A lightsaber can be charged in-hilt or with an external battery charger, depending on the type of lightsaber and model. For in-hilt charging such as the RGB and some Proffie sabers, there’s no need to remove the battery of the hilt as there is a charging port where you can directly charge the saber with a charging cable. With Proffie sabers, the battery is removed from the hilt by unthreading the pommel. The battery is then charged with an external charger that is included in the saber kit.
