Description
The Universal 12V–84V LCD Battery Capacity & Voltage Monitor is a versatile, high-precision battery management gauge designed to provide real-time telemetry for a wide array of electric vehicles, marine systems, and solar setups. Featuring an adjustable working voltage range covering 12V, 24V, 36V, 48V, 60V, 72V, and 84V configurations, it visually displays precise battery percentage and live voltage on a bright, waterproof-protected green LCD screen.
Equipped with a built-in function button, users can easily toggle between battery capacity, real-time voltage, or turn the display off entirely. It includes an intelligent low-power alarm that flashes when capacity drops below 20%, along with built-in reverse polarity protection. Powered directly by the circuit under test without requiring an external power source, it is ideal for golf carts, RVs, boats, e-bikes, motorcycles, and forklifts.
Note: Not compatible with Lithium Iron Phosphate (LiFePO4) batteries, 1–2 series lithium packs, or packs exceeding 15 series cells. Package includes 1 battery monitor meter.
Key Features
- Wide Working Voltage Range: Highly adaptable monitor that tolerates DC 12V to 84V systems and can be custom-set for 12V, 24V, 36V, 48V, 60V, 72V, or 84V battery banks.
- Intelligent Low-Capacity Alarm: Screen display flashes automatically as a visual warning when remaining battery capacity falls below 20%.
- Bright Green LCD Screen: Crisp liquid crystal display equipped with a PVC waterproof film protector and high-visibility green backlight.
- Multifunctional Toggle Button: Integrated switch allows you to cycle through battery capacity percentage, live real-time voltage, or power the unit completely off.
- Reverse Polarity Protection: Safe circuit design prevents permanent damage if power wires are connected in reverse.
- Ultra-Low Power Consumption: Consumes over 50% less operating power than conventional battery indicators, preserving your pack’s reserve energy.
- Broad Chemistry Compatibility: Supports standard lead-acid and compatible lithium battery banks for visual state-of-charge tracking.
Benefits
- Eliminate Range Anxiety: Accurate percentage and voltage readouts ensure you always know your exact remaining power before heading out.
- Universal Fleet Versatility: A single gauge model adjusts seamlessly across 12V cars all the way up to heavy-duty 84V industrial vehicles and golf carts.
- Weather-Resistant Durability: PVC film front surface provides reliable dust and water resistance for exposed outdoor and marine dashboards.
- Zero External Wiring Needed: Draws operating current directly from the measured battery source for straightforward, plug-and-play installation.
Applications
- Electric Vehicles & Micromobility: Real-time battery monitoring for e-bikes, electric scooters, and motorized bikes.
- Golf Carts & Utility Vehicles: Upgrading dashboard battery indicators on Yamaha, EZGO, and club cars.
- Marine & RV Power Banks: Tracking state-of-charge on backup house batteries, boats, jet skis, and recreational vehicles.
- Industrial & Automotive Equipment: Voltage monitoring for 12V to 84V forklifts, cars, trucks, and specialized DC machinery.
