You know I remember looking through the manual thinking there has to be a way to shut this thing off. I was probably in my typical big rush and just didn't see it. Good to know for other people, I suppose I could always solder it back on if I miss it. I think it is a great little charger for the price and all the features it has. If my hack fails it will probably be time for a new charger. See what Hitec is making then.
