Our take on the 2 Pack LiFePO4 Deep Cycle Battery 12V 7Ah

This is a two-pack of 12V 7Ah lithium iron phosphate (LiFePO4) batteries with a built-in battery management system. Each one is a sealed, maintenance-free block about the size of a small lead-acid brick, rated for 4000+ deep cycles, which is far longer than the few hundred cycles a typical sealed lead-acid battery manages. The BMS protects against overcharge, over-discharge and short circuit, and the cells tolerate discharge down to -4°F and charge from 32°F. They suit small 12V loads like fish finders, camp lights, gate openers, kids' ride-on cars and backup power, not engine cranking or large inverters.

Questions and answers

Can these start a car or mower?
No. At 7Ah they are for small electronics and accessories. Use them for lights, fish finders, gate openers or backup, not cranking an engine.
Do I need a special charger?
Use a charger with a LiFePO4 setting or one rated for lithium. A lead-acid charger may stop short of full charge or overcharge them.
Can I wire the two together?
Yes, in series for 24V or in parallel for 14Ah, provided both are at the same charge level. Keep the pair matched.
Can I charge them in freezing weather?
No. Charging is rated from 32°F to 113°F. Discharging works down to -4°F, so warm them before charging in winter.
What comes in the box?
Two 12V 7Ah LiFePO4 batteries with built-in BMS and a user manual.
