Minnesota I bought the Turnigy meter as you suggested hooked it up and of course there was no wind the day I did it. But here is my question, I did leave it hooked up when I left the camp, and went back 4 days later it was still on but my batteries were down to 11.6 volts. I realize now that this meter is just to check the info then disconnect it. Any Idea how much 12 volt power this takes when left on. It appears to me it may be a little power hungry, I am hoping so or my batteries ar getting quite weak. http://hobbyking.com/hobbyking/store/uh ... duct=10080
Well to bring more to the subject of batteries. I am finding out when I do not get any wind for a few days........ No matter the voltage in the battery. It always ends up back at 12v in less than 2 days. Being flooded lead they clam about 2-10 percent in a month. And this is with nothing hooked up not even a charge controller. That is why I have been playing with grid tie now.
