Battery Wiring - Parallel or Series

Battery Wiring - Parallel or Series

One topic that causes a bit of confusion to most people is the concept of wiring batteries together so we thought we'd take a couple of minutes to show you how its done.

PARALLEL WIRING

If you want to increase your battery storage capacity by wiring two or more batteries together then you need to wire them in parallel. This means joining +ve to +ve and -ve to -ve.

For two 12V batteries of the same size this will double your capacity in Ah but keep the voltage the same.

SERIES WIRING

If you want to increase your battery voltage by wiring two or more batteries together then you need to wire them in series. This means joining the +ve of one battery to the -ve of the other. 

For two 12V batteries of the same size this will double your voltage but keep the capacity in Ah the same.
