A few nights ago I finished the last few parts of my frame structure and also constructed a real battery harness that will sit above the center leg mounting plate.
It will hold 3 standard 12v 7amp batteries in the droid a nice low center of gravity. I’m hoping the design will allow easy access for charging and removal.
The bottom plate is the center foot mount and attaches to frame ring #4.
It’s based on a photo I saw on this site and thought it was a good design to hold the batteries.
