    have to have it

      The group is battery based... you have to have one of these.

      Buy 2

        Di2 shifting is GREAT ... until you run out of batteries -- then you have a long, hopefully downhill grind home. So don't repeat my mistakes, buy a spare and keep your shifters charged and ready!

        Easy to use and keeps the di2 batteries charged up.

        Unanswered Question

        The chart show two part numbers for chargers. Is this part SM-BCR1 or SM-BCR2? Am I right that there are two different parts depending an on external or internal battery?

        must have

          if you have di2 you have to have it. simple to use.

          love it

          • Familiarity: I've used it several times

          Like that it's not too bulky. easy to charge.

          Quick and reliable

            Admittedly, having to charge your bike is kind of a bummer, but at least Shimano made it easy with the USB compatible charging cable that let's you use any DC adapter you have for other devices (like an iPhone) and use those for your bike as well.

            Works great, but use the right adapter

            • Familiarity: I've used it several times

            Works great, but you must use the correct A/C USB adapter. According to Shimano, it must be rated 5V, and equal to or greater than 1 amp. My wall plug was 500 milliamps (1/2 amp) and it would not fully charge before shutting off. I used an Apple phone charger USB plug which is rated at 1 amp, and it fully charged. Seems like it shouldn't matter, but it does.

            I bought a shimano ultegra 6870 Di2. When I started charging the battery, the charger battery indicated a yellow lignt. After 2 hours the light was off. I thought it was fully charged but when i checked the E-tube Di2, it was still red. Normally, after 1.5 hours, the battery should be fully charged. Please help

            I had a similar problem with partial charging. The box would indicate charge complete, but the indicator light flashed green indicating 50% charge, and it would last only a couple of weeks. After researching the Shimano docs, I found that the A/C adapter you plug this into must be rated 5V, and equal to or greater than 1 Amp. My wall plug was 500 milliamps (1/2 amp). I used an Apple phone charger USB plug which is rated at 1 amp, and it fully charged.

            plug and play

              pretty simple.. plug it in and walk away.

              Great unit.

              • Familiarity: I've put it through the wringer

              All you need to charge your di2 E-tube Cockpit junction box. It also works great to keep your di2 system up to date with the lastest firmware. Just plug it to you bike and your pc, download the lasted Shimano software and follow instructions.

              Does the battery charger come with the USB connecting cable and/or wall outlet connecting cable? If not, is the connecting cable from the power source to the battery charger a standard/universal plug type or is it proprietary?

              Best Answer

              Jeff, it doesn't include the mini USB needed to attach it to the computer or wall. Surprisingly, Shimano doesn't actually make one BUT it is the same charger I use for my GoPro, Camera, and various cellphones.

              good cost, service

                excellent!!

                backcountry, thanks~

                Does this come with the usb charger...

                Does this come with the usb charger cable?

                Yes it does.

                Di2 Reference Guide
                Battery and Wires: Our Shimano Di2 packages are built for three standard configurations based on battery location and wire routing. First, you'll need to determine if your frame uses an internal or external battery mount, and whether the routing is either internal or external. Below is a guide for which battery, charger, mount, and junction boxes are required for your configuration.

                Battery Mounts: The SM-BMR2 battery mount is available in three configurations -- Long External, Short External, and Long Internal. Both Long versions are to be mounted using the bottle cage mounts, while the Short version is designed for Di2-specific frames with either a chainstay or down tube mounting location.

                Junctions: There are two junctions needed for completing your Di2 build -- A and B. Junction A, SM-EW90, is located at the handlebars and available in both three- and five-port options. The three-port option is intended for standard shifting with a left and right hand shifter. If you have the intention of using Shimano's satellite sprint shifters, or a combination of time trial shifters and shifter/brake levers, the five-port junction box will be the necessary selection.

                Depending on your frame specification, Junction B (SM-JC40 or SM-JC41) is located either internally or externally at the bottom bracket area. Accordingly, SM-JC41 is designed for frames with internal wire routing, while SM-JC40 is intended for external wiring options.

                E-Tube Wires: For your convenience, we've created wire packages for your Di2 build kit in the sizes Small, Medium, and Large. Below, you'll find which wire lengths are included in each kit. Additionally, we've recommended a kit size based on your frame size.
