Hey everyone - I’m working on my first ever DIY electric skateboard. I have decided to go hub motors because I like being able to coast with little rolling resistance. I am going dual hubs because I am 6’2" 195lbs. My main reason for this board is to get my my house to the caltrain, and then from the caltrain to work in San Fransico. There is a medium hill on the route I take which I would love to get up, but I could take a flat route instead if need be. So I dont need to really go very fast or very far.
Here is a list of my parts. I have a few questions at the bottom I was hoping to get some help with.

Questions: Ok so batteries. Should I just sack up and buy the enertion battery pack? If so which one? I would be very happy with 20mph and 7mile range. Would their 6S2P ok? I obviously would like to keep cost as low as I can, but I dont want to skimp out and regret it either. The 6S2P pack (comes with charger) isnt too much more expensive than 2 batteries from hobbyking, and a charger. If I really need to get one of there more expensive packs, I would need to think more about it.
If I end up getting battery packs from hobby king can I cut the pack open to get the batteries to lie flat? Also, Jacob’s hub motors site doesn’t seem to have a recommendation for batteries. Right now I am spec’d for 8S 5000mah.
Are there any other wires / random pieces I am missing?
