This 2 pack of ECO WORTHY 12 volt 280 amp hour LiFePO4 batteries stands out for strong value per watt hour and flexible use in RV, camper, trailer, solar, and backup setups. The batteries are being used successfully for truck campers, enclosed trailers, sump pump backup, and fridge, freezer, and network equipment emergencies. The pack can also be charged with an ECO WORTHY 12 volt 24 volt 20 amp smart battery charger maintainer, and the BMS amp rating should stay above the motor or load peak draw. Caveats include Bluetooth BMS connection failures on some units and warranty friction for matched multi battery banks.
The batteries can deliver strong value on a per-Wh basis for 12V setups.
The batteries can run a 12V fridge for about 10 to 14 days in real use.
The batteries can support emergency sump pump backup and keep fridge-freezer and network equipment running.
The batteries can be charged using an ECO-Worthy 12V/24V 20A smart charger maintainer.
Bluetooth BMS connectivity can stop responding, preventing app connections after months of use.
Warranty handling for series or parallel battery banks can require paying out of pocket for a matched replacement.
Charging and balancing performance can degrade over time, including not fully charging and becoming out of balance.

The measurements are published in the listing. you should have measured your needs prior to ordering.
This shouldn't be on the company since they are expensive to ship, and then it is no longer new, so it'd have to be relisted as such, discounted, and shipped for a third time.
Eat the loss. Sell it on marketplace or craig's list at a slight discount.
