Hi! So as a first AC myself it’s a little worrisome that some of that gear is out of the umbrella of expertise for your AC, there really isn’t anything here I would consider “specialized gear” so without wanting to throw anybody’s name on the line I might start reaching out to other AC’s that would also be willing to jump on the prep or at least has solid answers for your gear based inquiries.
Also as an AC it’s so important for me to hammer home the importance of a good camera prep, this is where you find out if all of your gear can talk, write, shoot, heck even turn on- there’s a reason most preps are done over the course of a day or at the least a half day, I get that Adorama isn’t renting the camera body but I’d still consider asking if you can prep there (a lot of places will do this and just charge you a prep fee).
Given your concerns with the package going out it seems doubly worrisome that it really isn’t getting prepped either, now let’s get to the important stuff which are your questions:
I'm worried about the camera potentially shutting down while hot swapping as it will drop to 90W momentarily
As long as the mini has ~11.2 volts going into the body with that aks setup you’re good, the drop off can be substantial when you pull one brick off but it usually leaves you in the low 12s assuming you’re not waiting until the last minute to change batts, as long as you don’t walk around in the middle of a hotswap and get a coffee you’ll probably be fine, and sharkfins are for hot swapping so battery changes should be expeditious anyway. The last thing I’ll say is that 90w batteries aren’t small but aren’t huge either and can drain pretty fast on a fully rigged camera so maybe ask your agent for some 150s
I am planning on running my small hd monitors from their own goldmount batteries (they come w/ gold mount plates), but wasn't sure if I'd also be able to power my teradeks simultaneously using the dtap
I’m assuming these are handheld as I didn’t see a size so yes, your batteries (I’d use the hyperslims on monitor obviously) will totally be able to power the teradek rx, that’s what the d taps are there for- obviously as you increase the draw battery power goes down but you won’t overdraw and short or anything.
As for your questions about motor/lens setup this is where the beauty of the prep comes in, you’re right in wondering if the bus cable on the wcu is long enough as my biggest gripe with the wcu system is lack of cable length/angle options and you should definitely check it out before you leave. Also your gear list has no mention of support that I saw so I assume you have that squared away but always good to check. Good luck with your shoot, and if you’re in LA and need a first AC for anything feel free to reach out.
