Digital Battery Voltmeter 12V–84V Charge Level Indicator

Monitor Your Battery at a Glance

This compact digital voltmeter and battery charge level indicator gives you a real-time dual readout — both the current voltage and remaining capacity percentage — on a bright 0.56" LED display. Whether you're maintaining an electric bike, car, solar storage setup, or DIY power project, this meter makes it easy to stay on top of your battery's health without any guesswork.

Compatible with a wide range of battery types including lead-acid, lithium, polymer, and nickel-metal hydride batteries across 12V, 24V, 36V, 48V, 60V, 72V, and 84V systems. The meter head automatically recognises the voltage and capacity level — no manual calibration required.

Frequently Asked Questions

Q: Is this digital battery voltage meter compatible with lithium battery packs?

A: Yes! This voltmeter is fully compatible with lithium, polymer, nickel-metal hydride, and lead-acid battery packs. It works across a broad voltage range — 12V, 24V, 36V, 48V, 60V, 72V, and 84V — depending on the model variant you select. Simply connect the two wires directly to your battery terminals for an instant reading.

Q: What does the dual display show?

A: The upper section features an 8-bar LED graph displaying the estimated remaining charge level (from 10% to 100%), while the lower section shows the exact real-time voltage reading with decimal precision. This makes it easy to monitor battery status at a glance on electric bikes, scooters, cars, and DIY power projects.

Q: Does this voltmeter have reverse connection protection?

A: Yes. The meter includes built-in reverse connection protection, meaning accidental reverse wiring will not damage the unit. It's a simple two-wire system — just connect and read, no additional power source or complex wiring required.

Q: What is the mounting size for panel installation?

A: The meter body measures 48 × 29 × 26 mm, and the panel cutout (mounting hole) required is 46 × 27 mm, making it easy to install into a dashboard, enclosure, or custom panel.
