Get a Grip. The Canon BG-R20EP Battery Grip w/ Ethernet Port attaches to your EOS R5 Mark II to extend shooting times and provide a more secure grip with vertical orientation shots! This battery grip features an atypical Ethernet port that can quickly transfer video and still image files, especially in Dual Shooting mode! Although it can hold two Canon LP-E6P Batteries, it works just fine with one battery. You’re always welcome to add more to your order from that highlighted link! Just like the camera, this grip can withstand the same weather and dust conditions.
