The 80 amp battery isolator allows you to isolate the new secondary AGM battery while the vehicle's ignition is off, preserving your stock battery for starting. This system is quite simple: Key ON - both batteries are connected to X3's power system, Key OFF- the starting battery is isolated from the X3's power system, only drawing power from the 55 amp battery. It's that simple, and it works great.
