I have seen people complaining that these cheap ones are not accurate, and I need to know it will be accurate and durable. The reason is I now have a deep cycle battery, will be plugging it in at night, shutting off the alt for 12-24 miles of driving. I will run the battery low, and I will need to know when to switch the alt back on. But I don't doubt yours may be great... can I have it?
