u/ihave3apples - if you want something less expensive, you can attach a $19.99 NP-F single battery plate to a $13.99 P&C pistol grip with a $5.99 1/4"-20 double male screw and plug it into the battery compartment with a $16.99 LP-E6 dummy, as seen here.
This setup would cost you less than $57 - while allowing you to use batteries as large as the 7800mah NP-F970, instead of the two small 2800mah NP-F550s in the Blackmagic grip.
Hope this is helpful!
