Which company is best for electric vehicle batteries?
The heart of an electric car or moped is the battery located under the car, so which battery is best is a very important question. The battery is one of the most important components of an electric bike. Major electric vehicle manufacturers are also investing in batteries. Make a big deal out of it. For example, Xinri Electric Vehicles, a giant in China's electric vehicle industry, has invested heavily in the research and development of high-efficiency batteries in recent years. Today, most Xinri electric vehicle models use the most environmentally friendly and efficient lithium batteries. So, how to choose an electric car based on its battery?
First, lead-acid batteries (SLA) Lead-acid batteries are cheap and easy to recycle. However, lead-acid batteries are environmentally sensitive and cannot be stored for long periods of time. If you must use an electric vehicle for your trips, lead acid batteries are not the best choice. The reason lead-acid batteries are cheap is that they weigh twice as much as nickel-metal hydride batteries and three times as much as lithium batteries. Lead-acid batteries have less efficient storage capacity than nickel-metal hydride or lithium batteries of the same weight. Lead-acid batteries last only half as long as nickel-metal hydride or lithium batteries. If an ad for a cheap electric bike doesn't indicate what type of battery it has, chances are it's lead acid batteries. These electric bikesare very cheap, but they are not profitable. If the electric bike you want is just a toy that you can take out occasionally for fun, then this type of battery is a good choice. Otherwise, it is best to avoid electric vehicles with lead-acid batteries. ?Lithium Batteries?Lithium batteries account for over 90% of the market share and they have become the default battery. But to make matters worse, there are many types of lithium-ion batteries. Lithium-ion batteries, on the other hand, last longer than other batteries and produce more power than other batteries of the same weight. On the negative side, lithium-ion batteries are easy to burn. When the battery is charged and discharged, if the case is damaged, it will rupture, causing leakage, fire or even explosion. Therefore, most lithium-ion batteries have built-in protection circuits.e short circuits, as well as explosion-proof wires. However, this is not a problem for big brands like Xinri Electric Vehicles. Manufacturers will always find a way to solve it. Like all good things, this type of battery is very expensive and there are no signs of getting cheaper.

Tianneng Battery is a battery developed by Tianneng Group. The group was founded in 1986 and is located in Changxing, Zhejiang Province, China's "Green Energy Center" in the hinterland of the Yangtze River Delta. mainly manufactures environmentally friendly power batteries for electric vehicles. This battery series is specially designed and developed by Tianneng for electric mopeds and electric bicycles. OwnerFeaturing multiple national patent protection technologies, it is a world-leading high-performance, long-life lead-acid battery. Lead-acid traction batteries are mainly used as DC power supplies for electric forklifts, electric storage trucks, electric tractors, electric flatbed trucks, electric yachts, etc. used in industrial and mining enterprises, warehouses, docks and stations, and can also be used as support for DC power supplies in other aspects.
So which is better, Chaowei or Tianneng? There is no distinction between good and evil. It mainly depends on you. First, how many miles do you drive per day? If you use a 12A battery to travel 40 kilometers per day, the battery will be discarded in six months. 10 kilometers per day, no problemfor one year. Secondly, the charger, pulse charger and regular charger are not of the same quality. And there is a big difference between the ordinary ones. For example, for a 48V charger, the charging voltage is usually around 60V (59V), and the highest I've seen is around 70V, not to mention the strain on the battery. Third, personal driving habits. Some people start the bike and accelerate to maximum (bad), while others accelerate to minimum (good). This is more common among us and is more harmful to the battery, and there are many others. . . . So half of the battery quality depends on you. but. . . . . Good things are always good things and cannot be compared to ordinary goods. I went to a repair shop to replace the battery two days ago. The boss recommended Tianneng batteries to me. He said Chaowei prices are mThey are less expensive, but the quality of those from Tianneng is better. I ride pretty well now. By the way, the battery I replaced had an 18 month warranty. Each has its own merits. Tianneng has been manufacturing batteries much earlier than Chaowei. Tianneng pays attention to the production quality of products. All products are produced by itself, while Chaowei's products are processed by OEM. Chaowei advertises more than Tianneng. Tianneng has also started to invest in advertising in the past two years, but it is still not as much as Chaowei.
Therefore, each of these two batteries has its own advantages, and either one can be used. The main thing is to take care of yourself. I hope my answer can help you!
There are still many brands of electric vehicle batteries on the market today, such as Tianneng, Chaowei, Changxin, Jingqiu, Haibao, andvs. These are all well-known brands of lead-acid batteries. . , but I personally think that when you buy lead-acid batteries, you do not have to buy big-name batteries, as long as they are produced by regular manufacturers, because the development of lead-acid batteries has a history of more than 100 years, and the technology is very mature, therefore varied. Products made by major manufacturers are basically the same in terms of quality. So what you need to consider at this stage is the price, after-sales and service, and how much it costs. These days, batteries usually have a warranty period, so good after-sales service is king.
Based on the battery product quality, after-sales service and price, we recommend a very good lead acid battery brand: Changxin Battery.
As an old lead-acid battery production group, Changxin Battery johas an excellent reputation and quality and has been praised by the market for many years. As a high-end product in lead-acid batteries, Changxin graphene series adopts more scientific direct-connected row structure, improved formula with higher energy density and higher technology content, bringing longer life. longer life, longer battery life and more stable performance.
