First of all, lead-acid batteries (SLA) lead-acid batteries are not only cheap, but also easy to recycle. However, lead-acid batteries are sensitive to the environment and cannot be stored for a long time. If you must use an electric car to commute to work, then lead-acid batteries are not the best choice. Lead-acid battery is cheap because its weight is twice that of Ni-MH battery and three times that of lithium battery. Compared with Ni-MH battery or lithium battery with the same weight, the effective storage capacity of lead-acid battery is smaller. The service life of lead-acid batteries is only half that of nickel-hydrogen batteries or lithium batteries. If the advertisement for cheap electric bicycles doesn't say what batteries they are, then it is certain that they are lead-acid batteries. This kind of electric bicycle is very cheap, but its cost performance is not high. If the electric bicycle you want is just a toy, take it out to play occasionally, then this battery is a good choice. If not, it is best to avoid using lead-acid battery electric vehicles. ? Lithium battery? Lithium batteries account for more than 90% of the market and have become the default batteries. But to make matters worse, there are many different types of lithium-ion batteries. On the other hand, lithium-ion batteries have a longer life than other batteries and generate more power than other batteries with the same weight. The downside is that lithium-ion batteries burn easily. When the battery is charged and discharged, if the shell has scars, it will break, causing leakage, fire and even explosion. Therefore, most lithium-ion batteries are equipped with short-circuit protection circuits and explosion-proof wires. However, for a big brand manufacturer like Xinri, these are not problems. Manufacturers will always find a solution. Like all good things, this kind of battery is very expensive, and there is no sign that it will become cheaper.
Wei Chao battery is a product of Wei Chao Group. Its products include electric mopeds, electric road bikes, batteries for electric vehicles, solar and wind energy batteries, lithium batteries for electric bicycles and Jinchaowei batteries. Series products are sealed lead-acid batteries for power assistance, which are new batteries developed according to industry standards. It has the characteristics of excellent high current discharge performance, small self-discharge, high specific energy and long service life, and is an ideal supporting power supply for electric bicycles. Reliable sealing structure, no liquid leakage, high specific energy and excellent high current discharge performance. Lean liquid design, internal oxygen circulation, less water loss, strong charging acceptance and long cycle life. Applicable model: 1. Electric bicycle; 2. Light electric vehicles; 3. electric bicycles.
Tianneng battery, a battery developed by Tianneng Group, was established in 1986, located in Changxing, Zhejiang Province, the "China Green Power Energy Center" in the hinterland of the Yangtze River Delta, and mainly focused on the manufacture of environmental protection power batteries for electric vehicles. This series of batteries is specially designed and developed by Tianneng for electric mopeds and electric bicycles. This product has a number of national patent protection technologies and is the world's leading high-performance long-life lead-acid battery. Lead-acid batteries for traction are mainly used as DC power sources for electric forklifts, electric storage trucks, electric tractors, electric flatbeds and electric yachts used in industrial and mining enterprises, warehouses, docks and stations, and can also be used as supporting DC power sources in other aspects.
So which is better, Wei Chao or Heaven? There is no distinction between good and bad. It's up to you. First, how many kilometers do you run a day? If the battery of 12A runs 40 kilometers a day, the battery will be scrapped in half a year. One day 10 km, one year is no problem. Second, the charger, pulse and ordinary are not in the same class. And even ordinary ones are very different. For example, for a 48V charger, the general charging voltage is about 60V (59V), and the highest I have ever seen is about 70V, so I won't talk about the battery pressure. Third, personal riding habits, some people start the car and directly step on the accelerator (bad), while others step on the accelerator (good), which is more common and harmful to the battery, and there are many others. . . Therefore, half of the battery is good or bad on you. But ... . . . Good things are always good things, which are not comparable to ordinary goods. Two days ago, I went to repair the replaced battery. My boss recommended Tianneng battery to me, saying that the price in Wei Chao is cheaper, but if the quality is good, Tianneng will be good. Riding a bike is not bad now. By the way, the boss said that the battery I replaced can be guaranteed for 18 months. Each has its own advantages. Today, we can make batteries much earlier than Wei Chao, and we can pay attention to product quality. All products are produced by ourselves, while Wei Chao's products are processed on behalf of others. Wei Chao has done more in advertising than Tianneng. Tianneng has also started to invest in advertising in the past two years, but it is still not as much as Wei Chao.
So these two kinds of batteries have their own advantages, and either one will do. The most important thing is to take care of yourself. I hope my answer can help you!
