For extended shooting and enhanced handling when used in the vertical position, the Battery Grip BG-22 for the EOS R allows two LP-E6N batteries to be used and offers internal battery charging via the USB Power Adapter PD-E1.

Shoot with the EOS R for Longer Periods 
The Battery Grip BG-22 accepts two high capacity lithium-ion LP-E6/LP-E6N batteries, the same as used on Canon's EOS 6D Mark II, EOS 7D Mark II, EOS 5D Mark IV and EOS 5DS/5DS R DSLRs.

Superb Handling when using EOS R in the vertical position 
Experience the same great, intuitive handling when using the EOS R in the vertical position controls duplicated to enable the same operation to be carried out no matter the orientation of the camera.

Can be used to charge two LP-E6N batteries 
A unique feature over this battery grip is the additional facility for it to be used as an external battery charger when plugged into the optional USB Power Adapter PD-E1. Charge your batteries even when the grip is not attached to the camera.

PC Terminal for syncing external studio flash with the EOS R 
A PC terminal is located on the battery grip to allow traditional wired studio flash to be used. By placing the terminal on the grip, space is made available on the EOS R for other connections.
