Hi Gordy,
I haven't yet altered any of the modules themselves. I have a few projects to finish up before I start altering the modules. It isn't that it will take long it is just that I have zero time.
Yes I do have both the battery powered UcDs and the AC rectified ones running but the AC amp needs some more work to rid of RF hash. My house is an RF magnet. I can't use any unshielded cables at all.
The battery modules I have running are using Elnas Cerafines followed by Nichicon KG followed by some Jantzen bypasses. I also want to try out a snubber as the hotrod thread at diyaudio seems to give lots of props to the solution. I'd also like to experiment with a choke input supply. But first things first.
About the charging, currently I manually plug the battery packs in when I want them to charge and unplug them when I want to run off the batteries. The problem is when I move the amp and unplug the tether between the amp and the packs. When I plug the tether back in when the packs are fully charged, I get a small pop and the output protection on the packs clicks over and I have to plug them back in to reset. I can only imagine that the caps in the amp pull too much too fast.
