CONNECTING THE DS2726 EVALUATION KIT BOARD
Figure 1. CONNECTION DIAGRAM FOR DS2726EVKIT+
V10 to V0 are voltage sense lines for the individual cells. For a 10-cell battery pack connect V10 to the positive
terminal of the pack. V9 will be connected to the positive terminal of the next cell and so on down to the last cell. V0
connects to the negative terminal of the battery pack. These connections are for voltage sense and cell balancing
only. The maximum amount of current they will sink is 200mA during cell balancing. The load current does not flow
through these connections. For a connection diagram of a battery pack with less than 10 cells, see Figure 1.
The BATT+ connection should be connected to the positive terminal of the battery pack. The path from PACK+ to
BATT+ is your charge and discharge current path. High currents will flow through this path therefore a heavy gauge
wire should be used.
BATT- should be connected to the negative terminal of the battery pack. VSS is the return current path for the load.
