True, and is technically better, but a bit overkill for a simple cheap voltmeter.
Mine off the sidelights is about 0.3 volts difference to the actual battery, which is fine to indicate issues and I know the offset either way. I can live with that error and save the hassle of wiring in a relay.
Ideal if you have a live off a relay already plumbed in though.
