r0adrunner Posted May 22, 2017 Share Hi Guys I'm looking for a bit of advice; I've got an "old" 10 speed Ultegra Di2 groupset which has an external battery but I have the new Giant TCR frame which does not have anywhere to hold the external battery, it can only support the new generation internal Di2 battery. I am sure someone out there has made this work!? Any comment will be appreciated Link to comment Share on other sites More sharing options...
Butterbean Posted May 22, 2017 Share Doesn't the old mount have an option for extending down the down tube using the bottle cage bolts? Link to comment Share on other sites More sharing options...
Butterbean Posted May 22, 2017 Share http://www.wiggle.co.uk/shimano-dura-ace-9070ultegra-6770-di2-battery-mount/ Like this. I'm sure someone in SA will have one somewhere. Or you could 3D print maybe? Link to comment Share on other sites More sharing options...
shaper Posted May 23, 2017 Share You can get them on ebay if you cannot find locally http://www.ebay.com/sch/i.html?_from=R40&_trksid=p2380057.m570.l1313.TR0.TRC0.H0.Xdi2+external+batter+mount.TRS1&_nkw=di2+external+batter+mount&_sacat=0 Link to comment Share on other sites More sharing options...

r0adrunner Posted May 23, 2017 Share Hi Friends I believe my LBS looked into this option, but there was an issue with getting the wire into frame? Not quite sure? Appreciated the responses! Link to comment Share on other sites More sharing options...
shaper Posted May 24, 2017 Share Hi Friends I believe my LBS looked into this option, but there was an issue with getting the wire into frame? Not quite sure? Appreciated the responses!Drill the front derailleur hole slightly bigger so that you can run 2 Di2 cables into the frame, the battery cable to the junction box beneath the BB and the FD cable back from the junction box Spoke101 1 Link to comment Share on other sites More sharing options...
Skinnyone Posted May 24, 2017 Share Hi Friends I believe my LBS looked into this option, but there was an issue with getting the wire into frame? Not quite sure? Appreciated the responses!True this... So option 2, purchase an internal battery and wiring kit? Link to comment Share on other sites More sharing options...
tdsewell Posted April 10, 2018 Share hi Road runner.... busy going through the same process, did you manage to find a solution that worked for you? any response would be greatly appreciated Link to comment Share on other sites More sharing options...
Cat2forLife Posted April 10, 2018 Share Nothing a drill can't fix. Hope the frame is out of warranty. Issue with replacing the wiring kit and battery for internal version is that the 1st gen (and therefor 10spd) Di2 has different port/ ends than the newer internal wires.
