Group 31 - 180Ah Lithium 12V Deep Cycle Battery

Massive Power — With 180Ah / 2,304 Wh you get more runtime, more cycles, and more usable power from every charge. LiFePO4 chemistry delivers up to 95% usable capacity versus 50% from traditional lead-acid — effectively doubling your available power in the same footprint.

Built-In Bluetooth Monitoring — Keep tabs on your battery from your phone with the Ohmmu Energy App. Monitor voltage, state of charge, temperature, and runtime in real time — no guesswork, no surprises. Available on iOS & Android.

Self-Heating Technology — Tested for performance and safety down to -20°F, cold weather is no match for Gen 5. The built-in self-heating system automatically warms the battery during charging in extreme cold conditions, protecting cell integrity and keeping you operational when temperatures drop.

Longevity — With a 10 year warranty and a 6,000 cycle lifespan at 80% depth of discharge, this will power everything for years to come.

Scalable — Install up to 6 in series to create a 72+ Volt system. Or install up to 10 units in parallel to create 1,800Ah system. Drop that lead anchor and upgrade your RV, boat, or other energy storage system, with the ultra light and longest lasting 12V Lithium batteries available.

Sustainability — Lithium batteries last up to 4x longer than lead-acid, meaning fewer replacements, less waste, and fewer batteries ending up in landfills. Their higher efficiency and lighter weight also reduce the energy and resources required to charge, transport, and maintain them over their lifespan.
