Product Details
- Amazon Sales Rank: #6137 in Toys & Games
- Brand: Tenergy
- Model: WU100
Features
- Measures energy (Wh), charge (Ah), power (W), current (A) and voltage (V) for any rechargeable battery pack from 4 - 60V, including NiCd, NiMH , and SLA, and Li-Ion battery packs.
- Connector to use a receiver battery for measurement down to 0 V and captures current peaks and voltage minimums(droops).
- Accurate & precise - 0.01 A current and 0.01 V voltage resolutions.
- 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
Product Description
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 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.
Fine-tuning your electric RC cars & planes for great performance doesn't have to be a guessing game.
Measure power and energy consumption of ANY device with a rechargeable battery pack, such as:
Airsoft gun battery pack, Bike lighting battery pack, E-bike and Scooter battery pack.
Combine the power analyzer together with our 2.4V - 7.2V, 7.2V - 12V, 24V NiMH universal smart chargers , and with 3.6V - 14.8V Li-Ion battery charger It is perfect tool to monitor battery pack's performance.

This item is marketed primarily by and in support of RC enthusiasts (toy makers and users). It, however, is not a toy and could cause harm if misused. I purchased the Watt's Up meter to monitor large batteries powering telescopes, associated computers, heaters and lights. This is in an outdoor environment subject to cold and moisture. Follow the instructions and be prepared to be delighted. Perhaps one of the few items on the market which delivers exactly what it is designed to do. Because my application is at night, I wish it had a backlight, but that's not a major problem. My astronomy gear is expensive, portable and uses DC power. The Watt's Up allows me to see what my electronics are really doing in the field, compared to what the manufactors say they are suppose to do. That means early warning for batteries, heaters, internal components (computers, motors and chip sets) and in the environment they are used. The Watt's up is well made, weather resistant, and compact. During a session, it even records relavant data and continually updates itself. It won't pour your coffee, but it will watch your DC systems better than you could without it. A very, very good buy.

Watch Video Here: http://www.amazon.com/review/R2ST1EH9CW2M2B The Watt's Up meter is an Inline DC meter that measures 8 parameters. Amp houses (Ah), Watt Hours (Wh), Voltage (v), Watts (w), and captures peak current (AmpsPeak) Peak Power (WattsPeak), voltage Sag (VoltsMin), and power consumed with (AmpHours)Here are the Watts Up parameter, ranges and resolutionVoltage, 0-60v, 0.01vCurrent, 0-110Amps, 0.01APower, 0-6554 watts, 0.01WCharge, 0-65 Amp Hours, 0.001AhEnergy, 0-6552 WattHours, 0.1 WhMinimum voltage is about 4.0 volts for operation of the meter itself.I use this for testing all kinds of things, from RC gear, to Ham radio gear, to portable Solar systems. It does take some work to get it plugged into things. It comes with about 6" of bare wire on each end. I had to make adapters for the various typs of connections I plan to use. I start with Anderson Power Pole directly attached to the unit and then have adapters for several others.5 Stars, this is an accurate and very handy tool

I purchased this meter after learning about it on a few of the solar power forums on the net. I am using it to monitor a small home solar power system. So far I am very pleased. I especially like the fact that it will measure amps and watts over time, along with minimum voltage and peak currents. I would say it is indispensable for maintaining or tuning a small solar set up. I have only been using it for a few days but if it lasts I am very pleased. The 60 amp limit is a real plus.
