The batteries are an integral part of such a charging system, and they hold the voltage to correct levels just by their nature until they are full and bubbling. Bubble too long, and you risk battery damage from low electrolyte level. When the batteries are full, you must divert incoming wind power to a heating element or such to keep load on the wind turbine generator, or else it will overspeed for lack of load.
You could hook up a wind turbine using a 120 volt Ametek DC generator to a 12v battery bank...and you would get a little bit of power at low RPMs in low windspeeds...but as the wind speed increased, your power output would not--the resistance is too high in the stator of the 120v DC motor; it's not made for this kind of application. Better to find an Ametek that's rated at 1.5 to 2 times the voltage of your battery bank. Not a perfect match because of the high-resistance nature of DC Pm motors, but pretty good. You can expect quite a bit less than rated voltage, at rated rpm, of a DC motor when used as a generator. You can get lots of power out of them, but the RPMs must be significatly increased over the rating listed, and high rpms are not good for wind turbines.
