BCR2 Internal Battery question
Moderator: robbosmans
Okay bear with me here. I am running Ultegra 6770 di2 and would like to upgrade to an internal battery.
I understand the normal procedure would be to change the junction box to an ew90 and change the shifter cables. You can then charge the battery using the BCR2 charger through the junction box.
I much prefer the standard 6770 (junction box/shifter cables). Is there any way to keep the front end the same and use the internal battery as well. Will it work? And will I be able to charge it by temporarily plugging in the Ew90 box and charging through that, without the shifters being plugged in?
Thanks for any help

I just researched this for similar reasons. Couldn't find anything that would lead me to believe it would work. The firmware is incompatible.

SuperDave (from Felt) has gotten the EW67 to work that way.

I'd ask Dave what firmware he's running...You may need to be careful not to update. And if your internal battery ships with firmware different than whats on the bike you may be forced to, as the battery won't charge with incompatible firmware on the rest of the system. I had this problem.
