How should i mount my battery?

[A RC Dude]

Here are some pics. It was a 5s 5,000mah pack for my e-maxx but it had a bad cell so I got the cell removed and the pack re-wired to be a 10,000mah 7.4v batt for my rustler. Here is how it fits right now:



Now I just need to secure it down to the chasse. I'm thinking that it'd be best to take my e-maxx's old gorilla straps and run then diagonally across the battery. Would there be a better way to do it?

p.s. i know my car is messy as heck with all the wires
