This series of batteries are mainly suitable for remote control cars/rail cars/toy tanks and other car models, remote control boats/hovercrafts/speedboats and other boat models, as well as some catapult children's toys and early learning learning supplies, power tools and so on.

To:This series of power battery has high energy and does not come with protection plate, so it is strongly recommended to use a standard high quality special charger with constant current and constant voltage function 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 ~0.1C/fast ~0.5C

Charging time: 0.1C*15hrs(standard)/0.5C*2.5hrs(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

Discharge cutoff voltage: 3.3V/string | 2.75V/string at normal magnification

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%
