I thought I was done with the big projects for this ERBE but apparently not. I received two 4S 5800 mah Turnigys a couple days ago but since I'm seriously thinking of going back to the stock chassis, I won't be able to use them. I saw a few people cut their chassis and make bigger battery compartments so I'm giving it a try. I wanted the compartments to extend down instead of up, to lower the CG. So I ordered this,

And I will cut these shapes from that PVC angle.
This part will be folded at each end to form the battery box. I should be able to make the bends by heating the PVC a bit.
The box will be secured to the chassis with 5 M4 flat head screws in counter sunk holes. (in the pic, it is just held there with servo tape) Plastic welding would be cool here but I don't know if PVC can be welded to Nylon. And I never got that plastic welder anyway.
The battery door slides in the slots and a body clip holds the top part to the door on the body post I put there in a previous mod I did for the stock battery doors.
Here's the 5800 mah 4S battery in there, it fits with a few millimeters to spare. I shook the chassis in every which way very hard and even though the mock up is only made of cardboard, the heavy battery stayed in there.
