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
No Connect
in the Cell Interface - 12 channel model. Pins 2, 4, 6, 8, 10, 11,
12, 13, 14, 15, 16, and 17 are
No Connect
in the Cell Interface - 12V 4 channel model.
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.
