1, power lithium battery and capacity lithium battery voltage size is different

In the battery industry, the voltage increases, the corresponding output voltage will also increase, so that the power type lithium battery can meet some high-power equipment; The direct effect of parallel connection is to increase the current of the entire battery, and the capacity is affected by the current of the output terminal. Therefore, the direct effect of parallel connection is to increase the capacity of the lithium battery. The capacity of the battery connected in this way is often large, which is the so-called capacity lithium battery.

2, power lithium battery and capacity lithium battery applications of different products

Some large equipment requires a high voltage value, because the small power of the battery pack can not operate, so it is necessary to choose the power type lithium battery pack. For example, we usually use the electric bicycle, it requires the voltage value is often 48V, relative to some of our life, 48V is not small. So it is necessary to use the power type lithium battery pack to ensure the operation of the electric bicycle. However, we usually go to some large supermarkets or shopping malls, some sign lights and backup power supply. Because the power consumption of these devices is not very large, we generally use capacity lithium battery packs, which are different in the application of products.

3, power lithium battery and capacity lithium battery internal resistance is different

The internal resistance of dynamic lithium battery is smaller than that of capacity lithium battery. Take 18650 as an example. 5 times the discharge is generally not PDC internal resistance of 20 or so.
