2-Pack 12V 100Ah LiFePO4 Battery, Deep Cycle Lithium Battery, Group 24 Size, Built-in 100A BMS, 15000+ Cycles, Ideal for RV, Solar, Marine, Trolling Motor, Off-Grid

• 【DUAL RV HOUSE BATTERIES – BALANCED & RELIABLE】 This 2-pack 12V 100Ah LiFePO4 battery set is designed for RV house power systems requiring longer runtime and balanced performance. Each battery operates independently, providing stable and consistent energy for RV appliances and onboard electronics.
• 【2× 100A BMS – SAFE FOR SERIES & PARALLEL USE】 Each battery includes an independent 100A BMS with full protection against electrical and thermal risks. Supports series and parallel connections for expanded RV power setups when properly installed.
• 【GROUP 24 DROP-IN DESIGN – EASY INSTALLATION】 At just 21.9 lb per battery, this lithium solution dramatically reduces weight compared to lead-acid batteries. Standard Group 24 dimensions fit most RV battery compartments with no modification needed.
• 【LITHIUM UPGRADE FOR 12V VEHICLE BATTERIES】 Ditch the acid, leaks, and heavy maintenance. These LiFePO4 batteries are the perfect plug-and-play replacement for 12V lead-acid batteries used in solar rigs, off-grid trailers, boats, and RV backup systems.
• 【DIY POWER EXPANDABLE – FROM TROLLING TO BACKUP POWER】 Supports series & parallel connections (up to 4S4P) to scale capacity up to 20.48kWh. Suitable for powering trolling motors (30–70lb thrust), car fridges, CPAPs, backup vehicle power banks, and more.
• 【Wide Operating Temperature – Reliable in Harsh Conditions】 Designed for outdoor and mobile setups, each battery operates safely from -20°C to 60°C (-4°F to 140°F), ensuring stable performance in extreme heat or cold. The built-in BMS offers temperature protection to prevent damage from overheating or freezing. At altitudes below 2000m, discharge temperatures can reach up to 70°C (158°F). For best results, store at 21–25°C (70–77°F) during off-season.
• 【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 directly 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 smart charger helps extend battery life and ensures reliable, safe performance.
