4- BATTERY AND WIRE SELECTION GUIDE
There should be 5 x 12V batteries as energy source for UPSLIFT. Battery charge capacities
should be minimum 4 Ah. However when the batteries are used at the same time as the
energy source by the traction motor, then the current taken from the batteries by the motor
should be taken into account for selecting the charge capacity of the batteries. Table 3.2 shows
the required wire cross sections and battery capacities related to the motor powers.
