Compact Voltage Tester for 6V–48V Systems

This SUNAPEX digital voltmeter measures DC voltage from 5V to 60V, covering 6V, 12V, 24V and 48V batteries found in motorcycles, cars, RVs, golf carts, marine craft and off-grid solar banks. The unit weighs 1.28 ounces and measures 3.15 L x 1.56 W x 2.36 H inches, so it fits in a glove box or tool bag. It works with LiFePO4, AGM, GEL, flooded lead-acid and deep-cycle chemistries.

Clip-On Operation With Instant Readout

Connect the insulated red clip to the positive terminal and the black clip to the negative terminal; the four-character LCD displays the voltage in about two seconds with no buttons or menus. The tester is battery-powered and reads DC voltage only — it cannot perform CCA, load or alternator tests. Because the clips are alligator style, ensure they grip clean metal to avoid a false low reading.

For Quick Health Checks, Not Deep Diagnostics

Suits owners who need a portable go/no-go indication of battery state of charge across multiple voltage platforms. Not for technicians who require conductance analysis, internal resistance data or charging-system waveform capture. Buyers needing AC measurement, data logging or Bluetooth connectivity should look at a different instrument class.

Questions about this item

How do I know the LCD display is working correctly after I clip it to the battery?

The 4-character LCD lights up within 2 seconds showing a DC voltage value between 5 and 60 volts. If the screen stays blank, check the clip polarity and battery charge.

What comes in the box and do I need anything else to start testing?

The tester with insulated alligator clips is the only item included. No separate battery or cable is required because the unit draws power from the circuit under test.

Which voltage range should I rely on for a 48 V golf-cart bank versus a 12 V car battery?

The single 5 V–60 V range covers both; the same clips read 12 V car and 48 V golf-cart systems without switching modes.
