Agreed, but the voltage drop is 30 mV which is so low it's ridiculous so it doesn't require voltage sense wires to compensate for a voltage drop. That's how the crappy isolators works...they have a HIGH voltage drop and do nothing to compensate, or place sense wires on the battery to compensate for the HIGH voltage drop. On this thing, because the voltage drop is hardly perceptible, no need for compensation. I did my homework on this one.

Hi,
Unless the perfect switch has battery voltage sense wires, there will be voltage drop across it.
I prefer a (good quality) relay myself.
