General Specifications

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 12s 19500mAh 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.

Notice: Please do not assemble the battery privately,Parallel charging for two packs of batteries maybe lead to short circuit or ignition.If no otherwise specified, an interval rest time is 30min between charging and discharging.
