Hello, I wanted to present one more project using an ATX power supply and in my case AT. I made him a battery charger. Li-ion up to and including 5S. I looked at Interk a little and did not find anything similar, so I think it is my project, so to speak. I used it to automatically turn on the fan so that it does not make unnecessary noise, and the module to detect a charged battery pack and of course the balancer http://www.zajic.cz/omezovac/omezovac.htm. To power the fan control module and the charging module I used a LED bulb power supply giving 22V, lowered it to 12V. The rotary switch controls the power supply voltage by selecting the RX resistor and including it in the appropriate balancer sections. I also used a second error amplifier in the TL494 circuit to regulate the charging current, and after charging the charge module connects 4.7k in parallel to R1 4.7 resistors reducing the current to a very small value. The project is practically checked.
