My nVision 2s 4500mAh LiPos won't fit Tamiya TA-02SW chassis, because the battery is too long (the original battery brace can't be attached). Therefore I made my own battery brace.
Use the second part as a pattern to drill the holes according to your battery, first with a 2.5mm, then a 5mm drill (or use two 2.5mm drills instead :-) ).
