Hey guys me again LOL,
I just came across this interesting solderless 18650 parallel battery pack solution that comes with balancing unit which seems like to me is just a couple of mosfets, big Power resistor, and some type of IC. I think it is a comparator Maybe. Basically it just senses the battery voltage and if it gets above 4.2 volts is switches on the mosfet to drain power through the resistor. Straightforward enough. I would like to build a bunch of my own and I was hoping somebody could look at the picture and determine exactly what it is and maybe the circuit itself. I know there's also an LED that lights up when the mosfet is putting power through the resistor but next to the IC there is this round component that I'm not exactly sure what it is. the picture below
Thanks again for all your guys's help I really appreciate it!!!
