The CI12 is a Cell voltage and temperature monitoring module with CAN Bus communication and high rate cell balancing. It is used as part of a Battery Management system.
When using and/or installing any BMS is it essential to observe all relevant safety precautions around working with live electrical connections. Especially when connecting directly to cell terminals as is the case when connecting up a cell voltage measurement device. Please seek professional training when working with live cells and/or high voltage batteries. See our Electrical Saftey Guide for some basics.
