The batteries in my helmet intercom system died. With my luck Cardo no longer supports the Q2 system and doesn't provide help with new batteries. I found a few articles on the internet about replacement batteries but not sure if the info. is accurate. Does anyone on this site have experience they would share. The only batteries I find on ebay are from countries in Europe. One site recommends an Ipod generation 5 battery as a substitute. Any info. will be appreciated.
