Greetings, I'm wanting to replace an automotive type cube relay (Omron G8JN-1C7T-R-DC12) in a circuit I built last year for the DC power distribution system in my home built camper with a power MOSFET circuit in order to save some power while in discharge mode. The relay is used in line with a 13.3v LiFePO4 battery and controlled with a small signal relay and an OrionJr BMS to send current to a fuse panel. Maximum current demand might be as much as 25-30 amps with everything running. The relay is constantly energized as long as the BMS allows discharge. With a 64 ohm coil, it amounts to a waste of power. A MOSFET seems to me to be a better solution. I've begun learning about these devices and circuits, but I get lost when I look at the specs sheets provided by suppliers. I trying to find a simplified circuit to help me make this change. Thanks for reading, Chipper
