Shimano BT-DN300 Built-In Di2 Compatible Battery IBTDN3001

BT-DN300 is a lithium-ion battery developed by Shimano for Dura-Ace Ultegra and 105 Di2 2x12 bus groups. Like its predecessor, it is mounted internally to the frame, typically on the seat post. It has three connections and powers all electronic components via the slim EW-SD300 power cable (not included): rear derailleur, front derailleur, and two shift/brake levers in a fully wired setup. Unlike previous models, the BT-DN300 does not have its own charging socket, but is charged via the rear derailleur. It's also not Bluetooth enabled. The nominal voltage of the battery is 7.4 volts, the nominal capacity is 500 mAh. A full charge takes up to 1.5 hours if the charging cable is connected to a power supply unit with a USB port, or up to 3 hours if connected to a USB port on a computer. Once charged, change your gears for approx. 1000 km. You can use it throughout. Blind plugs and small parts required for installation are included.
