Not too complex. If I had used the same chemistry cells, replacing would have been a cinch. Since the A123 cells have a different voltage profile, I changed the series/parallel configuration. I wanted to learn a bit about Li packs and just used this as an excuse to mess around.
I also learned a bit about ordering cells, pre-welded, from Hong Kong suppliers on eBay. Anyway, it was fun and educational.
I hope you get a lot of use out of your BionX e-bike. They're still the slickest design out there IMO. With 48V, the accel should elicit a nice EV grin, something you're already familiar with!
