I believe they have mentioned in previous interviews that it has a 6S 18650 lithium ion battery pack (Sony cells), and that instantaneous hover wattage is expected to be around 220W. Since the batteries are also used to keep it warm a large portion of total Wh capacity are reserved for heating, each flight can only be brief before sitting and charging from the pv cells for a day or two.
