I am looking for a device or small circuit to detect my car battay voltage level and overload protecting device.
This is what I want to make or find:
When I run few devices from my car battaery, I want to cut off switch before my battery drains . If my battary is drain to the low I cannt start my car, I want some device to detect battaery thresh hold level.
Much appreciate your help for this.
Any web side, products or design idea welcome.
