Epoch 24V 50Ah | Heated & Bluetooth | LiFePO4 Battery

This is Epoch's 24V 50Ah LiFePO4 battery, a smaller-footprint deep cycle option built for 24-volt systems like trolling motors, smaller marine setups, and off-grid applications that don't need the higher capacity of Epoch's 100Ah 24V battery. It stores its capacity across an 8S cell configuration, delivering 100A of continuous discharge with the flat, consistent voltage output characteristic of LiFePO4 chemistry.

Internal self-heating supports charging down to -20°C (-4°F), letting the battery keep working through cold snaps that would stop many lithium batteries from accepting a charge at all. The sealed IP67 housing protects against dust and water intrusion, while Bluetooth connectivity lets you monitor state of charge, voltage, and temperature from Epoch's mobile app rather than relying on a simple charge indicator light.

At 34 lbs, this battery is a substantial weight reduction compared to the lead-acid batteries it typically replaces in a 24V bank. It supports wiring up to 2 units in series alongside up to 4 in parallel, giving some flexibility to scale either voltage or total capacity depending on the system. Built-in BMS protection covers overcharge, over-discharge, over-current, short-circuit, and temperature extremes, backed by a 3,500+ cycle life rating and an 11-year manufacturer warranty.
