After 7 years my LiIon battery pack finally gave up. Everything else works perfectly. I called the bike shop I bought the system from and said that they think I may need a new system, as the new batteries may not be compatable with my older system. I understand the new versions may have slightly better performance, and possibly (can not get a confirmation) smaller battery pack, but I am not really prepared to cough up 1500.00 USD.
Any thoughts on replacing/rebuilding the battery pack?
