Well, HOWDY Paul... <again..

>. Happy to see you finally posted!!

Some of us got a bit spoiled with our manual chargers over the years...
My chargers (same model 'twins') run at 20 amps. ( I purchased this model purposefully..

)
10-13 years ago there were many more 'choices'..

I am more concerned with the 'light' weight cables/clamps on some of the new fangled power supplies, as Electrolysis demands are substantial...
