Product overview
The Fly-Power 3.7V 90mAh Li-ion polymer battery pack uses an FLP-401225 lithium-polymer cell in a 1S1P arrangement. Its nominal voltage is 3.7V and nominal capacity is 90mAh, with dimensions of 4.1mm × 12.2mm × 27.7mm and a weight of approximately 3.0g. Charging uses the CC/CV method, with a standard constant current of 0.2C (18mA) and a constant voltage of 4.2V per cell. Maximum continuous discharge current is 90mA, with a discharge cut-off voltage of 2.75V.
The pack has an overcharge detection threshold of 4.250±0.050V and an overdischarge detection threshold of 2.75±0.08V. Its overcurrent threshold is 140mA with a delay of 10.0±5.0mS. Charging operates from 0 to 45ºC, while discharging operates from -20 to 60ºC. At 40–60% charge, the storage ambient temperature range is -20 to 60ºC for less than 30 days, or -20 to 45ºC for less than 90 days.
