SmallRig VB155 Reviews

Connecting 3 devices straight from the battery

By Jerry
Rated 5 out of 5
Date: 2026-02-24

This battery is pretty cool. I have my canon c80 connected with a D-tap to DC cable; an external monitor connected with a 12v DC cable; and my zoom H6 recorder connected with a USB-A cable. 3 devices all connected to one battery. I ran all 3 devices for about 10 minutes just to make sure the battery could handle the power draw and it did. I have the battery mounted on a smallrig v-mount plate which is attached to a smallrig Canon C80 cage.

SmallRig Battery is my go to

I use the 155's with my Red Komodo exclusively. I normally can get a run time of 6-8 hours on a run and gun day and for more produced shoots (interviews, or stylized b-roll) it can last all day. I am using this to power the camera and an external transmission system. Just two batteries will guarantee I have power all day for the cameras.
