Unlock next-level power with the NOCO Lithium NLX31 — a premium dual-purpose lithium battery that starts your engine and runs your gear. Designed as a Group 31 lithium iron phosphate (LiFePO4) battery for RVs, boats, campers, trailers, golf carts, overlanding rigs, generators, vans, car audio systems, battery backup systems, and off-grid solar installations, it delivers both starting performance and deep-cycle capacity in one powerful unit. With 120 amp-hours (1536Wh) of usable energy and a massive 1600-amp cranking current, it replaces traditional AGM and lead-acid batteries with a solution that's lighter, faster-charging, and longer lasting. Start your engine in seconds — then run high-demand appliances, heavy-duty inverters, and electric propulsion systems with confidence. Built with lithium iron phosphate (LiFePO4) chemistry, the NLX31 offers 2,000 cycles at 100% depth of discharge, 4,000 cycles at 80% DOD, and 6,000 cycles at 50% DOD — delivering decades of reliable power with zero maintenance and no sulfation. Recharging is lightning fast: with a 50A charger, full recharge takes just 2.4 hours; 4.8 hours with a 25A charger; and 12 hours with a 10A charger. Its quad-post terminals provide ultimate flexibility for installs, supporting series and parallel connections with SAE, threaded, and button head compatibility. And it's built tough. The advanced Battery Management System (BMS) continuously monitors temperature, voltage, and current, delivering passive cell balancing and complete protection — no reset required. Plus, its IP65-rated enclosure defends against water, dirt, and vibration, making it ideal for rugged and demanding environments. Whether you're powering an off-grid cabin, a large trolling motor system, or a full-size RV electrical system, the NOCO NLX31 is the lithium upgrade that does it all — start, run, and recharge — better.
