Product overview
The FLYPOWER 7.4V 4500mAh Li-ion polymer battery pack(2S of FLP-5567100) is built with 3.7V 4500mAh FLP-5567100 cells in a 2S configuration. The pack measures 12mm × 68.2mm × 103.5mm and weighs approximately 170.0g. It uses CC/CV charging, with a standard constant charge current of 0.2C(900mA), a constant charge voltage of 4.2V/Cell and a charge cut off current of 100mA. Maximum continuous discharge current is 4500mA, with a discharge cut off voltage of 2.75V/cell.
The charging temperature range is 0 ~ 45ºC, while discharging operates at -20 ~ 60ºC. Overcharge detection and release voltages are 4.250±0.050V and 4.150±0.050V. Overdischarge detection is 2.75±0.08V, with release at 3.00±0.10V and a detection delay of 100±50mS. Discharge overcurrent parameters are 6-8A with a 10.0±5.0mS delay. At 40-60% charge, storage temperatures are -20~60ºC for less than 30 days and -20~45ºC for less than 90 days.
