Premium LiFePO4 Power for Extended Trolling, Marine House Banks, and Electric Propulsion.
Don’t let battery anxiety cut your time on the water short. Upgrade your vessel with the SpiderWay 150Ah Lithium Iron Phosphate (LiFePO4) Marine Battery. Engineered to handle harsh marine environments, this high-capacity powerhouse delivers a massive 7.68kWh of reliable energy for heavy-duty trolling motors, multi-day house loads, and electric boat propulsion—all at a fraction of the weight of traditional lead-acid or AGM banks.
Key Features
-
Massive 7.68kWh Capacity: Packed with high-density energy to keep your electronics suites, onboard appliances, or electric propulsion running all weekend without needing a dock hookup.
-
Constant Voltage & Power: Unlike lead-acid batteries that suffer from severe voltage drop as they deplete, SpiderWay lithium cells deliver 100% of their rated power right up until the battery is empty. Your trolling motor won't lose thrust halfway through the day.
-
Extreme 6,000-Cycle Lifespan: Built using premium LiFePO4 chemistry to outlast traditional AGM or flooded marine batteries by up to 15x, offering unparalleled long-term ROI.
-
Intelligent Marine BMS with CAN Port: Features an advanced Battery Management System with a built-in CAN communication port, allowing smart data integration while actively protecting against overcharging, overcurrent, and thermal spikes.
-
All-Weather Performance: Engineered to perform reliably across broad temperature ranges, allowing discharge down to -20°C for early winter or late autumn water outings.
