6 -The mounting area of the BMS Mini 2 must be protected from mechanical particles (dust, dirt, large objects) and water. The BMS Mini 2 is recommended to be placed close to the cells it controls, but away from high current circuits to reduce interference to measuring circuits and increase overall reliability of installation.
