Excellent, but I have a question, which is how do I charge by this circuit with 2 (18650 ) batteries respectively, with a total charging value of 8.4 volts, thank you
Can we charge 12v batt using that circuit?i am thinking to use 14v to 20v source and adjust the preset to 13v or 12v output..is it possible?well,i tried that circuit in my 3.7v batt,and i was using 0.1 ohm resistor for high current..i put 2 pcs 103 2kv cap to protect bc457 and preset from burning..
