Shimano BT-DN300 Di2 rechargeable battery

Di2 battery for internal assembly

The new DN300 battery has the same waterproof design that has been popular with Di2 customers for years. Now with 3 connections, it delivers stable performance for the 12-speed racing bike front derailleurs and rear derailleurs from Shimano (if a fully wired version is selected).

With the same dimensions as the previous model, the flat DN300 battery can be integrated into the seat post or frame to ensure a clear look. Now with 3 connections, the DN300 simplifies cable routing to the front derailleur and rear derailleur and offers continuous performance at all times. The third connection is for those who want to keep the option of a wired version of Shimano's 12-speed Di2 systems open.

Highlights

• Compatible with the new, thinner SD300 power cables that are used from the R9250 / R8150 series
• 3 x SD300 connections
• Same mounting method as BT-DN110 (internal)
