At present, the brands of lithium battery electric vehicles are diversified, charging for 6-8 hours, driving for 30-45 kilometers depending on the battery capacity, and the weight is only about 1/5 of that of lead-acid batteries. The biggest advantage of lithium battery electric bicycle is its long life. It has the characteristics of non-activation and memory effect.
Disadvantages of lithium batteries:
The high price of lithium battery electric vehicles is due to lithium batteries. The dynamic performance of lithium batteries needs to be improved. Compared with lead-acid batteries, lithium batteries are much worse in charge and discharge fluctuation resistance, which is also one of the major symptoms of the current high-power vehicles' failure to effectively use lithium batteries, resulting in a decline in durability.
Advantages of lead-acid batteries:
Lead-acid batteries are easy to charge, so they can be used after a little repair. Lead-acid batteries are cheaper than lithium batteries and can be recycled for reverse repair. Lead-acid batteries have their own recycling skills. After being worn out, you can go to the electric car shop to trade in the old one for the new one, and make up the difference for a new battery, so as to minimize the loss, which is no small benefit to users.
Disadvantages of lead-acid batteries:
Large volume and weight, limited battery capacity and short service life. Lead-acid batteries generally have memory within 400 times of deep charge and discharge, and their service life is about two years.
There are many kinds of lithium battery electric vehicles, among which Giant, Taixiang, Mager, Yadea and Emma are all good choices.

How to choose batteries for electric vehicles;
1, look at the brand
As the saying goes, honest management will last forever. An honest manufacturer not only has guaranteed product quality, but also has more perfect after-sales service, which is unmatched by small brands or small businesses. Regular businesses not only have invoices, after-sales service cards and other products and services that can help users solve their worries, but also have better enthusiastic, patient and caring after-sales service.
2, look at the user evaluation
As we all know, it is not easy to establish and exist a brand, especially in today's society with such fierce competition. If the product brand quality is not good or there are places that make consumers dissatisfied, it will soon be eliminated, and the ones that can survive must be of good quality. User evaluation is not only to judge the quality of a battery brand product, but also to judge its cost performance.
Step 3 look at the quality
The quality of electric vehicle battery is the key. Needless to say, everyone knows that a good battery for electric vehicles can bring a lot of convenience to users. It can make your electric car travel farther, start faster, have a longer life, have more stable performance, charge faster and store more electricity.
Step 4 look at the date
The longer the factory date of the battery, the shorter the battery life. The service life of the battery is limited, and putting it aside indefinitely in a limited time will only waste the capacity of the electric vehicle battery, so many businesses will sell the battery within the latest date, so users should also pay attention to the factory date when purchasing.
