There is a good way to choose LiFePO4 Battery Pack

There are various types of LiFePO4 Battery Packs on the market, and the quality is also uneven. If you do not choose a good lifepo4 battery and buy a LiFePO4 Battery Pack with poor quality, it will also be a kind of harm to later use. If you want to choose a good quality LiFePO4 Battery Pack, let me teach you how to choose.

Here is the content list:

Check the appearance and packaging of the LiFePO4 Battery Pack.

Compare the weight of the LiFePO4 Battery Pack.

Test the internal resistance and high current of the LiFePO4 Battery Pack.

Test the LiFePO4 Battery Pack to work with electricity.

Look at the cells of the LiFePO4 Battery Pack.

Check the appearance and packaging of the LiFePO4 Battery Pack

First of all, LiFePO4 Battery Pack products can be judged by their packaging and appearance. Although the appearance of general products is deceptive to a certain extent, some inferior products can also be screened out from the appearance.

Compare the weight of the LiFePO4 Battery Pack

The weight of the LiFePO4 Battery Pack is directly proportional to the capacity. If it is a polymer BMS lifepo4 400Ah, if the weight difference is too large, the capacity will be insufficient. . But there are differences in the size of the capacity of some batteries themselves. In addition, you can also perceive whether the weight of the battery is relatively heavy from the outer packaging. If it is thicker, it will prefer the high-quality LiFePO4 Battery Pack.

Test the internal resistance and high current of the LiFePO4 Battery Pack

The test method to judge the fast performance of the LiFePO4 Battery Pack is to test the internal resistance and large discharge current. Good quality LiFePO4 Battery Pack has very small internal resistance and a large discharge current. Use a multimeter with a range of 20A to directly short the two electrodes of the lithium battery. The current should generally be around 10A or even higher, and it can last for some time. A relatively stable battery is a good battery.

Test the LiFePO4 Battery Pack to work with electricity

During the charged working process of the LiFePO4 Battery Pack, if the two poles of the battery are not hot after continuous discharge for about 10 minutes, it proves that the battery protection board system is perfect. Generally, the quality of a LiFePO4 Battery Pack with a high-quality protective plate is better than ordinary LiFePO4 Battery Pack.

Look at the cells of the LiFePO4 Battery Pack

Most of the batteries used in the 12V 400A LiFePO4 Battery Pack are pouch batteries and 18650 batteries, which are also relatively common materials for LiFePO4 Battery Pack batteries. First, check whether the batteries are brand new because some unscrupulous small workshops in the market use second-hand batteries to make LiFePO4 Battery Pack. Soft-packed lithium batteries, also known as polymer batteries, are batteries with gel-like electrolytes in soft packages, which can be made into various shapes. The batteries have high safety and will not explode.

The above are the matters needing attention in the selection of the LiFePO4 Battery Pack. You can choose a good battery by paying attention to the above matters when choosing LiFePO4 Battery Pack.
