Voltage indicator, display, voltmeter 10V-100V

The compact digital voltmeter displays 10-100 V DC voltage in real time. Perfect for e-bikes, scooters, battery systems, controllers and DIY projects where a quick and clear voltage indication is needed.

Key benefits

• Wide measuring range: 10-100 V DC – one module for many systems.
• Clear display: easy scanning in the workshop and in the field.
• Quick installation: simple connection to the power circuit.
• Diagnostics and safety: helps you monitor battery status and voltage drops.

Specifications

• Measuring voltage: 10-100 V DC
• Display: digital display (voltage V)
• Suitable for 12 V / 24 V / 36 V / 48 V / 60 V / 72 V / 84 V class systems*
• Installation: dashboard integration or wired indicator

* If your system is close to the limit (e.g. 100 V), check the voltage of the fully charged battery (e.g. 22s Li-ion ≈ 92.4 V) to stay within the measurement range.

Installation tips

• Observe polarity (＋ / -).
• Connect directly to the circuit to be measured or via the measurement point of the controller.
• Avoid long, unshielded wires in noisy environments; use a suitable cross-section of wires.
• If necessary, add a fuse and input filtering (capacitor) to reduce noise.

FAQ

Is it suitable for 72-84 V systems (e.g. 20-22s Li-ion)?
Yes – it is important that the fully charged voltage remains ≤ 100 V.

Does it measure alternating voltage (AC)?
No – this indicator is for direct current (DC).
