wheely king 7cell stick pack

[notcrawlin]

Does anyone make a aftermarket battery box that accepts a 7cell stick pack for the wheely king.It almost fits in the stock box but obviously does not close.Yes i could zip-tie it in but i like the look and the convienience of the stock box cover snapping shut . the stock body may not fit with a 7 cell stick but i want a bounty hunter body or hummer body instead any ways. I dont really crawl (i run a 13 turn motor for xtra speed but i am not a speed freak) any ideas!
