Lithium batteries and lead-acid batteries have their own advantages, and you should choose them according to your own situation.
1. The advantages of lithium batteries are their small size, long life and numerous recharge cycles. Friends who live in rental houses can take the batteries apart and take them upstairs to recharge. are also environmentally friendly, but the price is expensive, starting at 1,000 yuan, and a good one costs more than 2,000 yuan. If it's better, the battery is more expensive than the car.
2. Lead-acid batteries are large and bulky. Generally, the body with strong battery life is also relatively heavy, the price is relatively cheap, and the service life is not long. Typically, it may need to be replaced for more than a year. Depending on your specific daily usage, you canusually replace it with a new one for a few hundred yuan. Lead-acid batteries are mainly used in electric motorcycles, while lithium ones. batteries are used in national standard electric bicycles.
Things to note when choosing electric vehicle batteries:
1. Lead-acid batteries have environmental problems. Lead-acid batteries cause pollution during the production process. If recycled, misuse can also lead to pollution; Lithium batteries are relatively greener and more environmentally friendly. And under the same conditions, lead-acid batteries generally can be deeply charged and discharged within 300 times, and their service life is about two years. Lithium batteries are very durable, consume slowly, can be charged and discharged more than 500 times, and have a long durationtwice as long as lead acid batteries.
2. An ordinary set of 60V 20Ah lead-acid batteries often weighs more than 35kg, and lead-acid batteries also have the disadvantage of low energy density, which not only increases the weight of the vehicle, but also increases the weight The battery will also affect the vehicle's range.

Which is better, a lead acid battery or a lithium battery?
Reasons why electric vehicles spontaneously combust when entering the elevator are: the packaging of the electric vehicle lithium battery is damaged or the battery inside the film is seriously damaged, the quality of the electric vehicle lithium battery is problematic, and the temperatureThe temperature of the electric vehicle's lithium battery is too high.
1. The packaging of the lithium battery for electric vehicles is damaged or the film inside the battery is seriously damaged: so this film can protect the battery when the battery is hit hard or. pierced by other sharp objects, the battery separator will be damaged, which is also one of the reasons why lithium batteries explode and cause spontaneous combustion of electric vehicles.
2. There is a problem with the quality of lithium batteries for electric vehicles: in order to reduce the production cost of lithium batteries, a few manufacturers use other waste materials to produce lithium batteries. This type of lithium battery does not have brand certification or quality certificate and is a "three no" product among lithium batteries. This type of battery cannot be guaranteedr safety and may leak and explode during use, causing spontaneous combustion in electric vehicles.
3. The temperature of the lithium battery of the electric vehicle is too high: the electric vehicle may choose an unmatched battery charger when charging. The charger frequency is too high and the output current is too large, which. will cause the lithium battery to heat up. If it stays for a long time, it will damage the battery. If it is damaged when entering the elevator,It will explode on impact, causing the electric vehicle to spontaneously ignite.
Risks related to battery cars entering the elevator
1. Driving electric cars upstairs can easily cause disasters. Driving electric cars upstairs can cause fires, making this impossible. escape quickly, let alone rescue, will affectevacuation in the event of fire.
2. When a battery car enters an elevator and a fire breaks out as soon as the door is closed, everyone in the elevator will suffer.
3. Electric vehicles enter the elevator and occupy the elevator space, which greatly reduces the efficiency of the elevator and affects the normal use of the elevator by other owners.
4. If electric vehicles often enter and exit the elevator, they will inevitably collide with the elevator, which increases the failure rate of the elevator and accelerates its aging.
Lithium batteries and lead-acid batteries are currently commonly used battery types for electric bicycles. They each have their own advantages and disadvantages. The best solution depends on individual needs. user.
Advantages of lithium batteries: the bestLithium eries have smaller size, lighter weight, higher energy density, longer life, higher performance, higher safety and better usability. Lithium batteries can use fewer battery packs, smaller size, lower cost, less maintenance, higher reliability and higher feasibility.
Advantages of lead acid batteries: 1. Lead acid batteries are relatively cheap, inexpensive and much cheaper than lithium batteries. 2. Lead-acid batteries have good thermal stability and can withstand temperature changes and maintain good performance even at high temperatures.
