The Epoch 12V 300Ah Group 8D LiFePO4 battery is designed for both engine starting and deep-cycle power applications. It delivers up to 1,000A of peak discharge for 5 seconds and 800A for 10 seconds, providing the power needed to start compatible marine engines. Epoch specifically notes compatibility with Mercury 250 hp motors when the electrical system is properly matched.

Unlike standard deep-cycle lithium batteries that may shut down under engine-starting loads, the Epoch 12V 172Ah Dual Purpose battery uses a cranking-capable BMS and is rated for 1,000A peak discharge for 5 seconds, roughly equivalent to 1,000 CCA.
