Community Reviews
This 12V 50Ah LiFePO4 battery stands out as a compact, lightweight option for small trolling motors, backup power, and other low to moderate draw setups. The flat discharge curve and higher usable capacity versus lead acid make it easier to avoid frequent recharging, and the battery has been used in series or parallel for larger systems. Real world reports include a full day of fishing, long offshore trips with minimal drain, and a working UPS backup setup. The main caveats are its limited capacity for golf carts or cars, plus coupon and limit issues at checkout. A practical pick when size and lithium efficiency matter more than raw capacity.
Common Questions (5)
You need a LiFePO4 charger matched to the battery chemistry, not a lead-acid/AGM charger. The correct voltage depends on how the batteries are wired internally, so a 12V or 36V charger choice should follow the actual series/parallel configuration.
Two of these batteries cost about $132, which is still below many small 24V lithium batteries that often run closer to $200. That makes the 12V pair a cheaper way to reach similar capacity, though a single 24V battery can be simpler to charge and balance.
Yes, the manufacturer website says it can be used in series or in parallel. That makes it suitable for building a 24V bank from two 12V batteries, though wiring and charging still need to match the setup.
It can work for a trolling motor, and one user reports using the exact ECO-WORTHY 12V 50Ah battery for 3 years without issues and getting a full day of fishing. Another warns the 50Ah size is limited capacity, so runtime depends heavily on motor draw and use case.
Yes, it can power a UPS backup setup. One user wired it to a CyberPower CP1000PFCLCD with a breaker and proper terminals, then tested it by unplugging the wall power and the connected PC, monitor, modem, and router stayed on.

This would be perfect raffle prizes for our ham club's Christmas party.
Bummer, limit 1 and I can't get the coupon to work.

Going to convert the golf cart here pretty soon as I'm tired of cleaning all the acid residue accumulating on the tops of the Trojan batteries every month. What a mess. (and these batts are only a year old).

Nobody makes a 24v 25ah battery(comparable capacity) and the smallest 24v 50ah battery sells closer to $200.
2 of these is $132 and that's closer to the popular 12v 100ah prices.
You can find smaller 24v but they are usually expensive.
If anyone can find a 24v 50ah(same as a 12v 100ah) for under $150, LMK.
