RCU Forums - Building a Brushless e revo

Hey folks, I just had a quick question. I am building an e revo conversion. Well I guess it's a summit actually, initially I was using the revo 3.3 chassis but realized that the stock transmission was a pain to make it work well so after a ton of money and spontaneous purchases etc I decided to switch everything over to the brand new summit chassis I had. I bought the e revo 2.0 transmission which fits perfectly and put the 3.3 bulkheads on it. So now everything is pretty much almost good to go. I just need to mount the ESC and reciever box and add the battery doors/vents and batteries then I should be ready for a test run. My question is, does anyone know the k c what the exact dimensions of the battery boxes are on the 1/10 Summit/E Revo chassis so I can get batteries that will fit correctly. I have a 6s fat pack and a 4s pack but both are way too big for the battery boxes and there's no room for them anywhere else. TIA
