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.

How did you get $15 discount while paying with PayPal?
I just see the $56 promo code discount during checkout with PayPal
The $15 discount would have been automatically added to your PayPal payment. It is limited to the Promotion quota of 3,467 rewards, so all must have been redeemed.

If you really want, drag a long 0 or 1 AWG into a spot that has room for the battery.
It does not have the CCA to start a car.

Would this be good to run a trolling motor on a canoe?

A very large canoe going very long distances! For a Canoe you might consider a 100ah. Whatever floats your boat.

Kinda, they're normally 500, 300 is considered a deal, but with tariffs it's been wonky.

Anything under 300 for this capacity should be considered a deal and at 230 it's the cheapest I've seen. I think the only way to get it cheaper would be second hand market or to steal it from someone's boat.

Can this be used as maintenance-free battery for WatchDog backup sump pump.
without knowing the model and assuming its lead acid battery design (NO)

Wonder if you could use 4x in golf cart. 14kw @51.2v with extension cable to portable power station or 48v inverter.....
i would say no....
Maximum continuous discharge 200A
so 200Amp @ 48V = 9.6KW. so you will be running the BMS in the red zone will only take one hot day and you will pop those transistors in the battery.
