"Watt's Up" Battery Meter and Power  Analyzer (Version 2)

Tells you about your electric bike and scooter operation and can be the most valued of your electric bike or scooter accessories.

Use the Ah and Wh measurements as a "fuel gage" for range so you don't get stranded. They're much more accurate for this than voltage measurements or LED "Battery Indicators".

Measure charge consumption (Ah & Wh), motor Amps, battery voltage and efficiency, power usage and troubleshoot hard to find electrical problems with the peak Amps & Watts and minimum voltage measurements. The peak and minimum measurements also help you verify safe operation of motors, controllers and batteries.

Helps you evaluate the effect of component changes and tuning.

"Watt's Up" works with any battery or motor type.

"Watt's Up"does it all. You'll wonder how you got along without it.

Features:

• Captures peak Amps, peak Watts, and minimum Voltage
• Charge: 0 - 65 Ah, resolution 0.001 Ah
• Energy: 0 - 6500 Wh, resolution 0.1 Wh
• Voltage: 4 - 60 V, resolution 0.01 V*
• Current: 0 - 100 A Peak
• Power: 0 - 6500 W, resolution 0.1 W
• Low, 0.001 Ohm insertion resistance
• Small size and lightweight - 2.8" L x 1.7" W x 0.83" D, 2.5 oz.
• Full manual with electrical tutorial
• Made in USA to ISO 9000 standards
• One Year Warranty

  * When using auxiliary power/battery input the minimum  is  0 V.

Better than a multimeter because of higher current limit, real time calculation of Power, Ah and Wh measurements, capture of peak Amps, peak Watts and voltage minimums and much lower shunt resistance.

Easy To Use
"Watt's Up" is easy to use. Connect it like jumper cables between battery and motor controller. Plus to plus, minus to minus. Supplied without connectors so you can connect it however you like.
