Does any one know where I can purchase a replacement or have my 2011 XU battery rebuilt?

How many of them leaf cells could you fit in the original aluminum battery box? I've been interested in this, and from the looks of things you made 5 fit (with the other two under the seat).
Hi ZNRL,
I left everything original (original BMS and original Charger) on the bike except the battery. I had to re-wire the Nissan Leaf battery cells exactly the same way the original zero battery was wired to the bms, so I suggest taking your time marking all the wiring if you change the battery. I am quite happy with the results as bypassing the internal Zero controller or "brain" would have meant more work to rewire everything, more parts to be added and bought, loosing the original display and some safety features.
I would strongly suggest to consider 18650 (or the new standard 20700 if available) cells for an off road bike as you can easily fit them into the original battery box (no engineering/making external or additional battery boxes). I choose Nissan Leaf cells as I live in Canada and I was lucky to find a supplier that would ship the cells to me at reasonable cost. 18650 cells would have doubled my cost for the same capacity but the job would have been cleaner.
Word is that 18650 cells have a much lower discharge rate limit that could be exceeded on a Zero. Anyone following this advice should look into the matter carefully.
