12V–72V LED Battery Voltmeter – Stop Guessing and Know Your Charge
Are you tired of being caught out with a dead battery because your vehicle’s built-in gauge is unreliable? This LED battery voltmeter provides a real-time, accurate reading of your remaining charge across 8 clear stages, from 10% to 100%. Simply connect it, and the device automatically detects your system voltage (12V, 24V, 48V, 60V, or 72V) for instant, plug-and-play operation with no configuration required.
Note: This device is designed exclusively for direct current (DC) systems. Please verify your system voltage before installation. Compatible with Li-ion, LiFePO4, SLA/AGM, and other standard battery types.
Why choose this model? (Key Benefits):
- Automatic Voltage Detection – Intelligently recognises 12V, 24V, 48V, 60V, or 72V systems without the need for manual settings.
- 8-Stage Resolution (10%–100%) – Provides a granular view of your battery level, allowing you to make informed decisions on the go.
- ±1% Precision – High-accuracy measurements to help prevent accidental battery depletion.
- Low Power Consumption (5–15 mA) – Designed to be energy-efficient so it won’t drain your battery.
- Waterproof Design – Robust construction suitable for outdoor use on e-scooters, e-bikes, tractors, and more.
- Universal Compatibility – Ideal for cars, motorcycles, electric bikes, scooters, solar panels, and agricultural machinery.
Performance and Design
This indicator is crafted from durable, high-quality plastic with a compact footprint of 56.6 × 32.6 × 27 mm, making it easy to mount discreetly on any dashboard or equipment panel. The vibrant blue LED display ensures excellent visibility in both direct sunlight and at night. With an operating temperature range of –10°C to +65°C, it is built to perform reliably in any season. The 8-level indicator (10%, 25%, 40%, 50%, 60%, 75%, 90%, 100%) gives you a clear, continuous picture of your battery status, eliminating any uncertainty about your remaining range.
