Multiple Batteries in Parallel
I have several regular 12v batteries that are different sizes. Can I safely hook them up in parallel without damaging any of them?

In the marine world it is very common to combine battery banks & then control them through switching. The key is having same type & condition.
For example, in my boat I had 5 gel cell group 31 batterys. They were arranged into 3 battery banks. 2 banks of 2 in parallel & 1 single. Through the switches I could use any bank or combination of banks that I pleased. I also had a 3 bank charger selectable for wet cell, AGM or gel cell.
3 of the batterys were bought together. The other 2 were bought a couple years later.
