The Ultra Rock Ultra HV Semi Solid-State battery is a Semi Solid-state Li-ion battery series that has a higher discharge current and higher cell voltage compared to a normal solid-state Li-ion battery. The discharge interval of each battery cell is from 2.7v to 4.45v and the discharge rate can be up to 25C. Advantages of battery 7S 77000mah Compared to traditional semi solid-state Li-ion batteries, the Ultra HV Solid-state Li-ion battery has a lightweight and higher energy density. The drone endurance time will be increased by using this model of batteries. In contrast to normal Li-ion batteries, solid-state batteries do not heat during usage even when a high current is being drawn from the battery. They are more resilient to shocks and hits. Battery 7S 77000mah applications Ultra HV Solid-state Li-ion battery is suitable for most UAVs or other electrical equipment that requires a long endurance time: Agriculture drones , Industrial multi-copters, VTOLs , Robots, Surface ships, etc. For a comprehensive reading of related products, please visit the Motionew website.
