Group 49 Lithium Iron Phosphate Deep Cycle Battery, 36V 72Ah, ABYC Certified

WEST MARINE Group 49 Lithium Iron Phosphate Deep Cycle Battery, 36V 72Ah, ABYC Certified

Extended range meets peak performance. The WEST MARINE Group 49 Lithium Iron Phosphate Deep Cycle Battery in 36V 72Ah is purpose-built for serious anglers and boaters who demand maximum runtime without sacrificing trolling motor power or system reliability. This is the deep cycle battery for extended fishing days, tournament conditions, and any situation where staying on the water longer means staying competitive. At 36 volts with 72 Ah of capacity, this battery delivers the voltage platform and amp-hour reserve that dedicated trolling motor users depend on, providing superior efficiency and extended range compared to lower-voltage alternatives.

Built on chemically stable, resilient LiFePO4 chemistry, the advanced battery management system protects against overcharge and over-discharge while maintaining an IP65 rating for harsh saltwater and freshwater marine environments. With exceptionally high energy density and power output, this Group 49 lithium battery delivers up to 10 times the lifespan of traditional lead-acid alternatives, translating to years of dependable service and substantial cost savings that compound over time. The lightweight design won't burden your vessel's weight distribution or compromise fuel efficiency the way heavier lead-acid batteries do, keeping your boat responsive and economical whether you're working in shallow water or covering open flats.

Deep discharge capability means you can safely access the full 72Ah capacity without worrying about cell damage or premature degradation, giving you genuine reserve power that carries you through full days on the water. Stable voltage output keeps your high-performance trolling motor running at peak efficiency, your navigation systems operating reliably, and your electronics delivering consistent performance throughout every charge cycle.

Fast-charging efficiency gets you back on the water quickly with minimal downtime between trips, while zero maintenance requirements and eco-friendly LiFePO4 chemistry eliminate the sulfation and corrosion that plague conventional marine batteries. This is a 36-volt deep-cycle power engineered for serious applications: maximum amp-hour capacity, peak trolling motor efficiency, and the reliability to deliver day after day.

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.
