Thanks in advance.
Series batteries is not a good idea.
Remember the series Christmas tree lights?
When one bulb went out, the rest followed.
Same with batteries.
Use 2 parallel 12 volt
batteries. When one goes out, your still in business. Not so, with series batteries.
Also, series batteries must be exactly the same, so that they would charge equally well.
Again, not true with parallel batteries.
