Good luck with your build, it sounds like a pretty nice one 
I also have a switchblade that I am electrifying, it is a very good deck, your feet feels locked in, without having to use bindings. But there is just one problem with the deck, and that is wheelbite. If you drop the truck through depending on how loose of a setup you prefer, you can have wheelbite even with 90mm wheels, anything above 90mm I recommend top mounting. With the truck you ordered, there is no way you can fit pneumatics, unless you get a wheelbase extender bracket like this:
For the battery I recommend using the P42A cells, and ordering from Acido. He has amazing prices and know how to build good batteries.
Depending on whether you want everything in the enclosure on the bottom, or you willing to fit the ESCs up on the tail of the board, you can get a 12S5P of P42A to fit, if you are interested in the layout for that, let me know and I can search for the picture. Otherwise go for 12S4P. Dont bother with 10S5P, it’s not worth it 
As for the remote, you can use a magnetic micro USB charging plug, like i am using for my VX1. You plug this into the micro USB port:
And it automatically connects if you move the cable close enough, without you ever having to care about the micro USB braking:
Just make sure to get a quality one, some of the cheap ones tend to be loose. This was a little bit more expensive than the entry level ones, about 12€, but I am sure you can get good ones a little cheaper if you want.
I saw this in an old Lee Wright video btw, he’s a legend
