I've just bought a BMPCC 4K and have been experimenting with a couple of battery solutions.
I bought a Small Rig battery plate for NP-F batteries thinking that this would give me the option of much better battery life. However with 2600mAH NP-F550 batteries, the battery life isn't much longer than the included 2000mAH LP-E6 battery.
Doing a continuous recording at 24fps with BRAW 8:1, recording to SSD with LCD at 100% brightness, I got:
1) included LP-E6 battery: 50m15s
2) "Neewer" 2600mAH NP-F550 battery via Small Rig battery plate to 12V input: 1hr5 minutes
This makes sense from a capacity proportion - about 30% more capacity in the NP-F battery and 30% longer run time.
I was expecting much worse battery life with the LP-E6 battery, having read reports of 20 minute usage life.
I am limited in the size of NP-F battery that I can use on the Small Rig plate due to its position. I have it mounted on top of the cage (on the left side so as not to obscure the camera function buttons), but under the top handle. I can't fit a larger NP-F battery under the top handle, and there aren't any other good options for positioning the battery plate without using rods and mounting the battery behind the screen. Mounting on top right is possible, but makes it hard to reach the record, ISO, WB & shutter angle buttons.
Would I be better off finding higher capacity LP-E6 batteries? I saw some (cheap) 3200mAH batteries advertised, which if correct, would exceed the capacity of the NP-F550.
I could then use larger NP-F batteries mounted on some rods, when I want to rig the camera out more completely (follow-focus would be the next accessory I add, and I need rods for this I think)
Presumably the real run-time of a battery is based on the mAH rating and not the actual type of battery?
