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.

I'm still holding out for anything on the 48v's

Can you string these together in Series to get 48v?

I bought a pair of Eco-Worthy batteries less than a year ago to run in series. One recently suffered a confirmed manufacturing defect. Eco-Worthy acknowledged the defect and confirmed it was well within the warranty window, but refused to send a free, matching replacement.
As we all know, putting a mismatched battery into a series bank compromises the whole system. Eco-Worthy explicitly admitted this in writing, stating that a matched production batch is a necessity for consistent performance.
Instead of honoring the warranty by providing an exact match or refurbished unit at no cost, they weaponized this technical necessity into a sales pitch. They offered a "goodwill BOGO deal" on their latest, more expensive model: they would give me a matched pair, but only if I paid out of pocket for one of them.
To get a "free" warranty replacement for a defective product under a year old, I was forced to buy a second battery I didn't need, at a higher price than my original purchase. They essentially held my broken system hostage until I agreed to buy more product.
I bought it under protest just to get my rig back online, but consider this a heads-up. If you run a multi-battery bank, Eco-Worthy's warranty policy is designed to extract more cash from you when their product fails.
