Battery

Accepts standard 18650 lithium-ion battery. Includes USB charging.

Operation without a battery is also supported.

You can insert a standard 18650 flat-top unprotected 3.6V lithium-ion battery like the following:

The NanoVNA V2 Plus4 includes on-board battery protection and charging circuitry and can charge the battery from USB. See here for how to insert the battery.

After inserting the battery, you need to plug in USB power at least once to activate the battery management IC.
