The Epoch 36V 100Ah is a LiFePO4 marine battery rated at 3.84kWh, built to run 36V trolling motors without the weight of three lead-acid batteries. It is aimed at anglers and boat owners replacing a 36V lead-acid bank who want longer runtime and a lighter boat. Against lead-acid it wins on weight and usable capacity; against premium lithium brands it is a straightforward, single-voltage pack rather than a smart battery with app monitoring. Buyers rate it highly, and the main caveats are that it is a dedicated 36V unit, not a 12V battery you can wire in series, and it needs a compatible lithium charger.
