[RE-wrenches] HUP cell removal

[Ray]

We've used an engine hoist before, but for tight spaces, we built a rig 
out of unistrut with a small block and tackle.  Come along can be hard 
to use, and puts dangerous metal parts over the battery.

HUP batteries are easier to install

I've since gone to a winch system, and also try to move the batteries on 
rollers without taking the cells out.
