HI guys
About the charge voltage for my batteries I have tested for 3 days in a very good wind, (sometimes more than 12 m/s) and when they are at rest the voltage don't go up than 12,56 volts,(about 90%) so for charge this batteries I need more voltage.
I try another source of information, I found the web page of then, send a mail explain this situation and their answer is that I should charge the batteries at 14, 4 volts, because there's a cycle of charging and discharging.
Well next few days when I get home again I`ll set the controller to 14, 4 volts and check it one more time.
