## Series, Parallel and Series-Parallel Configuration of Batteries

Series, parallel and Series-Parallel Configuration of Batteries.

Today, we will discuss about Series, parallel and Series parallel Connection of batteries. As I received some confusing circuits about the topic, so I decided to tell something basic about it.
Now let’s begin…
Types of Battery Connection
There are three basic types of Batteries connection
(1). Series Connection
(2). Parallel Connection
(3) Series-Parallel Connection
Below is the comprehensive detail about each connection.

(1).  Series Connection of Batteries
If we connect the Positive terminal of battery to Negative and Negative to Positive Terminal Then the batteries configuration would be in Series.
Good to know:
In Series Connection of batteries, Current is same in each wire or section while voltage is different i.e. Voltage is additive e.g.V1+V2+V3….Vn = 12V + 12V = 24V,  200Ah
In below figure,.
Two batteries each of 12V, 200Ah are connected in Series. So the total effective Ampere-hour would be same while Voltage is additive (Remember that this is a Series Circuit)

(2). Parallel Connection of Batteries
As we know that if we connect the Positive terminal of battery to positive and Negative to Negative Terminal. Then the batteries configuration would be in Parallel
Good to know:
In parallel Connection, Voltage will be same in each wire or section, while current will be different i.e. current is additive e.g. I1+I2+I3…+In = 200Ah +200Ah = 400Ah, 12V.
In below figure,.
Two batteries each of 12V, 200Ah are connected in Parallel. So the total effective Voltage would be same while Ampere-hour is additive (Remember that this is a Parallel Circuit)

(3). Series-Parallel Connection of Batteries
If we connect two pairs of two batteries in series and then connect these series connected batteries in parallel, then this configuration of batteries would be called Series-parallel Connection of batteries.
In below figure,.
Six (6) batteries each of 12V, 200Ah are connected in Series-Parallel configuration.
i.e.
(1) = B1 & B2 in Series … 12V+12V = 24V 200Ah …Series Connection
(2) = B3 & B4 in Series … 12V+12V = 24V 200Ah …Series Connection
(3) = B5 & B6 in Series … 12V+12V = 24V 200Ah …Series Connection
And then the pair of these batteries are connected in parallel i.e. (1) , (2) and (3) Sets are connected in parallel
So the effective voltage and Ampere-hour would be = 200Ah+200Ah+200Ah = 24V, 600Ah. (Parallel Connection)
