I am trying to build a smart car.
I have 4 DC motors with tires. They are yellow 3-6V hobby project motors. I have two L298 H-Bridge boards and 1 relay.
I connected two of motors to one H-Bridge and other two to the other H-Bridge. I want to control it with my Raspberry but the power sources should be different because of the motors' current so I am using 12V battery for the motors. I also want to use one relay to control its power with the Raspberry to switch. My relay is FL-3FF-S-Z 5VDC single relay (10A-250VAC/30VDC, 12A-125VAC/28VDC.)
Can my relay support the current for 4 DC motors?
10A is written on my relay however I dont know if it can reach to 10A with my 12V battery.
When my motors are loaded, how can I calculate the maximum current if it is working with my relays threshold?
