SIDESHIFT INSTALLATION GUIDE V1.9
If you use a parallel configuration, the two batteries must be identical: same rating
and same manufacturer and ideally new batteries, or at least operated as a pair for
their entire service life. Each battery must be charged separately before installing to
ensure they start at the same charge level. Batteries which are dissimilar in any way
may not charge and discharge equally, leaving one battery undercharged.
To connect two batteries in parallel, prepare two shunt cables of the same gauge
used to connect the batteries to the motor controller. Connect the positive post of
one battery to the positive post of the other and the negative post of one battery to
the negative post of the other.
One post will share two compression terminals: the shunt and the cable to the motor
controller.
24 VOLT BATTERIES
24 volt batteries are less common than 12 volt batteries. You may find it more
convenient and less expensive to use two 12V batteries in series. If required, you
can use four batteries, with two sets of series-connected batteries in parallel to
supply the required CCA.

To connect two batteries in series, connect the negative post of one battery to the
positive post of another using a short piece of battery cable of the same gauge used
to connect the batteries to the motor controller. The two remaining posts are each
connected to the motor controller using two battery cables, supplying 24V.
