Re: Di2 - different lights since firmware upgrade

I've the same problem but worse. My internal battery has been through about 8 charge cycles. Gave it a full charge a week ago and 5 minutes into my first ride, I lost all power. Limped home, gave a full charge, and 10 minutes into the next ride, same problem. I updated my firmware 2 weeks ago and theats when all the trouble started. There's something not right here.
Whole thread available here:http://www.bikeradar.com/forums/viewtop ... t=13074332
I have not been riding my bike, but i suspected something like this would happen.
Battery shows charged and then suddenly it dies after a short ride.
My battery junction box also illuminates green and red at same time.
This guy above, in the copied text, his battery dies after a very short while when he's riding.
So mine dies after a few days and in this time, the bike has not been used at all.
I wonder why this happens with the very latest firmwares installed?
I called Shimano center as mentioned previously. When i did so, i also asked about the differences in the batteries BTR-2 and BTN 110. They told me the battery part is virtually same same.
You just need the latter for blue tooth etc.
So with this in mind it should not be a compatibility issue (due to updates) i guess.
If there was something wrong with the internal wires, should that also mean that the guy at Bikeradar have same problem with his wires?
I checked my bike for moist in any connections, but could find none.
Could it be a derailleur has been damaged?
Anything sucking juice from a battery ough to have a kind of relay signaling when it needs power and when not?
What if such a relay got damaged and signal is constantly on?
I can imagine this happening in any electrical device.
I currently await our local Shimano center dealer to call me for a scheduled time.
Last time i was there, they complained of the fact that Shimano does not pay them anything for the labour hours so they did not help much at all.
Actually, that time i dealt directly with Shimano over here.
That was more easy, since it was no question what was faulty (battery).
This time however, it's more a can of worms.
Came to think about it, Di2/ EPS or Etap won't make you win any races.
But when it works most like it better than mechanical.
Too a point where i am actually been pondering if Rotor with it's UNO groupset is really in such a bad boat after all.
Everyone who's using electronic shifting and has to cancel their rides time after time, i think these might just be the right persons to jump at UNO.
A pity that it cost so much and reports says the FD is shifting rather heavy.
