Is my A6500 setup safe?

[Ben Johnson]

Hey guys, first time posting.

I recently upgraded my A6500 rig and finally bought a V-mount battery, along with a D-Tap FW50 dummy battery. However I’ve heard endless rumours and stories of people frying their gear so I just wanted to be safe.

I have 3 questions

1. The INDI PRO D-Tap FW50 dummy battery doesn’t fit perfectly into the battery slot and will fall out unless I force the lid closed. Is this damaging to the cable?

2. The dummy battery is labelled as “Regulated” on the box but then directly beneath it says “WARNING: This cable is unregulated” What’s the situation here?

3. My NEEWER V-mount battery rattles when I shake it, this definitely seems concerning although since it was a cheap Amazon battery I wasn’t sure. Regardless should I get a refund?

Please see Imgur link for details, thank you.
