Reddit mentions of SMALLRIG Battery Plate for Sony F970 F550 w/Dc Cable - 752

I've had great success with the Anker 2nd Gen Astro Pro. At 15000mAh, it's truly an all-day battery. And it should be, as 15000mAh is nearly 19 times the stock battery, and over 12 x the Wasabi Power EN-EL20 aftermarket batteries that I also use. Upon receiving the Anker, I ran the BMPCC for a 7-hour bench test before deciding "that's good enough", and turning it off to go to bed - ha! I've also taken it on several shoots, and never had to worry about how long I left the camera on. The only fiddly bit is that you still need to rely on a a non-locking barrel connector (I had previously wired up my own adapter from parts), and that doesn't make for the most reliable connection. But, if you keep an internal batt in the cam at all times, you're protected.

The Anker's also big and flat, making it less than optimal for rigging. I used it at the back of a DIY run-n-gun rig, but I'd like to have a smaller option for more stripped-down scenarios.

I had a few Sony NP-F style batteries, and hoped that at 7.4v they might run the BMPCC with an inexpensive battery plate, but no such luck. If you want to use NP batts, which are a great, small form factor, you need a battery holder that steps up the voltage to 12v. Ikan makes one they charge up the nose for.

u/AndoNeo - here's what you would need to build a rig like this (with US & Australian links, where available):

• Mounting plate: $40USD SmallRig 1775 Camera Mounting Plate ($32.64AUD)
  
• Shoulder pad is the $55USD (on sale in the US) Kamerar Shoulder/Chest Hybrid Pad ($69.99USD to the rest of the world)
  
• Grip is a $13.99 Photography & Cinema Pistol Grip (unbranded version $7.59AUD)
  
• Rods are $12.99 SmallRig 1251 20cm (8") 15mm black rails ($14.69AUD)
  
• The shoe on top of the camera is a $6.99 SmallRig 1241 cold shoe adapter ($5.61AUD)
  
• Samsung T5 SSD mount is a $6.59 SmallRig 761 cold shoe swivel mount ($5.26AUD) plus a $7.40 tripod adapter for small smartphones ($8.70AUD)
  
• Power comes from a $13.99 SmallRig 752 NP-F Battery Plate ($14.69AUD) attached to the pistol grip with a $5.99 SmallRig 828 1/4"-20 double male screw ($4.65AUD) and plugged into the camera with a $24.99 Kondor Blue 5.5mmx2.5mm to Weipu power adapter cable (unbranded version $22.60AUD)
  
• You'll also need at least two NP-F batteries (to power the camera and the light) and a dual charger ($34.99AUD)
  
• Light is the F&V R-300 SE ring light ($358.79AUD) with an F&V 15mm rail mount
  
• SSD is the 500GB Samsung T5 ($149AUD)
  
  This entire setup - with batteries and charger (but without the SSD and the ring light) - costs about $215USD - $30 less than the price of a Blackmagic BMPCC 4K Battery Grip with no batteries.
  
  Hope this is helpful!

I have had good luck with the following items. I am getting around 4 hours out of it.
