eTopxizu (cheapowatt) 30 amp power supply Guinea Pig

Correct on all accounts as far as I know. Those spec sheets seem to be written in Chingrish, I would be interested in actual overload functionality. Not sure how overvoltage protection would come into use, unless the voltage pot is reduced below battery voltage.

When I did that on my cheapowatt, it whined in a high pitched note in protest and I would disconnect it from the battery, let battery voltage drop, then plug the cheapowatt back in and then dial it to float voltage.
