XRAY - Model racing cars

The new battery I just got for my T3 is a little thick, and although it is not tight, there is only about half a milimeter clearance between the battery and the top deck. I am concerned whether this lack of space could be a problem, since I know the T3 chassis is designed to 'flex' to certain extent, and half a milimeter may not be enough room for such flex.

Should I be concerned at all, and if this is a problem, what would be the best way to fix it? (Aside from getting rid of the battery, obviously) Should I remove just a tiny bit of material from the upper deck?

Thanks in advance!

Which battery is it? The LRP/Nosram 5900? You may want to file your slots so the battery can sit a little lower allowing more clearance
