Product overview
The Guangpeng Fly-Power FLP-042255 is an ultra-thin lithium-ion polymer battery rated at 3.7V and 20mAh. Its maximum dimensions are 0.45mm thick × 22.5mm wide × 55.5mm high, with a weight of approximately 0.5g. It uses CC/CV charging, with a standard charging current of 0.2C (4mA) and a charging voltage of 4.2V per cell. The recommended maximum continuous discharge current is 20mA, and the discharge cutoff voltage is 2.75V.
Protection parameters cover overcharge, overdischarge and discharge overcurrent. Overcharge protection operates at 4.250±0.050V, with recovery at 4.150±0.050V. Overdischarge protection operates at 2.75±0.08V, with recovery at 3.00±0.10V and a delay of 100±50mS. Discharge overcurrent protection is 100-200mA with a 10.0±5.0mS delay. Charging is permitted at 0–45ºC and discharging at -20–60ºC. Storage temperatures are -20–60ºC for less than one month or -20–45ºC for less than three months.
