Power Analyzer Watt Meter 130A

There is no better or easier way for you to measure your power system than by using a watt meter. This handy little device takes the guess work out of it by reliably and accurately measuring watts amps and volts. 
If a watt meter saves you just one motor or ESC then its paid for itself. We've all seen someone burn a motor or ESC at the track/field with a new prop or pinon. You can avoid the disappointment of a failed power system by ensuring your setup is within the limits of the componentry   

Advantages:
Ensure peak currents are within tolerance for your power system
