Fly electrics for long and you’ll want to know watts, volts, and amps used. These indicators can tell you all you need to know about your aircraft’s power system. WattAge’s DCM (Direct Current Meter) gives you this information in an easy-to-use, in-line style meter. You can: fine tune your propeller or gear ratio; ensure you are not exceeding your system’s rated maximum current load; check that the motor is not drawing excessive amps; check the power output and compare different batteries; double check the output of your charger—do all this and more with the DCM!! Knowledge is power, and the more you know about your system, the better you can use it to maximize power and efficiency.
