I have a wind turbine, which generates 12V/400W and two 12V batteries connected in series to have one 24V. I have two questions, is it possible to charge them from the turbine just through the 12/24V converter without using the 24V charger? The second question: Is it possible to charge them just with the 12V from the wind turbine without using the converter at all?
The batteries must be connected in series the whole time.
Thanks in advance.
Edit: The batteries are both Varta Professional DC -LFD140-12V-140AH - lead acid.
Edit2: Is there any way how to charge the batteries from the turbine?
