so, i opened her up and saw 5 SLCs total.
the first shot is a bit blurry, but there 12v 20Ah. doing the math, they must have 4 wired in series and 1 in parallel? i'll look closer at how they're wired later, to double check.
here's the controller, alarm, and DC-DC converter - stuffed under the seat. it's all held down by zip ties, so for now i can't check the other size (or rear) of the controller to see what it is. it does seem long though, which matches the images kelly has on their site.
