Electrical system design

I've been on the road the past few weeks, so I've been spending time researching all the products I need to consider as part of the system design.  I think I've settled on the main drive motor, speed controller, and battery pack voltage and AH rating.  Below is the current block diagram for the system.

Here is picture of the Warp11HV motor and a link to the spec sheet from the manufacturer.
