    I connected a 5v relay to raspberry-pi 3b+, 12v peristaltic pump and 12v Li-ion battery. And the pump works but my question is can the 5v relay handle this or should I get a 12v relay.

    nice project. will like to try it. can we use the relay as a regular switch. i mean here you are using it with 12 volts DC power supply and motor, what if i want to use it with a regular light bulb and mains power supply. will it support or blow up.
