There are many kinds of lithium batteries, such as power type lithium battery and capacity type lithium battery, so what is the difference between the two kinds of lithium battery?  Maybe a lot of people don't know.  

1. the voltage is different  

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

2. the application of different products   

Some large equipment need higher voltage value, because the small power of the battery pack can not operate, so it is necessary to choose power lithium battery pack. For example, the electric bicycle we usually use, it requires the voltage value is often 48V, relative to some of our life, 48V is not small. Therefore, it is necessary to use the power lithium battery pack to ensure the operation of the electric bicycle.  And we usually go to some big supermarkets or shopping malls, some sign lights and backup power,  

Because the power consumption of these devices is not very large, they generally use capacity lithium battery packs, which are different in the application of products.   

3. Different internal resistance   

The internal resistance of power type lithium battery is smaller than that of capacity type lithium battery. Take 18650 lithium battery pack as an example, manufacturers with good 3-rate discharge generally have PDC. Internal resistance of about 40;  5 rate discharge generally does not have PDC resistance of 20 or so.
