1. The heating function is achieved by detect the battery temperature, combined with low temperature protection during charging, the status of the charger to achieve electricity Pool heating control function 2. Not all BMSs support the connection heating function, only BMSs with "Heat" in their models support the connection heating function 3. The heating interface requires an external heating film or charger. The green cable is connect to the heating film, and the red and black cables are connect to the charger. The maximum heating power is 3A, and the maximum heating voltage is 100V 4. Heating on condition: 1. The battery temperature is lower than the low-temperature protection temperature for charge; 2. By connect the heating film for heating, the APP will activate heating, which will consume battery power; 3. Heat through the charger, this is related to the protection board hardware and charger. Please place an order first Confirm the technical status 5. Interface Function Description: 1. Temperature sensor interface: All models of JK BMS are equipped with. 2. RS485 interface: All models of JK BMS are configured with. 3. LCD interface: All models of JK BMS are equipped with. 4. CAN interface: Only configurations with"CAN" in the model. 5. Heating interface: Only configured with "Heat" in the model BMS operating instructions: 1. Download Bluetooth APP from mobile phone. Download method: Search for "JIKONG BMS" in the app store 2. Connect the BMS and battery pack. Ensure that the last cable is connected to the positive terminal of the battery. Before starting, the total voltage of the battery pack must be greater than 20V. 3. Use the LCD activation button or start switch to activate the BMS 4. Ensure that your phone's Bluetooth is turned on, then open the app, click on the top left corner of the app to search for devices, click on the device name, and enter the default password:1234 5. The first startup requires parameter settings and a password. The default para
