Our take on the DJLBERMPW 12V 30Ah LiFePO4 Deep Cycle Lithium Marine Battery

A small 12V 30Ah lithium iron phosphate battery rated at 384Wh, built from Grade-A prismatic cells with a 30A smart BMS. It is light at about 7 lbs and rated for 4000 to 15000 cycles, so it suits trolling motors, fish finders, kayak setups, campers and small solar builds. It can be wired in series or parallel up to 4S/4P/4P4S for 48V systems. Against lead-acid equivalents it is far lighter and lasts many more cycles, but its 30A BMS limits it to modest loads, so it is not a starter battery or a fit for high-draw inverters.

Questions and answers

Can I use it to start an engine?
No. The 30A BMS limits current, so it is a deep-cycle battery for electronics and trolling motors, not a cranking battery.
Can I wire several together?
Yes. It supports up to 4 in series, 4 in parallel, or 4P4S, which gives a 48V system from four in series.
How long will it run a trolling motor?
It holds 384Wh, so a motor drawing around 20A runs roughly an hour and a half. Higher draw shortens that, and the 30A BMS caps output.
Is it lighter than a lead-acid battery?
Yes. At about 7 lbs it is far lighter than a comparable 12V lead-acid deep-cycle battery, which matters on kayaks and small boats.
What charger should I use?
A LiFePO4-compatible 12V charger. Check that its charge voltage matches the battery's spec before charging.
Where is the DJLBERMPW 12V 30Ah LiFePO4 Deep Cycle Lithium Marine Battery cheapest?
