I'm looking at batteries, old style lead acid. I'm thinking about going to golf cart batteries, but I'm wondering what kind of chargers they need.
I will obviously put 2 in series, but will my 12 volt charger do the trick or do I need a 6v double battery charger?
for the price I want to get golf cart as well as the amps they hold compared to a group 31 deep cycle
