SUPNOVA Smart Battery Monitor 7–100V for 12V–84V Packs — Buzzer Alarm & Temp Display, Weather-Resistant

Designed for vehicles and equipment that use a wide range of battery types, this SUPNOVA monitor provides continuous voltage and temperature readouts, configurable buzzer alarms, and power-off memory so your alarm thresholds and preferences are retained. It fits 12V, 24V, 36V, 48V, 60V, 72V, 84V battery systems (7–100V range) and works with lead-acid, AGM, LiFePO4 and ternary lithium packs. The unit is weather resistant for indoor or outdoor mounting and includes reverse-connection protection for safer installation.

How does the monitor display voltage and temperature?

The front panel alternates between voltage percentage and numeric voltage values; a short press of the "M" button toggles between voltage and Celsius temperature readouts. Readings are immediate and update in real time so you can watch the battery condition during charging, discharge or storage.

• Voltage range: 7–100V compatible with common pack voltages (12V–84V presets)
• Temperature shown in Celsius when toggled by the M button
• Numeric and percentage display modes (percentage requires initial setup)

What alarm and protection features are included?

The monitor can be configured with both low-voltage and high-voltage buzzer alarms to warn of out-of-range conditions. It also has input reverse-connection protection and a waterproof, dustproof housing for durability in outdoor environments.

• Configurable buzzer alarm for low and high voltage thresholds
• Reverse-connection protection prevents damage from miswiring
• Weather-resistant surface suitable for indoor and outdoor use

How do I install the SUPNOVA battery monitor?

Installation is straightforward: connect the red wire to battery positive and the black wire to battery negative. Wires are 59 inches long with a 3.5 mm diameter to reach common battery locations; follow the quick setup instructions so percentage mode calibrates correctly.

• Red = positive, Black = negative; 59-inch wire length for flexible placement
• Wire diameter: 0.138 inches (3.5 mm) for reliable connection
• Initial setup required to prevent default 100% percentage reading

Will it remember my settings if power is lost?

Yes — the device includes a power-off memory function that stores alarm thresholds and display mode so your configuration returns after power is restored. This avoids reconfiguration after battery swaps or temporary disconnections.

• Nonvolatile memory keeps alarm and display settings after power loss
• Simple key controls let you change thresholds quickly
• Ideal for vehicles, marine, RV and stationary battery systems

Who this is for: The SUPNOVA Smart Battery Monitor is made for owners and technicians who need an accurate, weather-resistant gauge for multivoltage battery systems — including motorcycles, electric scooters, golf carts, cars, boats, RVs and marine equipment. It suits DIY installers and fleet maintainers who want audible alerts, temperature readout and retained settings for reliable field use.
