Frequently Asked Questions

Q: What battery types are compatible with the Gaqqee DC 4–55V Programmable Voltmeter?

A: The voltmeter supports three major battery chemistries: NCM (Ternary Lithium) in 2–12S configurations, LFP (Lithium Iron Phosphate) in 2–14S configurations, and Lead-Acid (LAB) batteries in 2–4S configurations. This makes it highly versatile for electric vehicles, power tools, energy storage devices, and DIY battery projects.

Q: Do I need to solder wires to install this voltmeter?

A: Yes. The meter uses a positive terminal solder pad connection method, which means users are required to solder their own wires for installation. Basic soldering skills and equipment are needed. The meter dimensions are 58.35 × 17.7 × 5 mm with a mounting hole spacing of 48.78 mm for easy panel integration.

Q: What does the low-charge alert look like on the Gaqqee Voltmeter?

A: When the battery charge level drops below 5%, the display will flash a visual alert, giving you a clear, immediate warning that your battery needs attention. You can also configure adjustable standby time settings to help manage power consumption, as the operating current is under 10mA.

Q: Is this voltmeter certified for safety and environmental compliance?

A: Yes. The Gaqqee DC 4–55V Programmable Voltmeter and Battery Level Indicator is CE and RoHS certified, meeting international standards for electrical safety and restriction of hazardous substances.
