Product overview
The Guangpeng Fly-Power 3.7V 120mAh Li-ion polymer battery pack uses an FLP-352025 cell in a 1S1P arrangement. The pack measures 3.8mm × 20.2mm × 27.5mm and weighs approximately 3.2g. Its nominal voltage is 3.7V and its nominal capacity is 120mAh. Charging uses the CC/CV method, with a standard constant current of 0.2C (24mA) and a constant voltage of 4.2V per cell. Maximum continuous discharge current is 120mA, with a discharge cut-off voltage of 2.75V.
Protection parameters include overcharge detection at 4.250±0.050V and release at 4.150±0.050V, plus overdischarge detection at 2.75±0.08V and release at 3.00±0.10V. The overcurrent threshold is 1000mA with a 10.0±5.0mS delay. Operating temperatures are 0–45ºC during charging and -20–60ºC during discharge. At 40–60% charge, storage temperatures are -20–60ºC for less than 30 days or -20–45ºC for less than 90 days.
