How To Connect Batteries In Series & Parallel
With a parallel battery connection the capacity will increase, however the battery voltage will remain the same. Batteries connected in parallel must be of the same voltage, i.e. a 12V battery can not be connected in parallel with a 6V battery. It is best to also use batteries of the same capacity when using parallel connections.
