Paralleling Power Supply Units Made Easy ???
I am considering paralleling a couple of 20a variable adjustable psu's for 40a charging. According to what I have read on the world wide inter-web, it can be done quite easily, provided the following ...

...So it's really no different than a so-called smart charger! Just re-branded, re-purposed, pre-set psu's...(Sneaky buggers).
And so I imagine, when Amps are pre-set, and locked in to cc mode (this unit has a lock feature, as well), and one applies it to an already full battery, it sorta "tricks" the psu into seeing the batt as 'thirsty', and holds amps steady while volts rise.
