Chassis thoughts... vertical, or horizontal batts

[zeropointbug]

Hey, im almost done designing my new chassis. I was wondering on one thing though...

DISREGARD THIS MESSAGE, measurments were typed in wrong... right measurements on my next reply!

I could have horizontal batts (A123 cells), and make the chassis plate ~240mm wide (also more plate material), or stand the cells on edge close in next to the braces and the total width would be 165mm.

My question is do you think 240mm is too wide? Will this hit the ground if landing at an extreme angle, or bottoming out? The 240mm one will have a lower CG, while weighting in a little more, the 165mm will have higher CG and lighter (not by much). Anyways, like to hear any experience or thoughts about both setups.

BTW, its 5 M1 cells per side, 10 total (700 grams)
