Our take on the ExpertPower 12V Lithium LiFePO4 Deep Cycle Rechargeable Battery

The ExpertPower 12V 10Ah is a small LiFePO4 deep-cycle battery built for backup power, alarms, fish finders, solar lights and other low-draw 12V gear. It weighs 2.7 lbs and measures 6 x 2.6 x 3.7 inches, so it drops into many cases and boxes that a lead-acid block would not. ExpertPower rates it at 4,000 to 7,000 cycles and a 10-year shelf life, with cell-level UL1642 certification. At $34.99 at eBay as of November 5, 2026, it sits at the low end of its recent range, and only 2 stores price it new.

Questions and answers

Is $34.99 a good price for this battery?
It is the lowest new price among the 2 stores listing it as of November 5, 2026, and it sits at the low end of its recent range. At this capacity, that is a fair price for a LiFePO4 pack.
Can I use it to start an engine or run a trolling motor?
No. At 10Ah it is a deep-cycle pack for small loads like fish finders, alarms and lights. It cannot deliver the burst current an engine starter or trolling motor needs.
What charger does it need?
Use a charger with a LiFePO4 profile, typically 14.4 to 14.6V absorption. A standard lead-acid charger can overcharge it or stop short.
What size is it, and will it fit my battery box?
It measures 6 x 2.6 x 3.7 inches and weighs 2.7 lbs. Check your box and terminal spacing, since it is smaller than most 12V lead-acid blocks.
How long will it last?
ExpertPower rates it at 4,000 to 7,000 cycles and a 10-year shelf life. Real life depends on depth of discharge and charging habits.
What is in the box?
The battery itself. Terminals are F2 spade type, so buy connectors or adapters separately if your gear uses ring terminals.
