The primary USES of 18650 batteries have?

Source: 2020 - 03 - 25 who fell hits: what is the purpose of the 1, 18650 battery? 18650 is 1000 times charging battery life theory. Because the capacity of the unit density is very big, so most of the notebook battery, in addition, in 18650, work has a good security features, widely used in each big electronic categories: often used in advanced light flashlight, portable power, wireless data transmission and electric hot clothing, shoes and portable instruments and meters, portable lighting, portable printer, industrial equipment, medical equipment, etc. The 18650 battery which brand is good? ( a) If it is less than 20 a requirement of 18650 batteries, any Suggestions? 1. Product introduction: LG HG2 3000 mah or samsung 2500 mah2 25 r. Reason: the two batteries are current superiority, capacity, the working temperature is moderate, outstanding working voltage combination. Rated power of both types of 20 a, but in 20 a discharge, HG2 power ratio r (25 Several degrees cooler than the 25 r) Higher than 15%. VTC5 and HE4 is also quite a good battery, but not as 25 r and HG2. Their low voltage and capacity, in the 20 a discharge tests. 30 q is also good, but not as good as HG2, but it is still a good battery, ranked second in this respect. ( 2) If it is 20 - 30 a 18650 battery needs, what is the introduction? 1. Introduction: SONY VTC4 2100 mah or LG 2000 mah2 HD2. Reason: both can provide high current in running, good capacity, good voltage and low temperature, the function is very close. HB6 and HB2 can easily eduction 30 a, but because their capacity is small, so in a very low position, and their working temperature is low. ( 3) If it takes more than 30 a 18650 battery, any recommendations? 1. Introduction: LG HB6 1500 mah2. Introduced reasons: HB6 and HB2 capacity is very small. They are the only can be used in high current of battery and lowest temperature of the battery. HB2 is very good also, of course, but HB6 slightly cold, slightly, slightly high voltage, is the champion of the more than 30 a and group.
