Battery in a zen?

[team n.o.m.a.d]

Just fitting my electrics in my gt12 zen and was wondering what stop the battery from moving front to back? Ive noticed holes in chassis do u fix something in front of battery or just use tape?
Cheers

im lucky my speedo fits between the servo and lipo and makes a perfect stop.

But should'nt move if its taped in properly.
