Re: Voltage tester idea
"Could you not deliberately oversize the wires from your bank to your voltmeter? "
Voltmeters always draw SO little power in the sense leads, that you'd really have to try hard to find a wire guage small enough to have any voltage loss on that run.
Even one of the "self powered" two-lead LED types, what is the total consumption? Maybe 100mA?
