Thanks for the tip, as others might not realize that and I forgot to say something already.
The battery rack is going to bolt up to those engine mounting points, I don't have a set design for the rack yet, but I plan to make sure it's ridged enough to stiffen the frame, currently trying to figure out how to get some braces to go from the head tube to the rear engine mounts without getting in the way of the batteries, I think if I use some aluminum plate that goes both between the batteries and under them it will be stiff enough as it will create an upside down "T", however I do it I realize it has to act as a stressed member as well, that is however part of why I chose this bike, no cutting of the frame and no welding of the frame, as that is where you create brittle areas that crack later on.
