Buy lithium battery or lead acid for electric car?

I think the two kinds of batteries have their own advantages and disadvantages, but now more lithium batteries are used in electric vehicles.

1, the price of lead-acid batteries of the same model will be lower than that of lithium batteries, which means it will be more cost-effective to replace a group of batteries and choose lead-acid batteries.

2. From the point of view of stability. At present, the lead-acid battery technology is mature and various products are relatively stable.

Lead-acid battery is big and heavy. Usually, the body with strong endurance is also heavier and has a short life.
