About This

• MEET THE NLX31 — A dual-purpose lithium battery that delivers the starting power of a starter and the deep-cycle capacity of lithium. Outperforms lead-acid with less weight, more power, faster charging, and longer-lasting performance.
• UNMATCHED STARTING PERFORMANCE — Delivers 1,600 amps of peak current - twice that of lead-acid - for effortless starts in any condition. With 200 amps of continuous power, it’s one of the most capable starter batteries ever built.
• PURE DEEP-CYCLE POWER — Get 120 amp-hours of uninterrupted energy with no voltage drop-off. Advanced lithium technology ensures consistent performance and delivers up to 2x the usable capacity of comparable lead-acid batteries.
• PERFECT FIT — Designed for Group 31 drop-in replacement. The quad-post layout supports series or parallel setups - up to 4 batteries - with versatile terminals, including threaded, SAE, and button head, for maximum connection flexibility
• DYNAMIC BMS — Built-in battery management system ensures safety and reliability with bidirectional cell balancing and protection from overcharge, overdischarge, short circuits, and more - plus active thermal monitoring with no resets required..
• FAST CHARGING — Recharge completely in just 2.4 hours with a 50A charge current - 2x faster than lead-acid. Advanced lithium tech delivers blazing-fast speed and unmatched efficiency, taking charging performance to an entirely new level.
• ENGINEERED TO LAST — Built with an engineered plastic shell and reinforced by a honeycomb lattice, it’s made to endure harsh environments—resisting vibration, water, and dust intrusion with an IP65 rating for rugged, lasting performance.
• LONG BATTERY LIFE — Delivers up to 6,000 cycles at 50% depth-of-discharge—lasting 20x longer than lead-acid. With 2,000 cycles at 100% DOD, it offers exceptional lifespan and long-term savings, making it the smarter power investment.
• IN THE BOX — Includes NLX31 120Ah lithium battery, handle, hex key, terminal covers, (2) SAE posts, (2) 3/8-inch posts, (2) 5/16-inch posts, and (2) button head bolts. It also comes with a 5-year warranty and is proudly designed in the USA.
