Review on 💡 Watt Meter Power Analyzer HCDIM 150A: High-Precision RC Power Measurement with Digital LCD Screen by Carl Higdem

I didn't read anywhere in the description that the operating voltage range is 8-60, but it says so on the box and the gauge goes out about there. If you're running a larger than usual battery and don't mind not seeing numbers below 8vdc, it will run on 2 second lipos. At 2s you don't have much headroom to test before the battery voltage drops below the operating range. I'll keep it, but beware of this limitation.
