Howdy !!
I had a reader ask how to connect two 6-volt golf cart batteries to replace an RV marine 12-volt unit. Tell the truth I thought about just sending him a private letter but then got to thinking that if one person had the question then likely more folks had the same question so here is the answer.
The little diagram here shows the connections for serial and parallel connections.
Parallel connections increase the amperage, for example, two 100-amp batteries connected in parallel will have a potential of 200-amps. Batteries connected in series increase the voltage so two 6-volt batteries in series will deliver 12-volts.
You can also hook two 6-volt batteries in series then the set into a parallel connection to double the voltage and the amperage. Thanks for the question John !
Hope this helps !
