Whilst I think of it- a few people on TABR drowned their di2 chargers, wrap it up well in a plastic ziplock bag!
Also I've always had really good life out of my Di2 battery but had to charge up every second day a couple of times on TABR on some particularly lumpy sections of Missouri/Kentucky when I was constantly shifting. I wasn't alone in this. James at the Newton bike shop reckons that the latest batteries aren't as good as the earlier ones. I managed to charge as I rode via my USB charger, so wasn't an issue but worth bearing in mind.
