The main difference between parallel and series batteries is in voltage and capacity
Taking a lithium battery with a voltage of 3.7V and a capacity of 3000mAh as an example, it is also a two cell battery.
If it is two connected in series, the battery pack is 7.4V/3000mAh;
If it is two parallel connections, the model becomes 3.7V/6000mAh;
When connected in series, the voltage increases while the capacity remains unchanged. When connected in parallel, the capacity increases while the voltage remains unchanged (I is the current, U is the voltage)
Series circuit: Each component in the circuit is connected one by one in sequence
Calculation formula: l (total)=I (1)=l (2), U (total)=U (1)+U (2)
Parallel circuit: Each component in the circuit is connected from beginning to end and from end to end
Calculation formula: l (total)=I (1)+l (2), U (total)=U (1)+U (2)
Attention: The battery pack is connected in series by default when in use*
