Forgive my ignorance if this is a stupid question, but does anyone know what the row of four contacts are on the wireless backplate? I assume that is how the battery charges wirelessly, but why are there four? I would assume it only needs two, a positive and negative, but could it be two positive and two negative?
On the same note, what are the two contacts for towards the top? I thought it may be for the flash since those are on both the normal and wireless, but I'm not sure. Any help would be appreciated.
