    This Watt Meter measures current, voltage, peak current (Amps), peak power (Watts), minimum voltage (Volts), power (Watts), energy (Watt-hours), charge (Amp-hours) and temperature values for you, in real-time, for the circuit in which you connect it. Now you can stop wondering what's going on with your electric model and get answers that allow you to apply science to your hobby. The precise measurements you collect will help you fine tune your model to get all the performance that you want.

    Features
    Measures energy (Wh), charge (Ah), power (W), current (A) and voltage (V)
    Measures peak Amps, peak Watts ,voltage minimum (sag), peak temperature.
    Measures temperature in both Celsius & Fahrenheit (optional temperature probe is necessary)
    Auxiliary battery to power watt meter for measurement down to 0V
    Accurate & precise – 0.01 A current and 0.01V voltage resolutions
    Rugged – handles 50 A continuous and 100 A peak at 60V
    Small & light with a tough plastic case
    Precision Alu-Chrom current sensing resistor, with only 0.001 Ohms resistance
    Factory calibration stores constants in EEPROM to compensate for component tolerances

    With this watt meter, it is now easy to determine things like:
    Current through an ESC and motor
    The temperature & peak temperatures of an ESC and motor
    Estimate battery's running time for car or airplane
    ESC, BEC and motor efficiencies
    Charge put into and discharge from a battery
    Presence of peak currents that can damage components
    Presence of voltage sags that cause components to operate out of specification
    Why power is lost during acrobatics or extreme conditions
    Effect of gearing and propeller size and shape on power consumption and battery currents

    Dimensions: 2 x 1.75 x 0.5 in.
    Weight: 1.5 oz
