So I've been working on my cell balancer design and there's always been a strange problem with it where RL is acting like some kind of weird hysteresis. LED 2 is used to indicate whether the mosfet is conducting or not. If I disconnect the load resistor and adjust the trimmer until the LED comes on and then connect the load resistor, the LED goes off and doesn't come back on unless I increase the supply voltage or adjust the trimmer. K1 4 and B+ are all connected together and are at the same voltage. I replaced the hysteresis resistor with a capacitor and this prevents the comparator switching at very high frequency causing the mosfet to overheat. It now switches at around 20hz
So I did some tests by only adjusting the supply voltage measured at B+ / K1 4.
With RL disconnected, the LED starts flickering at 3.878v and is fully on at 3.882v
With RL connected, the LED wouldn't start flickering until the supply voltage went to 3.974v
I don't understand how the presence of this load resistor on the mosfet is affecting the voltage at which the comparators are triggering because it's not directly connected to their inputs. I even measured the inputs and the resistor isn't affecting their voltage. The whole thing is set up on a breadboard currently
