The Sony battery packs a good amount of power into its small size. The much larger Nikon D810 battery offers 1.8X the milli-amp-hour capacity.
Nikon EN-EL15: 7.0V X 1900 mAh = 13300 mAh
Sony NP-FW50: 7.2V X 1020 mAh = 7344 mAh
Based on mAh ratings, the Sony A7R II shooter will need twice the number of batteries as with a Nikon D810. For your author, that means three batteries, four to play it safe, more if shooting video, doing long exposures in the cold, etc.
