My battery holder ver.4.0 with 4-wire connection support

Hi guys. It's been a long time i didn't post here and here i'm back
All this time i was thinking on making a new holder for my tests and eventually i've designed and made one which i'm ready to show you. Here it is - my holder version 4.0.

All your thoughts are precious for me so don't hesitate to leave them in comments either here or under the video.
