RT power systems can be connected in series. The U-BDI communicates with
the individual batteries in the system to enable battery to battery balancing and to gather system
state of charge.
1) Fasten all battery packs in position via means supplied in the vehicle/device.
2) Attach the negative power cable to the negative terminal on the first battery pack (this
pack will have the lowest potential @ 12V).
3) Attach a jumper cable between the positive wire in the first battery pack and the negative
terminal on the second battery pack (note: the jumper cable must be the same gauge wire
as the positive and negative terminal cables).
4) Add additional jumpers to complete the series string as depicted in Figure 4.
5)
Attach the positive cable from the vehicle/device to the positive terminal of the highest
potential battery pack.
