Fast Flite "Watts Up" Meter

The New "Watt's Up" RC battery Watt meter measures and calculates all the electrical parameters you need to get high performance from your RC Cars & Planes. It is essential for increasing the performance and safety of your electric Radio Controlled model. With the best balance of specifications and features on the market, you can stop guessing and start knowing "Watt's Up" with your model.

The "Watt's Up" RC battery Watt meter helps you:

Set speed control cutoff voltages and currents
Tune performance by comparing different setups of propeller, motor, gearing, speed control and battery
Measure a full battery charge and compare to spec when charger claims done
Check peak currents are safe for battery, speed control, motor, wiring and connectors
Predict airplane flight time based on ACTUAL conditions in your model
Check cell balance of individual cells in ANY chemistry battery packs Check battery capacity and health and whether battery should be retired
Verify that the minimum voltage under load is within specifications Check for wiring and connector power losses
Measure power and energy consumption of ANY device with a battery

Fine-tuning your electric RC cars & planes for great performance doesn't have to be a guessing game. Electric RC cars & airplanes can be analyzed to improve performance and duration in ways their gas powered brethren can not. Now, with the "Watt's Up" watt meter from RC Electronics, Inc., precise measurements of Volts, Amps, Watts, Ah and Wh enable any R/C car, truck, airplane modeler to optimize battery, motor and electrical performance in a methodical manner.

You can get the results you want and know how with much less hassle, time, and cost.

Key Features of "Watt's Up" power analyzer:
Measures energy (Wh), charge (Ah), power (W), current (A) and voltage (V)
Connector to use a receiver battery for measurement down to 0 V
Captures current peaks and voltage minimums(droops)
Accurate & precise - 0.01 A current and 0.01 V voltage resolutions
Rugged - handles 50 A continuous and 100 A peak at 60 V
14 ga., 7 x 37 stranded, high temp silicone rubber insulated wire without connectors
Small & Light: 2.8" long x 1.7" wide x 0.83" thick (70 mm x 44 mm x 21 mm), 2.5 oz.
Acts like a wire so doesn't affect model's performance. Precision current sensing resistor, with only 0.001 Ohm resistance and circuitry only draws 0.007 Amps
Uses DSP to increase ADC resolution and differential measurement amplifiers to increase noise immunity
Factory calibration stores constants in EEPROM to compensate for component tolerances
