Product overview
The Guangpeng Fly-Power 3.7V 4000mAh polymer Li-ion battery pack uses FLP-554868 3.7V 2000mAh Li-Po cells in a 1S2P configuration. The pack has a nominal voltage of 3.7V and a nominal capacity of 4000mAh. Its dimensions are 11.5mm × 48.5mm × 71.5mm, with an approximate weight of 130.0g. Charging uses the CC/CV method, with a standard constant current of 0.2C (800mA) and a constant voltage of 4.2V per cell.
Maximum continuous discharge current is 4000mA, with a discharge cutoff of 2.75V per cell. Operating temperatures extend from 0 to 45ºC during charging and from -20 to 60ºC during discharge. At 40-60% charge, the pack supports storage at -20 to 60ºC for less than 30 days or -20 to 45ºC for less than 90 days. Overcharge, overdischarge and overcurrent detection each have defined thresholds and delays.
