(HPVM) High Precision Voltmeter
Description
HPVM Voltage Meter
- Precision volt meter for automotive and car audio
- 1.3-inch LCD with 65,000 colors
- Monitors two sources at once
- Measures up to 18 volts
- Customizable display with ten gauge faces
- Bluetooth-enabled connection with free AuralSync app
Your Style. Our Precision.
The HPVM is the most versatile graphing volt meter available today. Accurate to 1/500 of a volt and capable of measuring two sources simultaneously, the HPVM comes equipped with Bluetooth connectivity, allowing it to connect to the free Aural Sync™ app, optional AuralSync Companion Smartwatch, and other AuralSync-enabled devices.
Use the app to choose any one of ten gauge designs, then create user-definable voltage ranges and custom colors to make each look match your needs, and your style.
Overbuilt To Last
Extremes in vibration, humidity, and temperatures are always attacking everything in your vehicle. A solid aluminum case houses high-density/temperature internal supports, and gold-plated ENIG PCB to survive – and thrive – in any build.
Maximum Battery Efficiency
To save your battery power, the HPVM is equipped with Deep Sleep mode. When a gradual voltage drop with no transients is detected, the meter automatically reduces power consumption to just 167 milliwatts. At that rate, it would take 7,059 hours (294 days) to fully drain a 100 amp hour 12V AGM battery.
Once the meter detects a voltage spike, it instantly returns to full operation. It will also display total battery drain during low-power mode and issue a bright red warning if the voltage drop was significant, signaling a weak battery or excessive parasitic draw.

So first time buying from LF Audio loving the build quality setup was a tad bit confusing at first the pin number for each unique unit should be placed on the back like the first gens just IMO but overall pretty much self explanatory I do love the app connection and the customizations would be nice to start up with a custom logo and the lf audio logo as well but over all I knew I was going to like this unit so I had to buy 2 1 to place on my AE Kilo110 v1 and one to place upfront on my dash overall 5 stars just the pin for the unit was a bit confusing
Awesome unit!! Well built and very customizable. This is my second product from LF Audio. I also own the WVC Lite 6CH and I'm extremely impressed. As soon as the Powermeter is available I'll be purchasing it too!!
Quality built, fast readings,accurate, easy to install, and program. Badass options to customize the display.
I replaced my Usain Volt meter with it.Fast response time to display voltage. Awesome options. Durabile af. Looks badass wherever it's mounted.
Works exactly as advertised. Multiple gauge faces with 4 position viewing and decimal adjustability is great. I'm running 1 decimal place on a single signal. Works great. Matches my dmm exactly. Good work. Con would be it's a little small, but it's really not because the screen is clear and bright enough.
