 has better temp range. Others have reported 300 AH for this battery as well.

Huh? Nope. Extreme temps are challenging for LFP batteries. At least compared to lead acid type batteries.

can i use this to charge my ecoflow power station?<br />
<br />
Im thinking of connecting it using alligator clips from 12v batt to xt60 to the back of the power station. not sure if this will work and advisable.
Yes, definitely. I now have 4 of these in a 25.6V series parallel bank configuration providing power to an Eco-Flow Delta 3 Plus via the XT60i inputs.

I charge the battery bank from solar through a Redodo charge controller.

Lol. These were NEVER $1,055. These "sale" prices are ridiculous. Like it's still a good deal. I bought two of these at ~$300 each last year and love them, but please they need to stop saying they're marking it down 75%!
