Product overview
The GEPRC Storm 4S 1400mAh 120C Lipo Battery supplies power for freestyle and racing quadcopters, with toys and boats also listed as applications. Model number GEP14004S120A identifies a LiPo pack with a 4S1P configuration, 1400mAh capacity, 14.8V nominal voltage and 20.72Wh energy. Its flat exterior has a smooth surface and welded power cables. For installation planning, the battery measures 29 × 38.5 × 76mm and weighs 156.0g. Both charge and discharge connections are XT60, and the supplied configuration contains one battery.
The maximum discharge rating is 120C. The charging specification recommends 1C and permits up to 3C, while additional charging guidance recommends 1–1.5C. Charge only in a cool, ventilated environment at 0–45°C, and allow a recently used battery to cool below 45°C before charging. Charging must remain attended. The LiPo full-charge limit is 4.2V per cell, and discharge must not take a cell below 3.7V because over-discharge can cause damage and swelling. Long-term storage requires 3.80V–3.85V per cell, with a charge-discharge activation performed within three months.
