The RB-10 does not include a voltage regulator, so you need to connect batteries or a regulator that can handle your servos and receivers. Power sources are connected to input BATT1 and BATT2. You can power the RB-10 from a single source (plug into BATT1 or BATT2) or from two sources (plug into BATT1 and BATT2). For the protection to function properly, it is important that both sources can be loaded with a minimum of 15 A and a peak of 40 A. Never connect more than one servo to the output.
The S.Port from the RB-10 can be plugged into the end of a sensor array or use a Y cable to connect it.
If the sources have the same voltage, it is drawn from both sources. If it is not, it is preferably taken from a source with a higher voltage and the sources are isolated from each other.
You can use any sources (different numbers of cells, different types of batteries and capacities).
