LiFePO4 voltage stays nearly flat across most of the discharge, so your trolling motor sees steady voltage through most of the battery’s usable capacity. For planning, Epoch uses 80% of nominal energy, about 3,072Wh (80Ah): roughly 8 hours at a 10A load or 6.1 hours at 500W.\u003c\/p\u003e\n\u003cp style=\"margin: 0; color: #2d3748;\"\u003eUse it with compatible 36V trolling motors from brands such as Minn Kota, Garmin, and Lowrance when voltage, current draw, fuse protection, charger profile, and manufacturer battery requirements match.
