Just saw this but yea i was running mc012's > UA5 > jb3. Should have my 481's in a few days so i will be doing some more testing.
Phantom power is on. i can run up to 3 7.2v packs at a time with my current power cable hack and hot swap them at will. I have 4 new 3400mAH packs and 3 1500 packs that are thrashed. I have got 6+ on the old packs and 20+ on 3 of the new packs. I also use Dean's plugs instead of the standard RC pack plugs.
I also have a 4pin cable for any situation that requires a SLA that i have never used in the field.
let me know if you want some better pics
