Cell Connections
In order for the system to successfully measure, monitor and balance each individual cell
in the battery pack, the cells must be properly connected to the BMS.
Cell Chemistry and Voltages
Table 3, below, shows the expected output voltage available for the load, at different
States of Charge, for different cell arrangements and chemistry. Each of these values can
be adjusted in the BMS configuration to different operating/charge conditions.

Connecting the cells
A 16-pin connector is used for the necessary monitoring and balancing connections. The
drawings in Figures 6-8, below, show how to connect 6 to 10 cell packs on the BMS1040,
and 11 to 15 cells packs on the BMS 1060.
