Jeeez , coulda fit your battery in the whole on the front of the arm, and kept the clean lines of the oil bag..
One minus is the battery weight is a minus if moving with the arm, but pretty sure you and myself are not worrying about that..
Big Plus is, gets one of the heaviest components, down low, where it should be..lower center of gravity..
I like that arm , here is a pic of mine.. And a pic of the shock mounts before i cut them off.
