Description
This EPOCH 12-volt, 300 Ah lithium iron phosphate (LiFePO4) battery is built for engine starting and combined starting and deep-cycle service. At roughly 81 lb, it takes meaningful weight out of the boat compared with a lead-acid battery of similar usable capacity. The case follows a BCI 8D footprint footprint; confirm your tray size and terminal orientation before you buy. Bluetooth monitoring lets you check state of charge from a phone app; internal heating protects the cells while charging in freezing weather; IP67 sealing (dust-tight and rated for temporary immersion) helps it shrug off spray. Pair it with a charger that offers a LiFePO4/lithium charge profile.
