My racing bike has the original Di2 gear shifter system. The Di2 system no longer works and I needed a new external battery to see if this was the problem. I couldn’t purchase the battery from all the bike stores that I went to in Sydney, so it was great to obtain it from eBay. The price was good and I obtained it quickly, in about a week. Unfortunately the battery wasn’t the issue but at least I have eliminated that item and now focus on other possibilities.

Changing gears is a lot smoother now with a new battery

It is the only battery available. I found that it was very expensive
