1, the 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 pack can meet some high-power equipment, and the direct effect of parallel mode is to make the whole battery of the current increase, and capacity is affected by the current output end,
So the direct effect of parallel is to increase the capacity of lithium batteries, in this way the capacity of the battery is often relatively large, that is, the so-called capacity lithium battery pack.
2, the application of different products Some large equipment requires a higher voltage value, because the small power of the battery pack does not work, so it is necessary to select the power Lithium battery pack. For example, we usually use the electric bicycle, it requires a voltage value is often 48V, compared to some of our life, 48V is not small. So it is necessary to use the Power Lithium battery pack to ensure the operation of electric bicycles.
And we usually go to some large supermarkets or shopping malls, some lights and standby power supply, because these devices are not very large power consumption, so the general use of capacity lithium batteries, the two in the application of the product is different.
3, internal resistance is different Power Lithium Battery's internal resistance is smaller than capacity lithium battery, to 18650 for example, 3 times times the discharge of good manufacturers generally with PDC, internal resistance of 40 or so, 5 times times the rate of discharge is generally not with a PDC resistance of about 20.
