Description
This EPOCH 12-volt, 314 Ah lithium iron phosphate (LiFePO4) battery is built for house loads such as electronics, lighting and pumps. At roughly 57 lb, it takes meaningful weight out of the boat compared with a lead-acid battery of similar usable capacity. The case follows a BCI 31 footprint; confirm your tray size and terminal orientation before you buy. Pair it with a charger that offers a LiFePO4/lithium charge profile.
