The Bluetooth battery monitor lets you check state of charge, voltage, current, temperature, and battery status in the free Epoch Li-Ion app for iOS and Android, measured by a shunt built into the BMS.

This battery is built around a BCI Group 31 footprint and measures 13.0 in L × 6.8 in W × 9.44 in H (330.2 × 172.7 × 239.8 mm). It suits many Group 31 trays and straps, but it is not a drop-in replacement for every lead-acid or AGM installation, so verify tray size, cable clearance, terminal orientation, and hold-down fitment before installation.

Runtime is roughly usable amp-hours divided by the motor’s average current draw: a 10A average draw gives about 4 hours, and a steady 500W load about 3.1 hours. Thrust setting, motor efficiency, boat weight, wind, current, and temperature change real-world results. For extended runtime, up to four batteries can be wired in parallel (up to 200Ah).\n        \u003c\/p\u003e\n      \u003c\/details\u003e\n      \u003cdetails style=\"background:#FFFFFF; border:1px solid #E2E8F0; border-left:5px solid #ED1B4A; border-radius:10px; padding:18px;\"\u003e\n        \u003csummary style=\"cursor:pointer; color:#1A202C; font-weight:700; font-size:16px; line-height:1.45;\"\u003e\n          Do I need a special charger for this 36V lithium battery?\n        \u003c\/summary\u003e\n        \u003cp style=\"margin:14px 0 0 0; color:#2D3748;\"\u003e\n          Yes. Use a 36V charger with a LiFePO4 profile or a programmable lithium charger, such as the Epoch 36V 15A LiFePO4 battery charger; do not use lead-acid, AGM, or gel profiles. Recommended settings: 42.6V–43.2V bulk\/absorption, ending when charge current falls to C\/20 (2.5A) or after 15 minutes, whichever comes first; float disabled (preferred) or 40.0V–40.8V; re-bulk at 39.6V; equalization disabled; temperature compensation 0mV\/°C (off).

The free Epoch Li-Ion app for iOS and Android shows state of charge, voltage, current, temperature, and battery status, helping anglers track remaining power while on the water. Current is measured by a shunt built into the BMS (0.2A accuracy on discharge), so no external shunt is needed. The app asks for the Bluetooth security PIN printed on the battery’s lid the first time you connect; you can change the PIN in the app.\n        \u003c\/p\u003e\n      \u003c\/details\u003e\n      \u003cdetails style=\"background:#FFFFFF; border:1px solid #E2E8F0; border-left:5px solid #5EBB46; border-radius:10px; padding:18px;\"\u003e\n        \u003csummary style=\"cursor:pointer; color:#1A202C; font-weight:700; font-size:16px; line-height:1.45;\"\u003e\n          Does internal heating mean I can charge in freezing conditions?\n        \u003c\/summary\u003e\n        \u003cp style=\"margin:14px 0 0 0; color:#2D3748;\"\u003e\n          Yes, with a charger connected. The battery is rated to charge from -20°C to 55°C (-4°F to 131°F) with its internal heating. At 0°C (32°F) the BMS disables charging and the incoming charge current (a LiFePO4 charger supplying at least 0.5A) powers the heating pads instead; charging resumes automatically once the battery reaches 5°C (41°F). The heater never uses stored battery energy, so it does not warm the battery during discharge or storage, and the cells never take charge below 0°C.

Runtime is roughly usable amp-hours divided by the motor’s average current draw: a 10A average draw gives about 4 hours, and a steady 500W load about 3.1 hours.
