Overall, it's pretty good.
Lithium battery doesn't say which one is better, it depends on the capacity. It's just that their brands are there, but there is no guarantee whether the products below are genuine, because the price of genuine products is very high, even the lithium batteries that Weitian can make are almost always falsely labeled. However, because the quality of their lead-acid batteries was indeed good in the past, many people still believe in this brand.
In addition to ternary batteries, Tafel's FFH3H0-115Ah and 136Ah lithium iron phosphate batteries have also been certified and issued by TUV Süd. At present, the energy density of a single Tafel lithium iron phosphate battery has exceeded 160 Wh/kg, and the cycle time exceeds 5,000 times. It is suitable for assembling purely electric buses and logistics vehicles.
What18650 battery brand is best?
Lithium battery ABC refers to the performance classification of lithium-ion batteries and is used to distinguish different types of lithium batteries . . Here is a brief description of each grade:
Grade A (Grade A): Grade A lithium batteries are high-quality lithium batteries with excellent performance and reliability. They generally have higher energy density, longer life, and lower self-discharge rates. Class A batteries are suitable for demanding applications such as power tools and electric vehicles.
Grade B: Grade B lithium batteries are medium-quality batteries with relatively poor performance and reliability. Their energy density, lifespan and self-discharge rate may be slightly lower than batteriesClass A. Class B batteries may be suitable for some general purpose applications, but are not suitable for scenarios requiring higher performance.
Grade C: Grade C lithium batteries are low-quality batteries with poor performance and reliability. They generally have lower energy density, short lifespans and higher self-discharge rates. Class C batteries are suitable for some low-power devices or temporary emergency use, but are not suitable for long-term high-load or high-performance application scenarios.
It should be noted that the ABC grade of lithium batteries is not a standardized classification, and different manufacturers or suppliers may use different standards for quality classification. Therefore, when purchasing lithium batteries, it is recommended to refer to dhe specifications and more detailed performance indicators to judge the quality and suitability of batteries.
18650 battery brands include LG HG2, Samsung 25R, Sony VTC4, LISHEN, BYD, BAK,etc. ?
The theoretical battery life of the 18650 is 1,000 charge cycles. Due to their large capacity per unit density, most of them are used in laptop batteries. In addition, 18650 has very good work stability and is widely used in major electronic fields.
Recommended brands:
1. LISHEN
Tianjin Lishen Battery Co., Ltd. is a main company with independent intellectual property. Rights Technical, a high-tech joint stock enterprise specializing in technical research, development, production and operationlithium-ion batteries and power batteries. The company is located in Huayuan Industrial Zone, Binhai High-tech Zone, Tianjin, covering an area of 400,000 square meters. It was established on December 25, 1997, with registered capital of 1.25 billion RMB and total assets of 600 RMB. billion.
At present, the company has an annual production capacity of 500 million Ah of lithium-ion batteries, and its products include hundreds of models divided into four series: round, square , flexible polymer and plastic packaging, and power batteries. .
2. Recommendation: Sony VTC4 2100mAh or LG HD2 2000mAh
Both can provide high current, good capacity, good voltage and low voltage when working. , their performance is very close. HB6 and HB2 can easily discharge 30A, but they are rated lower due to their smaller capacity. They falso work at very low temperatures.
3. Recommendation: LG HB6 1500mAh
HB6 and HB2 have relatively low capacities. These are the only batteries that can be used for extremely high currents. and they are also available The battery with the lowest operating temperature. Although HB2 is also very good, HB6 has a slightly lower temperature, slightly larger capacity and slightly higher voltage, so it is the champion of the 30A and above group.
4. BYD
BYD was founded in 1995 and is listed on the Hong Kong Stock Exchange and the Shenzhen Stock Exchange, respectively. It is mainly active in the securities sector. secondary rechargeable battery production business, the IT industry mainly includes mobile phones, computer parts and assembly, and the automobile industrye, including traditional fuel vehicles and new energy vehicles, and uses its own technological advantages to actively develop solar power plants and energy storage. power plants, LED and electric forklifts, including other new energy products.
5. BAK
BAK Battery Co., Ltd. was established in 2001 with a registered capital of 660 million yuan, equivalent to 82.6 million US dollars. It was listed on the NASDAQ in the United States on May 31, 2018 and is a listed company in the United States.
It is a high-tech enterprise integrating R&D, production and sales of lithium-ion batteries. The newly built BAK Industrial Park covers an area of 360,000 square meters and has more than 8,000 registered employees. The daily output of lithium batteries reaches 1.5 million units, making it one of the largest professional manufacturersls of lithium batteries in the world.
