This 12V 172Ah powerhouse merges relentless deep-cycle endurance with genuine engine-cranking muscle, so you can run your trolling motor and electronics all day and still fire up your outboard without a second battery. Premium LiFePO4 cells and a cranking-rated smart BMS push out a massive 1,000A starting burst while delivering 200A continuous discharge for fish finders, pumps, and onboard gear.

Built tough in a sealed IP65 Group 31 case, it shrugs off spray and pounding waves, and Bluetooth monitoring puts real-time voltage, current, and state of charge right on your phone. Backed by an 11-year warranty and 4,000-plus cycles, it is the single-battery solution that keeps you on the water longer.
