BMCC Solution for power supply

Hello together,
After a long while I finally got my BMCC,
Now I'm searching for a cheap solution for the power supply.
Therefore it is difficult to work with V-Mount Batteries, I also have a Canon 5d mark 2 with the Canon LP-6 batteries
Is is a good idea to use them, which adapter is the right one?
How did you solve this "problem", what do you think would be the best and cheapest solution?
