As all we know, there are many types of lithium batteries, such as power lithium battery and capacity lithium battery, so what is the difference between the two lithium batteries? Let's talk about the differences here.

1. Voltage Difference

In the battery industry, when the voltage increases, the corresponding outputvoltage 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 whole battery, and the capacity is affected by the current at the output end. 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 usually larger, which is the so-called capacity lithium battery pack.

2. Applied Product Difference

Some large equipment needs a high voltage value, because the small power battery pack can not run, so we have to choose the power lithium battery. For example, the electric bicycle we usually use, its voltage value is often 48V,relative to some of our lives, 48V is not small. So you have to use lithium-ion batteries to keep the bike running. But 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, so generally use capacity lithium battery pack, the two are different in the application of products.

3. Internal Resistance Difference

The internal resistance of the power lithium battery is smaller than that of the capacity lithium battery. Taking 18650 as an example, a good manufacturer with 3 times discharge usually has PDC, with internal resistance of about 40. 5 - rate discharge is generally without PDC internal resistance of about 20.

No matter what you want to know about the batteries, you can feel free to contact us, because Bofuneng Battery is a professional manufacturer in lithium ion battery industry for 16 years, with over 90 models of battery cells, which can be assembled into different battery packs as per customer’s request.
