The Think Tank Photo Pro DSLR Battery Holder (Black with Gray Interior) holds two pro-size DSLR batteries in two separate pockets. The ballistic nylon holder folds in half for easy storage within your gear bag and will also fold flat when empty.

I think all TT products are on the pricey side but somehow I still buy them. This one does what it is supposed to do. I most like that it keeps the protective cover in place and protects the contacts to the battery pack.
