Surprisingly long charge use time.
Fully charged, it kept my BMOC4k running passively for just over 5 hours. That augers well for actual recording time, when comparing with the 35-40 min. of the provided internal battery, which keeps the camera passively powered for just over 60 min. I doubt the more expensive BM recommended external grip is as good bang for buck. The only remaining unknown is the working life of both units.
