I'm pretty new to stack exchange and I've only just gotten my basic circuit analysis classes done in college. For my school's solar racing team, I've been tasked with designing a constant current load circuit to discharge modules of the battery pack at 20 amps. I've done my research, but am still pretty lost as to what parts to use to design this circuit, and then convert it to a PCB. There are 35 modules, 12 batteries per module, and have voltage of 3.6 volts. The capacity is 36 Ah. Can anyone help me out with designing a constant current load that will discharge the modules at 15-20 amps?
Thanks a bunch, Alvin
