BMPCC 6K - External battery bank

PostTue Jun 30, 2020 6:49 pm

1. Have anyone tried this External battery bank, or similar one:

2. Is the External Power In socket and wiring the same in BMPCC 4K and 6K?

Thanks, however NPF batteries don't have 12V, so what's the catch?

There are many battery solutions out there but the rigging and setups are pretty odd. Most of them will have some cautionary statement from user experience. I've been using the Core Edge solution which is fine with my own cautionary statement from experience as posted in this thread:

viewtopic.php?f=2&t=114244&p=629719&hilit=core+edge#p629719

Then other than the BMD Battery grip solution, there is a knock off version for $50 that seem to last close to 3 hours reported in this thread:

For P6K 50Wh battery probably not too effective and you need at least 100Wh V-Mount brick to power camera for few hours. But i still can offer 18650 battery enclosure. it was designed specially for BMMCC, but same time works well with any other device

All similar battery plates just upconvert 7.4V to 12V. This is not too efficient because DC-DC step-up voltage converters waste huge amount of power. Also due tiny size wattage output usually very limited. Components may became hot. there is no any info about max wattage output in specs, but it may be not enough to power 6K camera.

yes this is stepup votage, but you can power your
pocket for a minimum of 2 to 2 1/2 hours with one NP-F970
when it is coming from baxxter (10500 mAh) or so, and not from sony
and one of the battery costs only 45 dollar
