I checked out your website, Mr. chemelec.
Really cool stuff you got there!
About your circuit diagram, ..........
1) RX is rated at 4K7, and according to the formula, RX= 06V / 0.120A, which should be 5 OHMs, right? Or am i a bit mixed up? The circuit i came accross first, turns out to be just about identicle to yours, only it has an led between the collector of the transistor, and the adjustable pin of the v-reg (goes off when fully charged / minimum current is reached)
. they use a 1 ohm resistor (in the same place as your diagram) for a 650mAh charge, which complies with you formula.
2) i want to use your circuit to charge higher current batteries, of between 25 and 45AH. im assuming i could get away with an LM338, on a large cool rib, but i doubt the transistor will survive. Can i use a TIP41C instead (15A Rated, as opposed to the 0.6A of the 2N4123) ? Other substitutes? ideas?
