When I installed an electric starter on my 212cc engine, I needed a battery to crank the engine.
So I'm using Milwaukee M18 cordless batteries I have at home.
I needed a hidden box for the battery and adaptor.
I decided to cut a 2.5l peanut tank in half to store the battery,
then mount it on the top tube like a regular fuel tank.
The electrical wiring enters/exits thru two 1" holes in the tank's bottom.
Actually, I sawed 2 tanks in half lengthwise, so each half would have its flange around its perimeter.
Four M5 bolts will secure the tank's halves together.
Despite its size, the battery barely fits in there, because of the tank's sloping feature.
It's so tight, I had to SHAVE the battery's top edge, to clear the tank top.
