4.4.3. Battery Cells

The Battery Cells connector provides cell voltage input and a means for balancing the cells. The cable
wire should be rated for at least 750mA to survive worse-case current.
Pins 8, 16, 17, and 18 are
12, 13, 14, 15, 16, and 17 are
All unused voltage inputs should be tied to the next highest potential voltage sense input. In this way,
all pins should be connected with the exception of pins 8, 16, 17 and 18 in the Cell Interface - 12
channel model and pins 2, 4, 6, 8, 10, 11, 12, 13, 14, 15, 16, and 17 in the Cell Interface - 12V 4
channel model.
Connect the battery cell voltage sense leads to this connector.
