HPI Low CG Chassis "Were To Mount 5s Lipo?"

[Takedown]

Got a new HPI low cg chassis along with my new savage and I plan onto to convert it. The problem Im having is I can seem to fit my FlightPower 3200mah 5s lipo anywere on the chassis. I have the idea to custom fabricate an upper deck and mount it up their but really dont want to go threw the hassle... I dont want to lount it on the origianl nitro motor plate because the outrunner Im getting has a 53/30 stator and needs all the room it can get. Here is a pic of my savage and its new chassis. Already got a few scratches on it.





Hope you guys can help me out with this...
