About 3.8V HV Cells
High-Performance Power | Self-developed | Superior Performance
High-voltage (LiHV) lithium batteries are specialized cells for professional users who want more precise control feel. At the same specification, an LiHV battery typically delivers higher and steadier power output.
However, it requires a compatible ESC and charger — please confirm they support LiHV mode before use.
The table below uses our 3.8V battery as an example to help you select the right one for your FPV.
