Here's what I did with mine...
I used quality velcro across the bottom of the chassis and put it on the bottom of my packs. That way you can position them "exactly" where you want and it keeps them from moving...period. Then take your stock hold downs and flip them over and use a couple pieces of two-sided tape.
Here's the most important part...make sure you loctite the 4-40 threaded posts into the battery posts and use 4-40 nylon lock nuts and NOT the blue thumbscrews...they'll come loose immediately!
Here's another tip:
Ditch the blue wheel "kit" locknuts and get yourself some good 8-32 hardware grade locknuts (2 regular...2 low-profile). Yes the blue one's look cool...but they will also come loose during a race and you'll destroy a wheel. The nylon inserts in them are very very weak.
P.S. I charge the pack when it's in the car also.
