There is no current pass between the Remote Battery Voltage Sensor and Battery after connected, so a regular cable (less than 1mm2) is enough for collecting the voltage data.

Steps to connect to the RBVS:

1. Find a regular cable (less than 1mm2)

2. Plug one side of the cable into the RBVS Terminal (shown as Remote Voltage Sensor in the picture)

3. Plug the other side of the cable to the Battery

*IMPORTANT: check the label carefully, do NOT reverse connect the positive and negative side on battery, it will cause the RBVS terminal damaged.
