BT-DN110-A
Brand: Shimano
Second version of the 11-speed Di2 internal battery, listed by Shimano in its own catalogue column since 2019. Its published figures are exactly those of the BT-DN110: 500 mAh at 7.4 V, 50 g, one E-Tube SD50 port, master unit and firmware updates, charging through the SM-BCR2. Shimano documents no functional difference between the two.
