Analysis of several good ways to choose lithium-ion batteries

Choose lithium-ion battery method one: check the appearance and packaging You can judge lithium-ion battery products from the packaging and appearance. Although the appearance of general products is deceptive, some inferior products can also be screened out from the appearance. The second method of choosing lithium-ion batteries: first check whether the battery cells are brand new, because there are some bad small workshops on the market that use second-hand batteries to make lithium-ion batteries. Good batteries have higher safety and the quality of lithium-ion batteries is better! Choose the lithium-ion battery method three: test live work. During the live working process of the lithium-ion battery, continue to discharge for about 10 minutes. If the battery poles are not hot, it proves that the battery protection board system is perfect. Generally, the quality of the lithium-ion battery with a high-quality protection board Better than ordinary lithium-ion batteries. Choice of Lithium-ion battery method 4: Comparing weight The weight and capacity of lithium-ion batteries are directly proportional. If it is a polymer lithium-ion battery, if the weight difference is too large, the capacity will definitely be insufficient, but there are differences in the size of the capacity of some batteries. In addition, you can also feel the weight of the battery from the outer packaging. If the weight is heavy, it is biased towards high-quality lithium-ion batteries. Method 5 for choosing lithium-ion batteries: detecting internal resistance and maximum current In fact, the fastest way to determine the performance of lithium-ion batteries is to detect internal resistance and maximum discharge current. Good quality lithium-ion batteries have very small internal resistance and large maximum discharge current. Use a multimeter with a 20A range to directly short the two electrodes of a lithium-ion battery. The current should generally be about 10A, or even higher, and it can be maintained for a period of time. A relatively stable battery is a good battery.
