This build started with an older BionX PL350 36v kit that found it's way to me. Only 230 miles on the clock, but the battery was stone dead (this is related to how it found it's way to me). I rebuilt the battery, as I often do, with brand new cells. It's now a 13.5Ah battery instead of the stock 9.6Ah battery, so this kit has about 35% more range than it did right from the factory!
I've also successfully demonstrated that one can do pack powered lighting with a BionX conversion - both headlights are powered directly from the main battery!
As always, keep reading for a lot more details & photos.
