Re: Joe Sommer/Anvilus [TANKS]

I had some questions about the Anvilus controllers, but following this 
thread answered most of them for me...

If I understand correctly now, the coil circuit which powers the SSRs and 
the onboard electornics of the Anvilus Controller is completely separate 
from the 12v circuit used for the motors....  so I can have three separate 
circuits in my tank, one 12v for the motors, one for the gun elevation, 
rotation, trigger, and one for the RC controller and speed controller.... am 
I correct?

It sounds like its more complicated than it needs to be, but I'd like to 
incorporate safetys for each system as well as having them run on 
independent circuits so everything doesn't shut down when the motors drain 
the main 12v battery.

It also states that the same 12v battery powering the motors can power the 
coil... is there a minimum voltage for this?   like can I use one of those 
7.2v Nicad battery packs used in ordinary RC cars or build my own battery 
receptacle and have 4 AA batteries powering this?
