 2. Multiple protection functions: with overheating, overvoltage, short circuit, wrong connection protection

 3.External temperature sensor: The ambient temperature will affect the parameters for charging the battery. The controller needs to perform parameter compensation according to the temperature of the battery, especially in places with large temperature changes. It is strongly recommended to install a temperature sensor.

Note: Lithium batteries do not require temperature compensation

 4. Lithium battery automatic wake-up function: When the lithium battery BMS is protected for some reason, the controller can automatically wake up the BMS and continue to charge the lithium battery
