Exceptional dual-purpose power for starting and deep-cycling all on one battery. Dual-Purpose Performance: Deliver a massive 1200 Cold Cranking Amps (CCA) to effortlessly start your marine engines while reserving 160Ah of deep-cycle capacity for house electronics. Massive Weight Reduction: Weighing only 38 lbs, this lithium battery shaves substantial weight off your vessel compared to traditional lead-acid equivalents, instantly improving speed and fuel efficiency. Intelligent Safety: Built with an Advanced Battery Management System (BMS) equipped with active cell balancing, low-voltage disconnect, and a reliable low-temperature charging cutoff. Proven Longevity: Engineered to provide 5,000+ cycles at 80% Depth of Discharge, maximizing your return on investment over years of harsh marine use. What This Upgrade Fixes Eliminate the anxiety of a dead starter battery after running trolling motors and electronics all day long. This upgrade ends the routine maintenance, heavy lifting, and frequent replacements associated with traditional lead-acid marine batteries. It also solves the problem of underperforming electronics caused by voltage sag—our LiFePO4 chemistry holds a steady voltage until completely depleted. What's Included [FILL: WHAT'S INCLUDED] Compatibility This is a universal flat-fit design manufactured in the standard Group 31 form factor, meaning it works as a direct drop-in replacement for existing Group 31 marine or RV battery setups. It operates seamlessly with standard 12V alternators and marine charging systems supporting a 14.2V - 14.6V charging profile. Ideal for marine house power, engine cranking, RV house banks, trolling motors, and solar storage applications. Installation Estimated Time: 15–30 minutes Difficulty: Beginner Tools Needed: Basic socket set or wrench to disconnect the old battery and torque your existing ring terminals onto the new battery posts.

Yes. Unlike standard deep-cycle lithium batteries, this unit pushes 1200 CCA designed specifically for engine cranking, alongside providing 160Ah of true deep-cycle energy storage for motors and electronics. Will this fit in my existing battery tray? Yes, this is built precisely to a Group 31 blueprint. As long as your current setup accommodates a standard Group 31 battery, it is a simple drop-in swap. Will the battery be damaged if I charge it in freezing weather? No. The integrated BMS includes a low-temperature charging cutoff. If the internal temperature drops below 0°C (32°F), it automatically prevents a charge to protect the lithium cells from permanent damage.
