Ok. problem identified and fixed! I took apart the mod to check for physical faults and sure enough I found one. on my vt inbox there is room behind the negative contact. I don't know if theres supposed to be a piece of plastic behind it to hold it in place or if its supposed to be glued but mine is floating free with nothing but pressure holding it in place. when I used an orbtronic battery (long) it caused the negative contact to slide toward the back wall of the mod causing terrible if any contact with the battery. I quickly repositioned said negative contact, put in a sony bat and IT'S ALIVE!
I hope this helps anyone encountering the same problems
