-Adapted multi shifting of RD-6770*The new SM-BTR2 battery and SM-BCR2 charge are available
SM-BTR2 battery is connected via a regular EW-SD50 wire, so all 6770 owners should be able to use it.
Could someone verify that?
The description for the battery states to use the new SM-BCR2 charge only? This seems as an unfriendly move from Shimano, but it needs to be verified wheter this is an actual requirement or is Shimano just trying to make more money.
The good side of SM-BCR2 charge is that the description states:The SM-BCR2 is also an interface for the Shimano E-Tube configuration software.
Which is very good news. If that is indeed correct and you can use it instead pf SM-PCE1
, the price for it is actually very good.
About charging the new SM-BTR2 battery.
As I currently understand, 6770 owners must still remove the SM-BCR2 battery to charge it, as do 9070 owner who have internal Di2 wire installation. The isn't a 5 port junction box for 9070 nor 6770. One option to charge it on the bike is to unplug a component and plug the charge there. Needs to be verified.
The new battery is chargeable on the bike only when you have 9070 with extarl wires and are using SM-EW90-A or SM-EW90-B junction.
