Battery in Series - Parallel Connection

Connecting Batteries to Increase Total System Power

Series Connections

To increase 6 volt battery voltage to 12 volts, connect 2 6 volt batteries in series.

This will not increase the battery system capacity.

Series Example:

1. Two 6 volt deep cycle batteries rated at 225 amp hours connected in series.

System voltage : 6v + 6v = 12 volts

System Capacity = 225 amp hours (ah)

 

Parallel Connections

To increase battery capacity, connect 2 6 volt or 12 volt batteries in parallel.

This will not increase the battery system voltage.

Parallel Example:

1. Two 6 volt deep cycle batteries rated at 225 amp hours in parallel.

 

 

 

 

System voltage : 6 volts
System Capacity = 225 ah + 225 ah = 450 amp hours (ah)

 

Series-Parallel Connections

To increase both battery capacity and voltage, connect 4,  6 volt batteries in series and parallel.

This will increase the battery system voltage and capacity and is a great idea for dry camping.

 

 

Series + Parallel Example:

1. Four 6 volt deep cycle batteries rated at 225 amp hours connected in series-parallel.

 

 

System voltage : 6v + 6v = 12 volts
System Capacity = 225 ah + 225 ah = 450 amp hours (ah)
