Product overview
The Fly Power FLP-503048 lithium-polymer battery pack combines a 1S1P configuration with a nominal voltage of 3.7V and a nominal capacity of 720mAh. The pack measures 5.1mm × 30.2mm × 50.5mm and weighs approximately 14.5g. It uses CC/CV charging, with a standard constant charge current of 0.2C (144mA) and a constant charge voltage of 4.2V per cell. Maximum continuous discharge current is 720mA, and the discharge cutoff voltage is 2.75V.
Charging operation spans 0–45ºC, while discharge operation spans -20–60ºC. Overcharge detection and release voltages are 4.250±0.050V and 4.150±0.050V respectively. Overdischarge detection is 2.75±0.08V, with release at 3.00±0.10V and a detection delay of 100±50mS. The discharge overcurrent threshold is 1000mA, with a delay of 10.0±5.0mS. At 40–60% charge, storage temperatures are -20–60ºC for less than 30 days or -20–45ºC for less than 90 days.
