  1. The only way a shunt based monitor works is if all the negatives return through it. I have 3 x 12 volt battery banks. Each negative goes to the shunt. The shunt then goes to a bus bar. The bus bar has a connection to the chassis and the negative from all other devices. All the power from the whole battery bank returns through the shunt to the bank negative.

    Here is a link to how the Balmar SG200 monitor works. https://marinehowto.com/balmar-sg200-self-learning-battery-monitor/

  2. Any meter that indicates amperes. They measure the voltage drop across the shunt and the scale is shown as amperes. Could be a common dash meter showing charge discharge or a complicated battery monitoring device such as Victron. The small meters have the shunt inside the case. Battery Monitors measure higher amps and have a external shunt. Shunt is a resistor placed on the negative battery cable.  https://marinehowto.com/installing-a-battery-monitor/

  3. It isn't just Windows Support. It is security updates that stop. That will get you. My ThinkPad was supposed to be updatable to windows 10. When I tried through Lenovo, the update would not load. I spent a day dicking around with them. Then decided Lenovo isn't worth the trouble. Bought a new HP on black friday sale. 

  4. The wires would carry different amounts of the current. You could have many more amperes in one of the 10awg than it could safely carry. Overheating to the point it melts insulation and takes out some of the other wires. Other bad things could happen. You can buy 60 feet of marine grade 2awg for less than $175. Your charging system would work a lot better.
