I have the stand-alone CA and the application doesn't have a practical way to install a battery switch between the battery pack and the CA. Are there any special considerations to adding a small switch to the CA's case for the V+ lead so I can power the CA on and off? I assume V+ is the correct lead.
While I don't understand your application, it is a reaaaaaalllly good idea to have a power switch and fuse/breaker between your battery and the load... The CA also uses very little current.
That said, no reason you can't cut the line to put a switch on V+. Check ebikes.ca CA FAQ where Justin discusses splicing etc:

Better yet, email the wizard (Justin) directly and ask tell him what you want to do. As the creator, he should have a better idea of the impact than most of us here.
