Internal Battery Charger / PC linkage device

Non-series components SM-BCR2

This Shimano Battery Charger not only charges internal Di2 batteries such as the BT-DN110 and SM-BTR2, it also doubles as a PC linkage device and lets you update firmware and customise setting.

It can be very useful when restoring a non-responsive Di2 system.

You'll need the Shimano E-tube project software in order to make use of the PC linkage options.
