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.

  • The battery can be a strong value for energy storage, with multiple reports describing unusually low pricing compared with typical LiFePO4 battery pricing.

  • The battery can integrate into solar and EcoFlow systems, including setups that charge from solar and feed EcoFlow Delta units via XT60i inputs.

  • The battery can run 12V devices directly without an inverter, which can improve efficiency versus stepping down from a higher-voltage power station.

  • The battery supports real off-grid and RV use cases, including running an air conditioner for about eight hours in a trailer setup.

  • The battery can work well for backup power with an inverter, including a reported longest outage of about fourteen hours while still leaving remaining battery juice.

  • Coupon and checkout reliability can be inconsistent, including reports that promo codes fail to apply or stop working during checkout.

  • The battery is not intended for vehicle cranking, and it lacks the CCA needed to start a car.

  • The battery can drain quickly with high-power AC loads, and a 13500 BTU unit running constantly was estimated to last under three hours.

  • The battery may require careful charging compatibility, since some setups report Bluetooth not working and the battery not registering full state of charge with an AC-to-DC controller.

off grid solar, house batteries for rv, camper, boat. If you've got 12 V devices you can run that directly from the battery without any inverter which is nice.
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.

can i use this to charge my ecoflow power station?

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.

Probably. I don't know about that power station, but I do use a 12 V lithium to charge a bluetti power station at times. I do exactly like you've described. Alligator type clips to the DC/PV input.

It's not fast, typically 8-10amps or 100-120 watts input. I get 8.3 amps out of the external battery, 8 amps into the power station. Either a fuse block or an in-line fuse would be prudent for extended charging.

This is a 3.5kwh battery so if "installed" could qualify for tax credit too. Not a tax professional though.

can i replace this battery with my current 12v on my chevy Silverado?
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.

If you really want, drag a long 0 or 1 AWG into a spot that has room for the battery.

That's a crazy price for energy storage. I don't think the storage credit still exists, if it did this would be the lowest I had ever seen.

No. These are NOT starter batteries. That isn't how it works.
