Crimp terminal 39-00-0073
Wire gauge range AWG18-24 stranded
This interface is used to connect the current shunt and the (optional) 10k Ω NTC thermistor on the
current shunt to the Battery Controller. The positive operating power is provided in a fused
connection to this connector.

This connection must only be made after all other connections to the Battery
Controller have been made.
Connecting to a Current Shunt
The Battery Controller requires the shunt to be on the high side (positive end) of the battery
stack. The
VSHUNT_REF signal is used to compensate for the voltage drop in the sense wires as well
as to provide the positive reference for measuring the overall voltage of the stack. VSHUNT_BAT and
VSHUNT_LOAD carry the differential voltage measurement from the shunt. VSHUNT_BAT must be closest to
the battery cells and VSHUNT_LOAD must be closest to the Stack Fuse so that the measured current
has the correct polarity. Run all three wires close together to minimize outside interference.
