Yeah, Land, I think all your conclusions and understandings are right on. Bottom line, unless a user is willing to parallel a couple or few of them together, they take too much babysitting and the higher current takes them out of any expected durability. This is using them as a full-charger, of course. If using as an equalizer, will they stand up to the higher voltage if the current is limited? And, if so, how delicate does a user need to be since we may bring a Cheapowatt into service when a battery is able to accept quite a bit of draw?
Everyones needs are different and these power supplies aren't a good fit for everyone is what I'm thinking. If a user needs full charge capability up to and over 40 amps, there may be a better solution. The trick is to find something capable of the higher current, adjustable output, and at a decent price.
