SUPNOVA Battery Monitor 7–100V IPX7 Waterproof with Bracket, Temp Display & Buzzer Alarm

SUPNOVA's IPX7 battery monitor is a waterproof digital meter that tracks 7–100V battery voltage, shows temperature, and sounds configurable buzzer alarms, all in a compact bracketed unit.

This lightweight meter is built to give fast, clear readings of battery voltage and remaining capacity for a wide range of systems — from motorcycles and golf carts to marine and RV batteries. It accepts multiple battery chemistries (including lead‑acid, AGM, LiFePO4 and ternary lithium), stores settings after power loss, and is housed in an IPX7-rated, splash‑proof enclosure suitable for outdoor use.

How will this monitor help me keep an eye on my vehicle or boat battery?

The SUPNOVA monitor provides real-time voltage and percentage estimates so you can detect low or high voltage conditions before they affect performance. It also logs the last configuration so you don’t have to reprogram thresholds after a power cycle.

• Measures 7–100 volts, covering 12V, 24V, 36V, 48V, 60V, 72V, 84V systems
• Displays voltage, capacity percentage and temperature in Celsius
• Sets audible low/high voltage alarms to warn promptly
• Power‑off memory retains user settings

What protections and durability features does it offer for outdoor use?

The case is fully enclosed and rated IPX7, which means it resists water exposure and dust ingress so it can be mounted on exposed vehicles, marine consoles, or in garages. It also includes reverse‑connection protection to avoid damage from incorrect wiring.

• IPX7 waterproof housing — survives immersion scenarios common for outdoor gear
• Dustproof sealed enclosure for reliable long‑term performance
• Input reverse‑connection protection reduces installation risk
• Sturdy bracket, adhesive pad and screws included for secure mounting

How easy is installation and operation for DIYers?

Installation is straightforward: red wire to battery positive and black wire to negative, with 60 cm (23.6 in) lead lengths for flexible placement. The display has simple button controls to toggle modes, configure alarm thresholds and view temperature, but an initial setup step is required to calibrate the percentage readout.

• Wires: red = positive, black = negative; 60 cm lead length
• Includes mounting bracket, double‑sided adhesive and screws
• Short press the "M" key to switch between voltage and Celsius temperature
• Follow the quick‑start setup to avoid a default 100% percentage reading

Who is this monitor designed for?

This SUPNOVA unit is aimed at owners and maintainers of small electric vehicles, motorcycles, boats, RVs, golf carts and off‑grid setups who need an accurate, weather‑resistant way to monitor battery health and temperature. It's also a good choice for workshops and fleet operators who want a compact, durable display with audible alerts and multi‑chemistry compatibility.
