GoPro 10 attached to the GoPro Volta without a battery inside the GoPro This video is to show/demonstrate that the GoPro 10 can be used without a battery whilst it's attached to the Volta grip Look at the top right corner and you'll see it says NO BATT This is handy as it prevents overheating issues The trade-off is that you will lose some recording time without also having the battery inside but it's worth it to not have any overheating issues I also use Lexar 128GB and Sandisk Extreme Pro 128GB micro sd cards NEVER/DO NOT use Sandisk Ultra cards as they will NOT work properly due to the weak/slow speeds
