The SM-BTE81 is the charging adapter for Shimano's BT-EN817 in-tube battery. It sits between the EC-EN814 4A charger and the EW-CP110 charging port, so you can top up the battery without having to pull it out of the frame.

It's a small part, but an important one in the BT-EN817 charging set-up. Worth having as a replacement if the original has gone missing or been damaged. Genuine Shimano STEPS part, built for the brand's second-generation battery management.
