I'm pretty sure we have this all figured out, but I thought I'd poll guys here and see if there was any valuable input.

FYI, I have a bit of a Frankenrig including:

PRO Upper J Box
XCS 2" Telescoping post with PRO connectors
XCS Gimbal
MK-V Nexus battery base w/ both AB & V mount battery mounts

Here's my problem. Although MK-V told me the Nexus base would be completely PRO compatible, not so. The AUX power on the PRO upper J Box is not hot, and MK-V had no fix for me. This becomes problematic when you try to power a Genesis (or F35) with the VTR on board. I don't normally carry the VTR, but for the occasional off speed shot.

Phil Cremer of Panavision Toronto has a mod that solves this problem. The idea is to route the 3rd battery directly into the Nexus base & connect it to the post cable's AUX power lines that are currently unused. Since I don't plan on buying an AR, we were going to swap out the 5 pin AR connector (on the front of the Nexus battery base) for a 4 pin battery connector. When I'm shooting Genesis, I simply plug that 3rd battery into this spare battery input on the Nexus base, and boom, the AUX power is now fed directly from the 3rd battery. I use a normal Genesis PRO Y power cable, and problem solved.

I know it sounds pretty straight forward. If anyone has a thought on why this might be a bad idea, I'd love to hear your reasons. Also, if anyone has already done this mod (or other ones with Phil Cremer), it'd be great to hear about your results.
