The BG-S4-C Battery Grip from Vello accepts up to two NP-FW50 batteries and effectively doubles the shooting capacity of your Sony a6100, a6300, or a6400 camera, which is especially beneficial when shooting video. Both batteries are rechargeable inside the grip via its built-in USB-C port. An alternate shutter release button allows shooting comfortably while holding the camera vertically, and the rubberized nonslip grip provides secure, enhanced handling. The integrated strap mount enables attaching a hand strap or a shoulder strap. The battery grip mounts easily to the camera body with its 1/4"-20 threaded mount, and a 1/4"-20 tripod mounting socket on the bottom of the grip allows for the use of a tripod, monopod, or quick release set.
Note: This grip is also functionally compatible with the a6500 camera, but because the body is slightly larger, the fit is not ergonomically perfect.
