Every lithium ion battery system consists of several single cells, one master unit and at
least one slave unit. Every slave unit can control 4 up to 12 single cells, and the master unit
can control up to 32 slave units and up to 384 cells. For batteries with more than 12 cells at
least two slave units are needed.
