Product overview
The Guangpeng Fly-Power 7.4V 1800mAh lithium polymer battery pack uses FLP-525068 cells in a 2S1P configuration. Its nominal voltage is 7.4V and nominal capacity is 1800mAh. The pack measures 11.0mm thick, 52.2mm wide and 70.5mm long, with an approximate weight of 73.0g. Charging follows the CC/CV method, with a standard constant current of 0.2C (360mA) and a constant voltage of 4.2V per cell. Maximum continuous discharge current is 1800mA, with a discharge cut-off voltage of 2.75V per cell.
The battery operates at 0–45ºC during charging and -20–60ºC during discharge. Overcharge detection is set at 4.250±0.050V per cell, with release at 4.150±0.050V per cell and a detection delay of 1.0±0.5S. Overdischarge detection is 2.75±0.08V per cell, with release at 3.00±0.10V per cell and a 100±50mS delay. The overcurrent threshold is 4–5A with a 10.0±5.0mS delay. At 40–60% charge, storage temperatures are -20–60ºC for less than 30 days or -20–45ºC for less than 90 days.
