Review on High or Low Side Voltage, Current, Power Sensor - Adafruit INA260 4226 by Sean Patel

You MUST solder and be familiar with R Pi or Arduino but these guys are SUPER nice to use. I installed 5 on a prototype board and now have control over all the different parts of my development robot so I finally understand what is consuming battery life. It took a few hours to figure out and put together, but the code is simple (thanks Adafruit!) and will be very useful when complete. I buy more to connect to other devices and connect the whole lab to MQTT messaging so I can control everything from one computer. NOTE: Must share ground with INA260. If you overload the current, they immediately self-destruct.
