battery grip for K-3

I see Pentax recommends the BG-5 battery grip for the K-3. what is the difference between the BG-5 and the BG-4? I have a BG-4 from my K-5 and it fits and works fine.

You need to physically modify 2 metal pegs for a BG-4 to work (fit) on the K-3. There are no other differences, though the K-3 may draw more power, so the circuitry in the BG-5 might have been updated.

If you want to attempt the "hack" (at your own risk), here are the instructions:
