Little update.
Found a video on YT about a good dirtbike battery (non-starter)... Well, turns out I work with the kid everyday.

Anyway, 2 years later, these batteries are still going strong and stay charged for months. I was sold.
Here I have made my own Test Prototypes. 3 ten cell 2.5Ah 12v batteries

Wired in parallel, 7.5 Ah for any emergency lighting situations. Weighs only 19 oz. in total.

Bird's nesting it in the hood.

Doesn't look too bad.

So, I am waiting for my headlights and the final modifications to this hood before I paint it.
I am waiting for my Regulator Rectifier so I can operate the bike (slight chance of a headlight ticket) around town during daylight hours.
