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 ...

I see there's confusion regarding cc and cv. cc and cv are modes of power supply operation. Virtually all regulated ps's have a current limit. Without the current limit, the supply will go out of regulation and probably burn up at higher current levels.
When in cc mode, the supply voltage can vary from 0V to the supply voltage set point. The battery voltage will dictate what the supply voltage is:
V_ps = V_bat + I_cc * R_cable
When in cc, the supply voltage will always be a constant (I_cc * R_cable) above the V_bat.

These units are both. Please keep in mind I've never used one of these, and don't even know what puts them into either cc or cv to begin with (i guess I should premised this in my original post).
