Product overview
The GEPRC Storm 4S 1050mAh 120C LiPo Battery supplies power for freestyle and racing quadcopters, with toys and boats also listed among its applications. Model number GEP10504S120A identifies a 4S1P pack with 1050mAh capacity, 14.8V nominal voltage and 15.54Wh energy. The supplied configuration consists of one GEPRC Storm 4S1050mAh120C battery. Its physical construction has a flat profile, a smooth surface and welded power cables. The pack measures 25.5 × 38.5 × 76 mm and weighs 137.0g.
Both the charging and discharge connections use XT60 connectors, and the maximum discharge rating is 120C. The charging specification recommends 1C and sets a maximum of 3C, while additional charging guidance recommends 1–1.5C. Recommended chargers are the HOTA D6 PRO, ISDT 608AC and ToolkitRC M6D. Charging requires supervision and a cool, ventilated environment at 0–45°C. A battery that has just been used must be allowed to cool below 45°C before charging, and each LiPo cell must remain at or below 4.2V at full charge.
During discharge, cell voltage must not fall below 3.7V; over-discharge damages the battery and causes swelling. Long-term storage requires 3.80–3.85V per cell, with a charge-discharge activation performed within three months to maintain battery stability. The battery must not be disassembled, reassembled or rewired because of the risk of short circuit and burning. Following a collision during use, remove the pack and inspect both the battery and its connector. A ruptured battery must be disposed of and must not be reused.
