Dc Voltage Display Circle 4.5-100v Dc

The DC 4.5–100V circular digital voltmeter is a compact panel meter used to monitor real-time battery voltage. It fits into standard round 29mm or 30mm panel holes. It is widely used in cars, motorcycles, solar setups, and battery banks. The meter powers itself directly from the source it is testing. This means it requires no external power supply to turn on and read voltages.
