Are electric bicycles better with lithium batteries or lead-acid batteries?

Needless to say, in many places, lithium batteries are stronger than lead-acid batteries. For the same capacity, the volume of lithium batteries is less than 70% of lead-acid batteries, and the weight of lithium batteries is less than 40% of lead-acid batteries, so lithium batteries can do it. The cruising range is much longer than that of lead-acid batteries. The charge-discharge cycle of lithium batteries is more than 600 times, relatively durable. Lead-acid batteries have small capacity, large volume, and a much shorter service life than lithium batteries. The charge-discharge cycle cycle has also decreased, and the lifespan is shorter, generally used for one year. A little more may be broken. 2. The price The price of lithium batteries is about 2-3 times that of lead-acid batteries. Generally, an electric vehicle with a lead-acid battery costs a few hundred yuan to replace the battery, while a lithium-ion battery can cost thousands of yuan at any time. This is for the average wage earner. , It's not a small expense. Moreover, lithium batteries have almost no recycling value. Lead-acid batteries are broken, and you can replace them with some money. This way, although lithium batteries have a long life, they don’t really take much advantage compared to the recycling of lead-acid batteries. Up. 3. Reliability Although the lithium battery has a large capacity, it is too lively, delicate, slightly disturbed, and may be broken. Therefore, a reasonable battery management system must be in place, which requires temperature and vibration. If the design is not good, or the quality of the battery core is defective, or if it is used improperly, it may cause fire and explosion. For the average person, it is indeed a scare thing. Moreover, the lithium battery cannot be discharged at a high current, that is, the instantaneous output current cannot be so large, so the advantages of power are not obvious. In comparison, lead-acid batteries are in use, and it seems that many people have no major problems in series and parallel connection. If the capacity drops, just add some water or repair it, and you will be refreshed, and there is no need to worry about fire and explosion. (Of course there may be problems with overcharging) 4. Convenience. If you can’t buy a tram to ride, you can’t expect an engineer to follow your butt to help you. The lead-acid battery is broken, just buy the battery and replace it, at most It's just not far. The management system of each lithium battery is different. If it is broken, it is really difficult for you to repair it. This thing is dangerous, so it is often sent back to the manufacturer for repair or replacement. Not to mention the travel cost, it is still a trouble to delay the time. Thing up. V. Looking forward, ordinary people will choose products from the perspective of cost performance. Lithium batteries are not good enough for lead-acid batteries, which is the actual comparison after considering various factors. Look at those low-speed electric vehicles equipped with lead-acid batteries. They are also very prosperous. The regular so-called new energy vehicles do not sell well without them. This is also the truth. Disclaimer: Some pictures and content of articles published on this site are from the Internet. If there is any infringement, please contact to delete.
