The Autel EVO II Intelligent Battery is a 7,100mAH rechargeable lithium polymer 3S battery. This battery provides up to 40 minutes of flight in forward motion, and about 35 minutes in a hover. Autel's patented Battlock system on the EVO II guards against accidental battery ejections either during high-speed maneuvers or hard landings, because they happen to even the best of us.
It takes about 70-90 minutes to charge a single EVO II Battery on the standard wall charger. You can also charge multiple batteries. When charging all four batteries on the charging hub it will take about 5.5 hours to full charge all batteries on the hub.
Advexure also offers a rapid battery charger for the EVO II Battery.
