Arduino Wattmeter project

I want to make a Arduino Wattmeter which also displays current and voltage, I watched this video: But I want to use it for calibrating my drone's power module, so I need that Wattmeter to take atleast 15-20A safety. Is it possible? And I am completely new to Arduino, just learning the basics. So sorry and thanks.
