Ryobi Double battery wall mount for different size batteries. It holds a 4A and 2A

I really liked the design of these battery holders. They take up less space that most others and don't need space below or above to put in or remove the batteries.
I wanted one that would hold both the smaller battery and the larger battery. I have a few spots where I keep my tools, I like to keep charged battery nearby, one of each depending on what I am doing. I might want light weight or I need the battery to last longer. So I blended the two into one. Shout out to the OP.
