  • Battery Voltage Meter

    Does anyone know a good cheap Battery voltage meter i can put inside my vehicle to tell me the current Power left in my battery?

    All the one's i have found are in China... and I really dont want to wait like a month to get it...

    Power? Nope. Voltage? Sure, go to any advance auto parts or autozone, they have voltmeter gauges you can purchase to put in your car.

    Or much better, use a fusion brain, and display the voltage on your carpc

        No such thing.

        But I have a Honk Kong 3-digit voltmeter in my dash which tells me the battery voltage.

        That does not indicate the power remaining in my battery unless:
        - the battery voltage is in the rested state (ie, typically 12-24 hours after a charge, else surface charge has been removed);
        - I assume its voltage (between say 11.4V & 12.6V) is proportional to its full capacity - whatever that capacity may be at that age & temperature.
