Watch out

  • 1733 is the yellow display and 1733200 the blue display of the same voltmeter; check the part number when ordering.

Why people pick it

  • Shows battery bank voltage at a glance, permanently mounted, on 12V or 24V DC systems from 8 to 36V per the spec sheet
  • Bright yellow OLED reads in daylight and is rated IP66 on the meter face, protected against powerful water jets, per the maker
  • Yellow OLED lifecycle is 100,000 hours, per the Mini OLED sales sheet
  • Reverse-polarity protected, so crossed wires during install don't kill it, per the maker
  • Fits a common 1-1/8 in (29 mm) panel hole, the same cutout as standard car and boat accessories, per the dimensioned drawing

Know before you buy

  • Voltage only: it does not show current, watts or charge state, unlike a watt meter or battery monitor
  • Needs a hole cut in a panel and two quick-connect wires, so it's a permanent install rather than a quick check tool
  • Panel mount only: it can't be used as a handheld probe on unmounted batteries or loose wires
