Hello.
First of all I wanted to thank you for posting useful information.
I have no experience in such modifications, but I would like to include voltage regulation in this power supply in the range of approximately 10-12 to 14V to reduce the current at the beginning of charging when connecting a discharged battery.
If I understand correctly, you need to increase the OVP by adding 16kOhm (OVP = 14.5V), and possibly a resistor for the UVP.
However, what potentiometer should be used (new mounted on the housing) to regulate the voltage and what additional resistor should be used for it?
