Shimano Di2 BT-DN110-A Internal Battery Info
The Shimano Di2 BT-DN110-A Internal Battery sits inside your frame or seatpost and keeps your electronic shifting running — this is the battery unit itself, without mounting hardware, cables, or a charger.
Compatibility matters here. The BT-DN110-A works with Shimano's E-Tube Di2 systems — it is not compatible with first-generation Di2 setups that predate the E-Tube architecture. You'll need a separate EW-SD50 wire to connect it to your Di2 network, and a compatible charger to keep it topped up. When the charge runs low, your junction box will flag a warning before you lose shifting function — front derailleur drops out first, giving you a clear signal to plug in before the system shuts down fully.

- Compatibility: Shimano E-Tube Di2 systems (not compatible with first-generation Di2)
