Description
This EPOCH 12-volt, 100 Ah lithium iron phosphate (LiFePO4) battery is built for trolling-motor runtime and house loads such as electronics, lighting and pumps. At roughly 21 lb, it takes meaningful weight out of the boat compared with a lead-acid battery of similar usable capacity. The case follows a BCI 24 footprint; confirm your tray size and terminal orientation before you buy. Pair it with a charger that offers a LiFePO4/lithium charge profile.
