Always told it is not wise to mix new batteries with old batteries. Can someone tell me why?
I assume you're talking about batteries within a single bank of batteries. The batteries in a bank will equalize across the set of batteries and the weakest one will drag the others voltage down to its level.
With parallel batts only 12V batts can be used not 6v deep cycle.
There are 12V deep cycle but they usually do not have the same punch 2 in parallel compared to 2 golf carts in series.
"I have two battery banks consisting of 4 golf carts in series/parallel for each bank."
The 6v in series should be the same age.
Ok, reading this, I want to make sure I get it.
I have a house bank of 2 6 volt batteries hooked up to make a 12 volt unit. Those batteries got run down a little but are only a year old, so they still have some life.
I understand from the above that I can add in parallel another 2 new 6 volt batteries if I hook the 2 new batteries together to make a 12 volt unit. Have I got that right?
