Shimano BT-DN110-01 Di2 Internal Mount Battery
- 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
- Using a hard wired battery system which is both light weight and accurate compared to current wireless technology (as a wireless system would require 4 batteries: one for the RD, one for the FD, and one for each shift lever)
- The use of a single small and discreet internal battery is light weight, efficient and creates a robust and reliable system
- One charge can give between 1000 and 2000 kilometre range depending on conditions and front mech operation (as this is the main power drain)
- 500 times rechargeable life
- Internal chip enables system wireless functionality of Bluetooth components
- 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 E-tube terminals connection
Mr warrenReally concerned before purchasing this. My drivetrain was 4 years old and the battery had been dying after 100 miles, then stopped taking any charge. Ordered this and it’s fixed the issue, 300 miles since first charge and still showing ‘ solid green light’
Mr SilverthornThe new Di2 battery works really well, best price I found from a reliable source, quick delivery.
Mr HopkinsThe battery this has replaced lasted approx 4 years for me and the bike is used regularly. It comes with new securing washers and circlip, which is good as it is likely you will bend the old one on removal. Retail price is not cheap but if you run Di2 then this is probably to be expected. Merlin's discount makes it easier to swallow.
A AbbotReally small battery that sits easily down the frame or in seat tube. Really easy to install
LeeQuick delivery from Merlin as usual. Battery was brought as an upgrade to DI2 system for the new synchro shifting and to use with the Blutooth phone app, which is does well when paired new d-fly sensor.
d3425634Remarkably light weight. Good battery life, smaller than expected. Offers the synchro-shift functionality which I am a fan of.
