Why do you need a wattmeter?

On a new installation it is critical! It helps you determine if you are stressing or damaging your electric motor or battery with the prop / load you have placed on it. Can your battery actually hold up to the demands you place? Are you on the verge of burning out your motor? Do you have a short in your motor? Out of balance battery? Is your cutoff on your speed controller working properly? To summarize you need it to verify and optimize motor performance while measuring, testing, and matching your components. Solve your problems before it's too late!
