Linkstyle Battery Voltage Gauge 2-Pack — LED Voltmeter for 12V/24V Vehicles, Waterproof Touch Switch

The Linkstyle 2PCS Battery Voltage Gauge is a compact, waterproof LED voltmeter that displays DC voltage and battery percentage for 12V/24V systems with a touch switch and built-in protection.

Designed for cars, motorcycles, RVs, boats and utility vehicles, this dual-function meter continuously monitors battery condition in real time. It reads DC voltages from 5–48V with ±0.1V accuracy and shows power as a 0–100% estimate. The slim, splashproof housing fits into a 30mm panel hole or mounts by screwing the faceplate in place, making it simple to add clean, visible battery monitoring to dashboards and control panels.

How does the gauge display both voltage and battery percentage?

The meter alternates between showing the numeric DC voltage and a calculated battery percentage using an onboard conversion. Use the touch-sensitive control to switch displays or to turn the unit off to avoid draining the battery when the vehicle is stored.

• Voltage range: DC 5–48V with ±0.1V accuracy
• Battery percentage: 0–100% with ±0.1% resolution
• Touch switch toggles modes or powers down the display
• Clear LED readout for day and night visibility

What safety and protection features are included?

This voltmeter is built with multiple protections to safeguard the device and the vehicle electrical system. An internal 10A fuse prevents overloads and excessive current, and reverse-connection protection helps avoid damage from wiring errors.

• Integrated 10A fuse for overload and short-circuit protection
• Reverse polarity protection to prevent burnout from incorrect wiring
• Durable construction designed for vehicle electrical environments
• Water-resistant front face suitable for exposed dashboards

How easy is it to install in a vehicle or boat?

Installation is straightforward and flexible: you can drill a 30mm hole for a flush-mount or attach the panel with screws if matching holes already exist. The compact footprint and standard wiring make it suitable for factory-style retrofits or custom panels.

• Flush mount: drill 30mm hole and secure with included nut
• Panel mount: fasten the faceplate with screws—no extra drilling if holes align
• Simple two-wire hookup with clear polarity markings
• Compact size fits crowded dashboards and control panels

Which vehicles and systems can it monitor?

Compatible with most DC electrical systems, the Linkstyle voltmeter works in 12V and 24V environments, making it useful for cars, motorcycles, ATVs, RVs, boats and light commercial vehicles. It provides continuous feedback so you can spot low-voltage conditions or charging issues early.

• 12V systems: cars, motorcycles, SUVs, ATVs, UTVs, golf carts
• 24V systems: trucks, tractors, industrial equipment
• Marine use: boats and small craft with exposed dash areas
• RV and camper panels for battery monitoring while off-grid

Who is this for? The Linkstyle 2PCS Battery Voltage Gauge suits DIY enthusiasts, fleet operators, and recreational vehicle owners who want an accurate, low-profile battery monitoring solution. If you need a durable, waterproof meter that’s easy to fit into existing panels and provides both numeric voltage and a percentage readout, this compact LED voltmeter gives quick, actionable information without complicated setup.
