Product overview
The Fly Power FLP-042255 is an ultra thin lithium polymer battery pack with a nominal voltage of 3.7V and a nominal capacity of 20mAh. Its maximum dimensions are 0.45mm × 22.2mm × 55.5mm, and it weighs approximately 0.5g. Charging uses the CC/CV method, with a standard constant current of 0.2C (4mA) and a constant voltage of 4.2V per cell. Maximum continuous discharge current is 20mA, with a discharge cutoff voltage of 2.75V.
The pack operates at 0–45ºC during charging and -20–60ºC during discharge. Overdischarge detection is set at 2.75±0.08V, with a release voltage of 3.00±0.10V and a detection delay of 100±50mS. The overcurrent threshold is 500mA, with a delay of 10.0±5.0mS. For storage at 40–60% charge, the ambient temperature range is -20–60ºC for less than 30 days or -20–45ºC for less than 90 days.
