Ok, so another question. I see that most of us have issues with too much of a current draw. I am running an independant circuit in my Explorer that has a 40amp relay and a 30amp fuse. I don't want to pull more than 20 amps on the system, but when we have a run away or not knowing what our electrolyte limits are, we run into trial and error mode and sometimes, like me, have a melt down. Is there something that can be integrated into the circuit that can limit the current to a desired peak?
