Built to withstand salt spray, constant vibration, and deep discharge cycles that define life at sea.
IP67-rated sealed aluminum housing with marine-grade coating resists corrosion in high-salinity environments for years of reliable service.
Monitor real-time voltage, current, temperature, and state-of-charge from your smartphone via the Ohm Battery app.
LiFePO₄ chemistry delivers over 5,000 charge/discharge cycles at 80% depth of discharge — 10x longer than lead-acid.
Up to 1C continuous discharge rate supports high-power trolling motors, inverters, and propulsion systems without voltage sag.
Compatible with standard marine chargers and shore-power systems. Built-in charging profiles for fast, safe recharging.
Standard BCI group sizes and terminal layouts mean direct replacement for existing lead-acid battery banks — no rewiring needed.
