I've been running Di2 for a couple of years now and this was the perfect reason to upgrade to an internally mounted battery. When used with either the 3 port or 5 port e-tube junction it even means you can charge your battery by just plugging the charger into it. Haven't had to charge it since fitting it a couple of months ago so all is looking good
