A rough test of the record time and battery life time on a Blackmagic HyperDeck Shuttle 2 and a Blackmagic Cinema Camera. Both cameras recorded ProRes 4:2:2 1080p 29.97. The batteries lasted close to the times stated in the specifications. The HyperDeck Shuttle recorded for one hour before the battery died. The Cinema Camera lasted just a little over 1.5 hours. The Cinema Camera was also on for about 10 minutes during setup.
