Our Watts Up DC Ammeter measures eight parameters: Amp hours (Ah), Watt hours (Wh), voltage, Watts and captures peak current (Amps), peak power (Watts) and voltage sag (minimum Volts).

Description
Why You Need One
Without a wattmeter, a hobbyist is left to guess or estimate what's going on. This trial and error approach can rob performance and damage components, or worse. Pros know that you can't get top performance from RC cars & planes without the accurate information a wattmeter provides. The "Watt's Up" is easy to use. It's like jumper cables. Connect between a power source and a load and you can measure all the important electrical parameters. It doesn't interfere with the components you connect it to.
