Square Lithium-ion Battery Packs
This series of products with protection board, with the function of preventing overcharging, over-discharging, over-current, short-circuit and so on. It is mainly applied to monitor, alarm, heater, banknote counter, mobile backup power, amplifier, navigator (GPS), LED lights, toys and other electronic devices.
Electrical Characteristics:
Charging current: standard ~0.1C/fast ~0.2C
Charging time: 0.1C*15hrs(standard)/0.2C*7.5hrs(fast)
Standard charging method: 0.1C constant current (CC) charging to 4.2V/string, then 4.2V/string constant voltage (CV) charging to current less than 0.01C.
Maximum charging current: 0.5C / 0.2C below 20°C
Continuous discharge current: 0.5C / 0.1C below 10°C
Maximum discharge current: 1C / 0.2C below 10°C
Discharge cutoff voltage: 2.75V/string
Minimum storage voltage: 3.7V/string, otherwise it should be recharged in a timely manner.
*Voltage value multiplied by the number of cell strings when connected in series/current multiplied by the number of cell parallels when connected in parallel; operating current whichever is the smaller parameter.
Temperature Characterization:
Charge: 10~45℃ Discharge: -10~55℃ Storage: 0~25℃
Relative humidity: 45~85%
