Ultra-low temperature + high current + long life

This series of products can be charged and discharged with high current under the ultra-low temperature of -30℃, and the cycle life under 0.2C current can reach 20,000 times.

It is mainly suitable for electronic devices that work in a low-temperature environment or need to be used in severe cold climates such as the north or the polar regions.

tell respectfullyThis product does not come with a protection board, so it is strongly recommended to use a standard high-quality constant-current and constant-voltage function of the special charger for charging; in order to be safe, remember to charge under supervision, and cut off the power supply immediately after full.

Electrical Characteristics:
Charging current: standard ~0.5C/fast ~1C

Charging time: 0.5C*2.5hrs(standard)/1C*1.2hrs(fast)

Standard charging method: 0.5C constant current (CC) charging to 2.8V/string, then 2.8V/string constant voltage (CV) charging to current less than 0.05C

Maximum charging current*: 5C/1C below 10°C
Continuous discharge current*: 10C/5C below 10°C

Maximum discharge current*: 20C|instantaneous/10C below 10°C

Discharge cutoff voltage: 1.2V/string

Minimum storage voltage: 2.4V/string, otherwise it should be recharged in time.

*Voltage value multiplied by the number of cell strings when connected in series; operating current whichever is the smaller parameter.

Temperature Characterization:
Charge:-30~45°C Discharge:-30~55°C Storage:-30~35°C
Relative humidity: 45~85%
