Group 31 Lithium Iron Phosphate Deep Cycle Battery, 12V 150Ah, ABYC Certified

WEST MARINE Group 31 Lithium Iron Phosphate Deep Cycle Battery, 12V 150Ah, ABYC Certified

Extend your time on the water with serious power that goes the distance. The WEST MARINE Group 31 Lithium Iron Phosphate Deep Cycle Battery is engineered for anglers, boaters, and water sports enthusiasts who demand extended runtime without compromise. With 12V 150Ah of reliable LiFePO4 chemistry, this deep-cycle battery delivers exceptional reserve power for trolling motors, marine electronics, and high-power audio systems that draw continuous current hour after hour.

Built on chemically stable, resilient LiFePO4 technology, the advanced battery management system protects against overcharge and over-discharge while maintaining an IP65 rating for unforgiving marine environments. You get up to 10 times the lifespan of traditional lead-acid batteries, translating to years of dependable service and substantial cost savings that serious boaters appreciate. The high-energy-density design means you're carrying more power without the weight burden that compromises vessel performance and fuel efficiency.

Unlike conventional deep-cycle batteries that lose voltage as they discharge, this Group 31 lithium battery maintains stable output throughout the entire discharge cycle, keeping your trolling motor, fish finder, and accessories running at peak performance all day long. Deep-discharge capability lets you safely pull every amp-hour from the battery without damaging cells, giving you the full capacity you paid for.

Fast-charging efficiency minimizes downtime between trips, while the eco-friendly LiFePO4 chemistry requires zero maintenance and eliminates the corrosive sulfation that degrades conventional marine batteries. This is deep cycle performance redefined: maximum reserve power, lightweight efficiency, and the reliability to back it all up.

This battery is ABYC certified, giving boat owners and marine professionals confidence that it meets established safety standards for use in recreational boats and marine electrical systems.

What is ABYC?

The American Boat & Yacht Council (ABYC) is a non-profit, member organization that develops voluntary global safety standards for the design, construction, maintenance, and repair of recreational boats. ABYC also provides standards-based technical education and training to help marine professionals build skills, stay current, and advance safety across the boating industry.
