Default Watt's Up Wattmeter in Excellent Condition (GREEN)

This is a sale for a "Watt's Up" RC battery Watt meter from RC Electronics in excellent condition that measures and calculates all the electrical parameters you need to get high performance from your R/C planes and/or cars. It is an essential tool for increasing the performance and safety of your electric-powered R/C model(s). Leaving connectors attached. No connectors are included when new.

* Predict model airplane flight time or surface run time
* Ensure peak currents are safe for motor, wiring and connectors
* Check battery health and whether battery should be retired
* Evaluate R/C battery charging efficiency
* Verify that the minimum voltage while operating is within specifications
* Choose the best propeller or gearing and the most efficient motor
* Check for wiring and connector power losses
* Measure power and energy consumption of ANY device with a battery

Key Features:
  • 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
  • Complete User Manual Included
Specifications:
  • Voltage 0-60 V, resolution 0.01 V. That's a 14 cell series li-poly pack!
  • Current 0-100 A peak, 50 A continuous, resolution 0.01 A
  • Charge 0-65 Ah, resolution 0.001 Ah. That's ~32 Amps for two hours!
  • Power 0-6500 W, resolution 0.1 W. That's ~8.7 Horsepower!
  • Energy 0-6500 Wh, resolution 0.1 Wh. That's lifting a 50 pound model into outer
    space (65 mi.)!
  • Operates from 4.0-60 V, 0 V with optional receiver battery pack
    16 x 2 STN LCD display
  • Powerful, 8 MIPS micro-controller
$60 price tag if bought new.

Asking $39 shipped
