Can I use a bunch of AA Batteries setup in cells in place of a deep cycle battery for green power storage? Answered
I have been looking more and more into solar and wind power generation as well as ways to store the power. I am still in the planning stages and have not yet tested anything. What I usually see in almost every green power storage guide is to use deep cycle batteries mostly of the types designed for solar, golf carts, etc. That would work fine but they are always rather expensive atleast any I have found online (if you know a cheaper source I would love to hear about it).
So my question is this could I just buy a bulk quantity of AA NiMH (the new ones without memory) or AA Lithium ion batteries and set them up in series to make cells of 8x AA per cell for 12v total then connect all cells in parallel for my battery bank? I am not sure if this would actually be more expensive as it is just an idea I had and have been unable to find someone that tried it (perhaps I am searching for the wrong thing). It seems to me this could be more effective as I could replace one battery in the cell when it goes out and be able to constantly repair the cells in that manner.
Has anyone tried this and does it work? Would it require a special charge controller unlike the usual ones sold for solar? If anyone knows of any guides that show this please share them as I would love to do more research on this before I make a decision. I think I saw once on some show that the electric car they showed was setup in this way. Anyway thank you for your assistance it is greatly appreciated!
