BIR200 200-Amp High Current Dual Battery Isolator and Relay for Car Audio Systems (Handles up to 300-Amp Surge)

thank you so much super sevice and fast

The relay extremely quiet and at the same time is very robust in the power handling department. I would have given 5 stars but the post office lost the package for awhile and so my delivery was very much delayed. I am hoping the relay has a long lifespan as it will see near continuous duty.
