4.9.3 Preparing the battery for connection to the BCM

Battery cells are not connected to the BCM directly. 56/PR02 resistors are inserted
between BCM and the cells to clear any fault that would arise if a battery cell lead were
shorted. The resistors are mounted as near as possible to the battery terminal in order to
protect as much of the wiring as possible. A typical connection is shown Figure 4.9.
The M6 ring lug (depending on type of battery) is screwed onto the cell terminals. The
other end of the wire is screwed onto the 5.0mm pitch screw terminals. Details on how the
cells connect to the BCM board are discussed in later sections.
