IPX7 Waterproof Battery Monitor 7-100V Tester with Bracket

This compact, rugged gauge is built for bikes, scooters, marine craft, RVs, golf carts and other vehicles that use 7–100V battery packs. Engineered for outdoor use with an IPX7-rated sealed housing, it resists dust and temporary immersion in water. The monitor supports multiple chemistries and voltages, stores your settings after power loss, and includes an adjustable buzzer for high/low voltage warnings and a temperature readout.

How does this monitor measure and display battery condition?

The device continuously reads battery voltage and converts it into a readable percentage state-of-charge by using configurable settings for different battery types. You can toggle between voltage and temperature displays, and the unit remembers your preferences when power is removed.

• Voltage range: 7–100V compatible with common nominal systems (12V, 24V, 36V, 48V, etc.).
• Default configuration for 12V lead-acid; user-selectable battery chemistry for accurate percent readings.
• Temperature shown in Celsius with a single key press for quick checks.
• Power-off memory retains alarm and display settings after shutdown.

What safety and durability features protect the monitor outdoors?

The enclosure is fully sealed and rated IPX7, so it stands up to rain, spray and short-term immersion. It also includes reverse-polarity protection to prevent damage if the leads are connected incorrectly, and a buzzer that warns you before voltage reaches critical levels.

• IPX7 waterproof housing for outdoor and marine exposure.
• Dust-resistant sealed construction for longevity in harsh conditions.
• Input reverse connection protection to safeguard electronics from miswiring.
• Adjustable audible alarm for preset low and high voltage thresholds.

How is the SUPNOVA monitor installed and set up?

Installation is straightforward: connect the red wire to battery positive and the black to negative. The package includes a mounting bracket, screws and double-sided adhesive so you can screw-mount or stick the unit where it is most visible.

• Wires are approximately 23.6 inches (60 cm) long for flexible placement.
• Mounting bracket plus adhesive and screws for surface or panel mounting.
• Simple initial configuration is required to match battery chemistry—follow the quick-start steps to avoid an incorrect 100% reading.
• One-button display switch ("M" key) toggles readouts and alarms.

What alarms and readouts can I rely on during operation?

The monitor lets you set both low- and high-voltage buzzer triggers to alert you before batteries become critically discharged or overvoltage occurs. Short-pressing the mode key swaps the display between voltage percent and temperature so you can monitor both at a glance.

• Low/high voltage buzzer with user-configurable thresholds.
• Short press toggles between voltage percent and Celsius temperature readouts.
• Audible alerts help prevent deep discharge or damage from overvoltage events.
• Settings persist after power cycles for consistent protection.

Who this is for: technicians, DIY vehicle owners, marine and RV enthusiasts, and fleet managers who need a compact, weatherproof gauge to monitor multi-voltage battery systems. If you operate electric motorcycles, golf carts, boats, or any equipment using 12–84V battery chemistries (including lead-acid, AGM, LiFePO4 and ternary lithium packs) and want quick visual and audible status feedback, the SUPNOVA IPX7 monitor is designed to give reliable on-vehicle readings and alarms without complex installation.
