• Maintenance-Free & Lightweight – Only 22 lbs, with virtually zero maintenance required.

• Low Self-Discharge Rate – Less than 3% per month, ideal for long-term storage or seasonal use.

• 8-Year Warranty – Provides peace of mind and long-term reliability.

Technical Specifications

Performance You Can Rely On

This battery’s 100A continuous discharge rate means it can deliver 1.28 kW of continuous power, perfect for running inverters, trolling motors, or large appliances. The flat voltage curve of LiFePO₄ chemistry ensures steady performance throughout discharge, unlike lead-acid batteries that lose power quickly as they drain.

Its low internal resistance keeps heat buildup minimal, increasing efficiency and extending lifespan. Whether you’re powering your RV, boat, solar setup, or backup power system, this battery provides dependable energy whenever you need it.
