Get's the job done

    For anyone who hasn't tried it, Di2 is life changing. It makes shifting perfect even when you're under heavy load and really shouldn't be doing it. Obviously the battery is a critical component of Di2 and I've found that it holds charge very well, going dozens of hours of riding between charges.

    small and light

    • Familiarity: I've used it several times

    this thing is about the size of two ballpoint pens, smaller than I expected. works great. I shift a ton, so charge around every 750 miles.

    Isn't technology great!

    I remember the Niterider batteries that weighed 2 tons and took up a whole bottle cage... This thing is far more compact and powerful.

    Have had multiple Di2 bikes and the new internal battery has been flawless. No issues to report and easy to use and install. My only minor issue I raise would be an internal mechanism that would a universal support/attach and dampen the unit in the frame. A good shop mechanic can work around this though.

    Invisible Power!

    • Familiarity: I've used it once or twice and have initial impressions

    Just had this battery installed on my bike, and I love that it is tucked neatly into the seat post! From everything I've read and word of mouth from other users this thing is rad!!! Long and reliable battery life. Can't wait to put it through its paces!

    It occurred to me how crazy Di2 is, as I was running a firmware update on my bicycle. When Skynet takes over we Electronic Shifting cyclists are in trouble.

    All Jokes aside though. 1600 miles on this drivetrain and not a single issue or adjustment needed. Every shift has been flawless, and barring any unforseen circumstances, like a crash or some good old fashioned garage or transportation mishap, I fully expect go 6000+ miles with no issues. The only drawback I can find, and this is totally a personal preference, but I sort of miss the mechanical drivetrain for no reason other than the simplicity of pushing a lever which pulls a cable which moves a derailleur. I would argue that the Di2 lacks tactile feedback when shifting, but that is just me nitpicking. I rode the battery until it completely died just to see what would happen. At about 1300 miles (this includes plenty of playing with the new group, shifting just to hear the sounds and show off the auto trim) The battery died on my 18 mile commute to work one morning, first the front derailleur refused to shift, after a few more shift button clicks it did shift down into the small ring, and I had about 30+ shifts of the rear derailleur before the system became unresponsive. So 1300 miles, I think it is safe to say a rider would need to be quite negligent to run out of power on accident.

    How does this battery compare with the previous version of the internal Di2 battery (i.e., the SM-BTR2)? Specifically: 1) is it electronically compatible with the Shimano 9070 groupset; and 2) does it have the same external dimensions such that it is compatible with a seat post battery holder that already works with the SM-BTR2?

    1) Yes, it is fully compatible with 9070 and 6870 groupsets. It adds synchronized shifting capabilities, which the BTR2 does not allow.

    2) Yes
