LiFePO4 HHS ENERGY 12 V 300 Ah Battery - Maximum Capacity, Full Control

The LiFePO4 HHS ENERGY 12-volt 300 Ah battery is for users who need a really large but still mobile energy storage. Thanks to its lithium-iron-phosphate chemistry and new Grade A+ cells, the pack provides more than 6,000 duty cycles, a stable 12.8V voltage and a safe 200A discharge current. A built-in Smart BMS with Bluetooth connectivity protects the battery from overcharging, deep discharge, overheating and short-circuiting, while tracking voltage, current and temperature on a mobile app. The compact 345 × 190 × 245 mm housing and 26 kg weight make the HHS ENERGY 300 Ah battery lighter than conventional AGMs with three times longer life - ideal for photovoltaics, campers, boats and emergency power.
