I have letz say 14ah of 48v sla, and I want to use one single small form factor PC power supply to charge. How do I go about doing this? First I would have to connect the green wire and the black wire together. Then branch the 12v rail to 4 plugs and connect them in series, then add the 5V rail and 3.3V rail to produce 56.3v. How do I limit the current? This is a 300w power supply.
