UBA Accessories - Channel Combiner
Single UBA
The channel combiner allows you to combine both channels of the UBA doubling the charge and discharge current
and power. To do this, connect the battery positive terminal to both positive battery inputs and the battery negative
terminal to the negative battery input (the negative battery inputs are already wired together).
The Channel Combiner makes this easy to do. Plug one end of the channel combiner into either positive input (red) on
the front of the UBA and the other end into the other positive input. The battery to be tested is then connected to one
of the negative (black) inputs (it does not matter which one) and to the banana input on the channel combiner. See
diagram below.
Figure 36: Using the UBA Channel Combiner.
Two or More UBAs
Combine the channels of two or more UBAs the same as you combine the channels on one UBA, but in addition to
connecting the positive inputs in parallel you have to connect the negative inputs between the UBAs. If you don't do
this then battery current will flow through the serial cable and the power supply lines.
Software Instructions
Once you've physically connected the channels in parallel you have to set up a “virtual UBA” that controls these
combined channels. The virtual UBA acts as if it's a single channel, but with higher current and power limits plus some
additional features.
