Renogy Lithium Iron Phosphate Battery 12 Volt 50 Ah RNG-BATT-LFP-12-50-US


【4 Times Longer Lifespan】 Offering a lifespan of 2000 cycles (roughly 5-year lifespan at daily use) at 80% DOD, Renogy 12V 50Ah LiFePO4 battery could last 4X longer than conventional lead-acid batteries.
【Powerful Output】 Renogy 12V 50Ah LiFePO4 battery provides a maximum of 640Wh power output, which is 2 to 3 times more powerful comparing to most lead-acid batteries in the same size.
【High Discharging Performance】 The battery provides a maximum of 50Ah continuous discharge current to power most home appliances. The superior lithium-iron-phosphate technology ensures stable battery capacity and performance even under extreme temperatures from -4℉ (-20℃) to 140℉ (60℃).
【Safe and Reliable】 The built-in Battery Management System (BMS) provides over-charge/discharge, over-current, high temperatures, and short-circuiting protection. The fully-sealed housing prevents acid leakage and corrosion and ensures simple maintenance.
【50% Lighter 】 Weighing only 14.7 lbs, this LiFePO4 battery is smaller, lighter, and at the same time delivers more power than conventional lead-acid batteries. The reduced weight makes it easy to carry and install.
