Hello, I want to ask a question about the chassis battery height for this Traxxas 4-TEC 2.0 BL-2S Brushless Chassis Roller. I can see the picture showing the battery height is 26mm, is there a option for 23mm? I would much appreciate if you could reply to me soon about this. Best regards Hubert

The battery in the combo is 25mm we do not know of a 23mm from traxxas but other brands can be slimmer.
