Excellent video! How long do those batteries stay good for? I just bought this system and im less than a month away from the fourth and I'm ready to program. Also if the batteries are removed for storage do the modules need to be reprogrammed?

How many volts is it? And are you saying it can have up to 100 areas? So you buy more of the receivers and label them up to 100?

I got mine from China $100 that's it and it works fine. I am your 2nd sub. 117
