The new DN300 battery features the same waterproof design that Di2 users have loved for generations. Now with 3 ports, it delivers stable power to Shimano's 12-speed road derailleurs and shifters (if a fully wired option is selected).

With the same size as its predecessor, the slim DN300 battery can be housed inside seat posts or frames ensuring a clean aesthetic. Now with 3 ports, the DN300 simplifies wiring to front and rear derailleurs, supplying stable power at all times. The third port is for riders who seek the redundancy of Shimano's 12-speed Di2 wired option.
  • The power house of Shimano Di2 is a long-life 7.4V Li-Ion battery that is both compact and reliable; taking shifting effort away from you
  • Excellent sealing and reliability have been proven through repeated field tests in various riding conditions; including extreme temperatures; rain; mud; and cobble stone roads
  • The use of a single small and discreet internal battery is light weight; efficient and creates a robust and reliable system

  • Battery is to be mounted with seatpost or frame/fork manufactures hardware normally inside the seatpost or seat tube/fork steerer
  • Reliable and secure water resistant SD300 E-tube terminals connection
