Slash 4x4 battery question
 

I'm about to buy a Turnigy Nano-Tech 3s 5000mah lipo and i'm not sure that the 45-90c will fit. The dimensions the site lists are 10mm too wide for the tray for slash 4x4 but there's a comment saying its only 49mm wide. I was curious if anyone had one or might have heard whether or not this will fit. If it doesn't actually match up to the tray i can downgrade to 25-50c burst its saying 48mm on it.
