I have an a7 with Sony VG-C1EM battery grip which worked great for about 6 months but now loses power angling the camera down or just bumping it when turned to portrait. I put tape on the back of the batteries to make them more snug but that made the cam not power up at all. Im not sure which of the 4 contacts are shifting during movement. When I return to using a single battery in the camera without the grip it has no issues whatsoever.
I purchased the grip from Bestbuy about a year ago for $248 so I would like to get at least a few years out of it if not much longer.
Any experience with this issue and any solutions that have been discovered?
Greatly appreciate any help in advance
