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.
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.

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.
Maybe wait and see if the price will drop further in Black Friday!

Edit: Working now.
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.

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.
