3.3

Short circuit protection

Auto cutoff load when short circuit

Connect the positive and negative of this battery pack through a lead with 0.1Ω resistance.

3.4

Cycle life @DOD100%

≥2000 cycles

After Normal charge,discharge @0.33C current to the end of discharge voltage. Repeat above process until discharge capacity reduce to 80% of initial value.

Remain capacity

≥96%

After normal charge, store the battery @25±5℃ for 28days, then discharge capacity @0.33C,the retention capacity accord with criterion.
3.7Communication functionBluetoothCustomized Bluetooth APP
3.8Heating functionHeating when charging under low temperatureHeating on conditions:
1. Below the low temperature charging protection value -2 ° C.
2. Temperature is more than -30 ° C (the lowest temperature allowed to open the heating film)
Meet the above two conditions to open the heating.
Stop heating conditions:
1. Stop heating when above the heating termination temperature.
2. Stop heating when in the discharge state.
3. In the low temperature protection state, heating should be stopped when heating is for more than one hour or so.
 

4.Circuit Protection

The batteries are supplied with a LiFePO4 Battery Management System (BMS)that can monitor and optimized each single prismatic cell during charge & discharge, to protect the battery pack overcharge, over discharge, short circuit. Overall, the BMS helps to ensure safe and accurate running.
