SUPNOVA Battery Monitor 7-100V – Digital Display, Buzzer Alarm, Temperature Readout

Keep battery health in view with the SUPNOVA Battery Monitor. The compact device translates complex battery data into a clear digital readout, helping you stay aware of voltage, remaining capacity, and temperature across a range of systems. Designed for indoor use, it pairs a wide voltage window with simple wiring and practical alerts, so you can plan maintenance and charging more confidently.

Wide compatibility and sensing

The monitor supports a broad 7-100V input, covering common setups from 12V cars to higher-voltage golf carts and marine systems. It works with lead-acid, AGM, LiFePO4, and ternary lithium batteries, and it displays the remaining capacity as a percentage to help you gauge when a top-up is due.

• Voltage range: 7-100V, with presets for 12V, 24V, 36V, 48V, 60V, 72V, and 84V.
• Battery types: lead-acid, AGM, LiFePO4, and ternary lithium chemistries are supported.

Smart features for real-world use

Key functions include a low and high voltage buzzer alarm and a temperature readout in Celsius. You can toggle the displayed voltage and temperature using the M button, so you see what matters most in the moment. The device also uses power-off memory to retain settings between uses.

• Low/high voltage alerts help you respond before a drain becomes problematic.
• Temperature readout supports on-the-spot monitoring of charging conditions.
• Power-off memory keeps your preferences intact after power loss.

Easy setup and safe operation

Connect with the color-coded wires: red for positive and black for negative. The leads are about 39.37 inches long, giving you flexible mounting options. The unit is CE-certified and designed to stay cool during extended use, though it is intended for indoor environments and is not waterproof.

• Simple installation with clear color coding: red = +, black = −.
• CE certified for reliability; no overheating under normal use (≤100V).

Note: After unboxing, perform the basic setup per the instructions, or readings may default to 100%. This monitor is ideal for bikes, golf carts, cars, boats, marine craft, and more, acting as a practical companion for routine power checks and planning.
