Has anyone run across anything like a dummy battery for v-mounts? I have v-mount sleds, and dummy batteries for my gear, but sometimes, just sometimes, I'd like to run on AC power instead of batteries. By putting a dummy v-mount, AC powered, I could run my cameras all day long without worrying about swapping batteries.

It's not a big deal, but I'd like the option... if one exists! Can anyone help here?

Is this what you mean?

There is a thread on that other forum about this but I couldn't actually find it. Sorry.
HTH Patrick.
