7 segment battery display led
a 7 segment battery display led is an electronic component used to visually indicate the battery level or voltage status in devices such as power banks, portable electronics, and battery chargers. it typically consists of a series of 7-segment led digits arranged to display numeric values, which represent the voltage level or percentage of battery charge.

these displays are known for their clear visibility and low power consumption, making them suitable for battery-operated devices. they are usually controlled by microcontrollers or dedicated ics that measure the battery voltage and convert it into a readable numeric format.
