Off grid expansion

Craigslist has been a blessing once again. I was able to secure another solar panel for much less than retail price.

This week's score was a BP Solar 12v/50w panel. It is in brand new condition.

I now need to re-work the mounting structure to accommodate this new panel, as it is a different size than my two Siemens panels. Once that has been done we will have a total of 136 watts of power.

So far this year, we've mowed the lawn twice, using an electric mower powered from the inverter. It has worked well, but towards the end of the job I could tell that we were getting pretty low on juice. I don't think that our batteries are in the best of condition, even though I have checked and maintained the fluid levels.

I am continuing to look around for some better storage batteries and will be patient until I do. It will have to be something local as shipping for deep cycle, or any automotive battery, is pretty expensive.

Do you have any recommendations for the best battery for the buck?
