I have a power station but its internal battery is a 48 V, so when I run 12 V things you lose some efficiency stepping it down to 12 V. I also have a 12 V battery and I'll just often run those device devices directly from the battery and I get much more run time per ah of battery.
Community Reviews
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.

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.
With the XT60i, it will let you charge up to 15 amps, which would be 192 watts input (15amps x 12.8v). If you get 2, you can do a 24v setup and do up to 384 watts (depending on which ecoflow unit you have). You will need to buy a charger for the battery though made for LiFePo4 batteries.
I have a 100ah 12v battery with an XT60i connection hooked up to my river 3 plus and it charges at about 175 watts from the battery. I will be getting a 2nd battery soon to do 24v (River 3 Plus maxes out at 220v solar input).
Tons of you tube videos doing this.

The 150's are on a food truck and we can generally run it all day on the refer units plus solar without having to run a generator, which is really nice. Charge them quickly with a plug in ac to DC 60 amp charger overnight.
I've bought 4 of the 280's for our bus conversion and had to return 1 because the Bluetooth wouldn't work and it wasn't registering a full state of charge with an ac to DC charger controller which made me real nervous. No issues with the return and repurchase. We run a diesel all winter and these are on a manual timer to fire up the glow plugs from 4:00 to 6:30 am so the bus is easy to start in -20ish weather. Works like a charm, mostly recharge off the solar but have to plug in occasionally.

Will it charge when I plug in the trailer to ac power?
Do I need to add anything?
