What are the methods to check the quality of lithium battery equipment?

Methods to detect the quality of lithium battery equipment 1. The fastest inspection method is to test the internal resistance and maximum discharge current. Good quality lithium battery equipment has very small internal resistance and large maximum discharge current. Use a multimeter with a 20A range to directly short the two electrodes of the lithium 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. 2. Look at the appearance; the fullness of the appearance, such as the general lithium battery equipment of about 2000mAh, is relatively large. The workmanship is more delicate or the packaging is more plump. 3. Look at the hardness; you can gently pinch the middle part of the lithium battery device with your hands or moderately pinch the middle part of the lithium battery equipment. The hardness is moderate, and the no soft squeeze feeling proves that the lithium battery is a relatively high-quality battery. 4. Look at the weight; remove the outer packaging and feel whether the weight of the battery is relatively heavy, if the heavy one is a high-quality battery. 5. During the live working process of the lithium battery equipment, if the battery poles are not hot after continuous discharge for about 10 minutes, it proves that the battery protection board system is perfect. Generally, the quality of lithium battery equipment with high-quality protection board is better than ordinary lithium battery equipment.
