Hi n_maher,
Thank you for your concerns.
The SLA battery charger that we use comes stock with the XLR plug. It is a very thick cable and would be pretty hard to mistake it for an interconnect (unless you are carelessly switching cables in a room with poor lighting). I suppose anything is possible. The Isabella comes with a detailed User's Manual and there are just some things in this world that require some level of attention and care - and I suppose this is one of them. If one is very concerned that they will have a problem with this XLR plug/jack battery charging system, perhaps this product is not the best choice for them. It is extremely easy to use and none of our customers have had any problems with this (we use it in our Signature amplifiers and there are a few hundred of them being used around the world).
Regarding the XLR plug on the charger side, the pins are deep inside of the XLR plug's body, and not exposed to any degree to be of concern. If one tries to stick a metal object into the body of this XLR plug, I suppose that would not be very smart. Otherwise, it is no need for any concern and this is not some sort of design blunder from the battery charger manufacturer. In the case that the pins were in fact shorted, the charger goes into protect mode (short circuit protection).
Best regards,
Vinnie
