• Dual-Purpose Power Revolution: Enjoy the advanced 2-in-1 Lithium power solution that combines engine starting and deep-cycle power – replacing 2 lead-acid batteries with a single unit 75% lighter. No more wiring headaches thanks to simplified setup. Even in the pursuit of trophy bass fishing in shallow waters, where traditional heavy lead-acid batteries can’t reach.
• Endurance Powerhouse: Integrated LiFePO4 technology enables 5,000+ engine starts & 4,000+ cycles at 100% DOD(10-year deep cycle lifespan), outperforming lead-acid batteries’ 200-300-start lifespan or 2-3 year lifespan in deep cycle use with zero maintenance. Ideal for even chasing fish in shallow bays or powering navigation systems during offshore voyages; Spend more time adventuring.
• Unchained Marine Power: Exclusive Reserve Lock technology auto-preserves 25% charge for emergency starts. The dual-purpose battery packs 900 CCA punch, compatible with all outboard motors, backed by 4P (starting) or 4P4S (deep cycle) expandable architecture. With quard-mode charging (outboard/shore/solar/alternator)  and 1kWh capacity for 8-10hr nonstop gear – Fish from sunup to sundown, free from power anxiety.
• Smart Zero-Retrofit Power: With industry-first Bluetooth OTA upgrades, this Group 27 marine battery offers continuous performance optimization and real-time status monitoring via a smart app. Its drop-in design fits seamlessly into Group 27 / 31 battery compartments (90% boats)—no retrofitting or dual-battery hassles.
• All-Weather Marine Power: Constructed with IP67 waterproof & salt-spray-proof, this dual-purpose lithium marine battery activates auto-heating at 41°F to ensure charging readiness even in −4°F Arctic conditions, eliminating lead-acid batteries’ fatal flaws of freezing-induced failure and acid leakage risks. No more winter charging delays or saltwater corrosion nightmares — just all-weather power for starting, trolling motors, navigation systems, and emergency calls.
