If you have it connected to one receiver battery, you still have the 2nd pack to power the servos.

Just my 2cents of course but cosmetical issues should never outweigh safety.

I need to confirm to be 100% sure with Richard, but there is a servo short/overload function built into the adapter to protect against this. It shuts down the output port and maintains a live signal. I am testing on the output of the last adapter in the segment. If this does work properly, it may actually be the most reliable, as it should eliminate the potential of the battery to overload. Below is a snip from the Royal SRS manual.

However, until now there has always been one drawback: if a short-circuit occurs in one servo, this blocks the bus lead, and all the servos connected to it stop working. Here at PowerBox-Systems we have now completely eliminated this former disadvantage: The servo distributors which we have developed are protected against short-circuits in the power supply wires and the signal wire! This means that if one output is shorted out at a servo distributor, that output is switched off within a few micro-seconds, and the bus lead remains active. This supplementary feature is very important to flight safety, since a servo bus without it is not suitable for use in valuable model aircraft!
