Re: Please critique my charging schematic

Well, yes, but we expect a breaker to be a breaker. These look like the common lighted 12-volt switches made, sold, used, by many sources. There's no way (from the picture) to tell that these are breakers, instead of the common lighted switches, is there?
An echocharger isolates the batteries while consuming very little power. A diode isolator consumes about 1/2 volt all the time, so you are wasting power. They're cheap but they're inefficient.
And yes, paralleling one good battery with one bad one will pull down the good one until they equalize. Not necessarily dangerous but a good way to kill your good battery.
