Shop name:Chong Qing Shuo Yue Ke Ji You Xian Gong Si NOTE: For instructions on heating cables,the green 5PIN cable of the heating cable needs to be linked to the heating pad, and the rest of the black and red cables are linked to the smart charger(after the smart charger links the BMS,it detects the temperature of the battery through the BMS,which automatically monitors the charging status of the battery) Heat Function interface of heating function:Battery temperature is low temperature charge protection, turn off charging, turn on heating. Cryogenic charge protection is a parameter that can be set within APP The heating power depends on the battery voltage and the resistance value of the heating film. Battery voltage U. Heating resistance R. Power equals U*R Heating current I=R; The maximum I (current) of the board design is 3A. MAX heating power 200W(100W OF B2A8S20P).
