Product overview
The Fly-Power 11.1V 4000mAh Lithium-ion polymer battery pack uses a 3S1P arrangement of FLP-705590 cells, with each cell rated at 3.7V and 4000mAh. The pack measures 21.5mm thick × 55.2mm wide × 92.5mm long and weighs approximately 220g. It uses CC/CV charging, 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.
Charging operation spans 0 to 45ºC, while discharging operation spans -20 to 60ºC. At 40–60% charge, storage temperatures range from -20 to 60ºC for less than 30 days, or -20 to 45ºC for less than 90 days. Overcharge detection is set at 4.250±0.050V, with release at 4.150±0.050V. Overdischarge detection is set at 2.75±0.08V, with release at 3.00±0.10V. Discharge overcurrent protection has a 4000mA threshold and a 10.0±5.0mS delay.
