Frame Spacer Modification
First, remove all four screws that connect the upper and lower frames. You then use a spacer the length you'll need to fit your bigger battery. Remember to add a little length to the spacers to compensate for the main gear screw, so it doesn't touch the battery. For spacers you can use hollow aluminum tubing cut to the right lengths, several nuts or even cut lengths of a pencil and hollow out the lead from inside. You'll have to get some longer screws or use nuts and bolts and remember to use a threadlocker like "Loctite" on them.
