Electronic Shimano Di2 gears must be connected to the battery and charged during initial assembly. Find out how it works for Shimano Di2 11-speed shifting systems here.
This tutorial describes the connection and charging process for fully wired Di2 systems (11-speed, wired). For other shifting systems, go to the overview and select the right model.
Step 1: Connecting the battery
The battery is located in the seat post for Di2 11-speed gears and must be connected with a cable in the seat tube.
To do this, attach the Di2 tool to the plug head and insert it into the holder on the Di2 battery. Then remove the Di2 tool.
Step 2: Fitting the seat post
Slide the seat post into the seat tube. Make sure that the zip tie is not pinched in the process.
Position the seat post at the correct seat height and secure it using the clamp screw.
Finally, tighten the screw to the required torque using the torque wrench.
Step 3: Charging the battery
Remove the protective cap from the charging port at the handlebar end.
Connect the charging cable to the charging port and plug the mains plug into a socket.
The charging process starts and is indicated by coloured LEDs on the power supply and the handlebar plug.
Allow the battery to charge fully and do not forget to place the protective plug on the charging port after disconnecting the mains adapter.
