What is the capacity of the battery?

The rear derailleur is 800mAh and the front derailleur is 500mAh, which can realize 20,000 shifts. Usually, for a professional rider who rides 200km per day, the battery can last about 10 days after a single charge; for an average rider who rides 20km per day, the battery can last more than a month after a single charge, depending on the frequency of shifting and other conditions of use.

What type of transmission does EDS use?

It uses a dual transmission system that utilizes both Bluetooth and ANT.

Which brand of cassette does it support?

The app allows you to customize the speed and gear spacing, so in theory, it can support 3-14 speeds cassettes from all brands.

For EDS OX, is it possible to install a double chainring with this rear derailleur?

Unfortunately, due to its direct mount structure, the rear derailleur is only compatible with a single chainring system.
