The parallel voltage of the battery is unchanged, and the supply current can be increased
Battery series can increase the supply voltage, the current is unchanged
The difference between battery parallel and series is mainly the difference in voltage and capacity, take the voltage is 3.7V, the capacity is 3000mAh lithium battery, the same is two batteries, if it is two strings, the model of the battery pack is: 7.4V\/3000mAh, if it is two and the model becomes: 3.7V\/6000mAh. In series, the voltage will increase but the capacity will not change, and in parallel, the capacity will increase but the voltage will not change. But the batteries we often use are in series and parallel, such as: three series and four parallel and so on. Hope I can help you.
