Description
This EPOCH 36-volt, 50 Ah lithium iron phosphate (LiFePO4) battery is built for trolling-motor runtime. At roughly 35 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. Bluetooth monitoring lets you check state of charge from a phone app; internal heating protects the cells while charging in freezing weather; IP65 sealing (dust-tight and protected against water jets) helps it shrug off spray. Pair it with a charger that offers a LiFePO4/lithium charge profile.
