After extensive reading, I am totally on board a V – mount battery solution for the BMPCC 4K.
v-mount batteries (98W) with TWO d-taps should power the camera and a monitor (specifically SmallHD focus 7).
If I'm running a gimbal I can totally offload the weight on the gimbal or camera with a v- mount waist belt. When I’m on a stick, should be easy to rig the camera and v-mount battery with a passive v mount plate off the rig or tripod. Since there are no batteries needed plugged into the monitor, weight comes off the monitor as well.
So to build that flexibility, I'm considering the following.
SOONWELL B98-V 98Wh 14.8V Lithium-Ion Battery
Cheap passive V mount plate just for rigging the battery off a cage, rails, or waist belt
A dummy battery FOR THE SMALL HD that powers the monitor from the ONE of the D-TAPS on the

4. The OTHER d-tap ON THE BATTERY goes straight to the BMPCC D-TAP port
The BMPCC requires 22 watts when recording raw to external drive. So, I would guess the math is simple. If you have a 98 watt-hour battery, and the camera is drawing 22 watts + the monitor draw of 11 watts = 33 watts. 98/33 gives max almost 3 hours.
I've read these reports concerning issues with powering multiple components from ONE battery. Seems across the industry (BMC, Arri, etc.)

Seems like it’s just a matter of training oneself to plug the POWER taps in first, THEN the HDMI out from the BMPCC to the monitor. You can buy special “isolation” adapters for d-Taps but these seem expensive.
