I’m just curious what kind of protection you would typically expect to see on a battery powered circuit. Circuit in question is a simple 24v dc relay controlled motor. Main power source would be 2x car batteries in series or temporarily a back up lipo/li-ion pack. Motor rated current is 2A but I may also do another with a (24v dc) 5A motor.
I know an AC mains circuit would have breakers, fuses in addition to whatever protection is offered by the psu or motor driver itself but I know very little about portable or battery powered electronics.
The motor was expensive and I want to keep it, the batteries and myself safe. Would a simple linear voltage regulator provide ample voltage, over current and reverse polarity protection on the circuit side of things?
