Group 24 LiFePO4 Battery 12V 100Ah, Lightweight 21.9lb Lithium Battery with 100A BMS, 4S4P Expandable, Up to 15,000 Cycles, Ideal for RV, Marine, Solar, Off-Grid, Trolling Motor, DIY Power

• 【Long-Lasting Power – Up to 15,000 Cycles】 Built with premium Grade A+ LiFePO4 cells, this 12.8V 100Ah battery supports up to 15,000 deep cycles at 60% DOD — delivering 10x the lifespan of traditional lead-acid options. Reliable for 10+ years of worry-free use in RVs, boats, solar setups, and more.
• 【100A BMS & Enhanced Multi-Layer Protection】 Equipped with a built-in 100A smart BMS, it provides comprehensive protection against overcharge, over-discharge, overcurrent, short circuit, and high voltage. Reinforced with moisture, dust, and salt-spray resistance for harsh conditions.
• 【Modular 4S4P Expansion – Scalable Energy】 Connect up to 4 batteries in series or parallel for a powerful system of 51.2V 400Ah / 20.48kWh. Scalable design makes it ideal for expanding solar banks, RV upgrades, camper vans, or full off-grid living.
• 【Compact Group 24 Size – 50% Lighter】 Weighing just 21.9lb, this lithium battery fits standard Group 24 battery boxes and is over 50% lighter than its lead-acid counterparts. Great for mobile setups where weight and space matter: boats, RVs, trolling motors, campers.
• 【Your All-Purpose Energy Source】 Power a wide range of devices — from CPAP machines (up to 42 hours), fridges (17+ hours), to lighting, inverters, or emergency gear. Perfect for solar storage, marine life, off-grid cabins, or DIY battery projects.
• 【Certified Safety, Smart Use Tips & 5-Year Peace of Mind】 Certified by UN38.3, IEC, CE, UL, and RoHS for top-level safety and reliability. Important reminders: · Not for engine starting or high-current surge applications · Do not submerge the battery in water · Avoid overloading beyond rated capacity Now upgraded with a 5-year warranty and 10-year repair service — feel free to contact us via Amazon if you have any issues.
• 【First Use & Charging Notice】 1.To protect battery health, some units may ship in 0V protection mode. Use a 14.6V LiFePO₄ activation charger to wake it up before charging (e.g., 14.6V 8A charger with 0V function). 2.Avoid using 12V chargers, standard lead-acid chargers, or automotive chargers. Chargers with repair, pulse, or desulfation modes designed for lead-acid batteries may interfere with the LiFePO₄ BMS and trigger early protection shutdown.
• 3.Before connecting batteries in series, ensure each battery is fully charged and the voltage difference does not exceed 0.2V (fully charged ≥14V). 4.To maintain battery health, charge at least once every 2–3 months if not in use. 5.When connecting multiple batteries, use the same model and age; for best balance, fully charge each battery individually before series connection. ✅ Using a LiFePO₄-compatible charger helps extend battery life and ensures reliable, safe performance.
