5 ways to buy electric vehicle 4s lipo battery!

Due to the implementation of the new national standard for electric vehicles, there are also mandatory standards for the weight of electric vehicles. Then, the light and compact 4s lipo battery has a great use. In fact, the advantages of the 4s lipo battery of electric vehicles are far more than light weight. , 4s lipo battery has the advantages of long life and green environmental protection compared to the lead-acid batteries of mainstream electric vehicles. However, the price of 4s lipo battery will be more expensive. Then, since it is expensive, we must learn to choose. In order to avoid being deceived, CNHL, a professional 4s lipo battery company, has summarized several good ways to choose 4s lipo battery.

Pick 4s lipo battery Method 1: Check the appearance and packaging

4s lipo battery products can be judged from the 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.

Select 4s lipo battery method 2: look at the product battery

First check whether the battery is brand new, because there are some bad small workshops in the market that use second-hand batteries to make 4s lipo batteries. A good battery is safer, and the quality of the 4s lipo battery is better!

Select 4s lipo battery method three: detect live work

During the charging process of the 4s lipo battery, 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 the 4s lipo battery with high-quality protection board is better than that of the ordinary 4s lipo battery.

Choose 4s lipo battery method four: compare the weight

The weight of the 4s lipo battery is proportional to the capacity. If it is a polymer 4s lipo battery, if the weight difference is too large, the capacity will definitely be insufficient, but there are differences in the capacity of some batteries themselves. In addition, you can also perceive from the outer packaging whether the weight of the battery is relatively heavy. If it is heavy, it will prefer a high-quality 4s lipo battery.

Choose 4s lipo battery method five: test internal resistance and maximum current

In fact, the fastest test method to judge the performance of the 4s lipo battery is to test the internal resistance and the maximum discharge current. Good quality 4s lipo battery, very small internal resistance and large maximum discharge current. Using a multimeter with a range of 20A, directly short-circuit the two electrodes of the 4s lipo battery, the current should generally be around 10A, or even higher, and it can last for a period of time. A relatively stable battery is a good battery.
The above are several selection methods of 4s lipo battery. I hope this article can help you when you choose 4s lipo battery. More information about lithium batteries can be found below:
