As some of you may know, I am building an electric Vespa. The following thread is me working through it, hopefully with some knowledgeable help from here.
I am starting with this:

I started out going down the restore path, then I bought an ebike, and found forums like this.
Currently I am here:

Lots of work to this point, but still could go stock, but the bug has bitten.
I have a substantial initial list, with the help of Allen:
• QS 205 10 inch hub motor 72v 4000W

• Battery is 72v 24.5 Ah rectangle from Em3EV (Allen's) Shape 195 x 230 x 140mm, or 7.7 x 9 x 5.5 inches

I have two issues that I need to address before I move on. First the battery. I could go with home built, but not sure I have the knowledge to do it myself. This is what I have so far:

I could also use Allen's (195 x 230 x 140mm, or 7.7 x 9 x 5.5 inches) but am hoping for more Amp Hours. Suggestions for a vendor?
The other problem is, the vespa swingarm is part of the motor, and I need a standard-ish swingarm to connect my Vespa to my motor.

Something like this shape, but tubular off a regular MC or scooter.
I'll post my progress, but would love some more input!
Thanks,
