123SmartBMS Dual Sensor G3 2021
123SmartBMS dual range (up to 500A) current sensor for gen3.
It is possible to use the BMS with one current sensor. This works without any problems. The disadvantage is that you cannot measure charge and discharge currents separately from each other, only the incoming or outgoing current of the battery. Connect the current sensor to “Sensor 1” on the Begin Board and make sure you get a positive number by the current next to the battery image in the app when you charge, and a negative number when you discharge.
