Frequently Asked Questions
How is this battery monitor wired?
It uses a two-wire hookup with pre-soldered flying leads on the rear: red connects to positive DC voltage (VCC) and black connects to ground (GND).
Does the display remain lit continuously?
Pressing the front TEST button toggles the display active, allowing quick voltage checks without imposing continuous standby drain on small battery packs.
What mounting cutout is required for this meter?
The front face measures 46 mm across the display bezel, allowing installation into a rectangular cutout or direct adhesive mounting to a flat dash panel.
Can this monitor run from a 12V lead-acid battery directly without a separate power supply?
Yes. Because the meter operates across a 7V to 40V DC range, it powers itself directly from the battery terminals it is measuring without requiring a separate power tap.
A small meter on a battery box takes the guesswork out of whether you have enough juice to finish the job. Wire it up, hit the button, and know where you stand.
