Are 48v20ah electric vehicle batteries the same size as 48v80ah?

They are definitely different sizes and weights. This is similar to the fact that the quantity and weight of 5 L of water and 10 L are different.

Whether it is lead-acid or lithium battery, with the same material and voltage, the larger the capacity, the larger the volume and weight. The capacity of 20AH and 80AH differs by 4 times. the volume and weight will definitely be very large.

Take the ternary material lithium battery as an example. Typically, a 48V lithium battery has many 3.7V cells connected in series. As for capacity, different capacities are obtained. parallel connection.

The lead-acid battery consists of four 12V lead-acid batteries connected in series on one side. The capacity of each battery is connected in series through lead-acid battery packs of different capacities.

What does the 60v20ah battery mean?

Although there are manytwo types of batteries on the market, including nickel batteries, zinc batteries, lithium batteries and lead-acid batteries, even In recent years, there are new graphene battery technology, but the main ones used in Electric vehicles are lead-acid batteries and lithium batteries are the most widely used and have the longest usage life, while lithium batteries are a rising star. and have been favored by many car models in recent years. So when we buy electric vehicles, is it better to choose lithium battery electric vehicles or lead acid battery electric vehicles? The old master tells you, you will know after comparing these 4 aspects.

Cost comparison between lithium batteries and lead acid batteries

If we only look at the price when buying a car, the batteriesLead-acid batteries are the first choice, because the price of lead-acid batteries is generally more than half that of lithium batteries. Additionally, once lead-acid batteries are discarded, they still have a high recycling value, which is estimated to be around a quarter of the purchase cost. However, lithium batteries basically do not have a high recycling rate. value, and most companies will not recycle them.

Technical comparison between lithium batteries and lead-acid batteries

If you are considering batteries with more mature technology, lead-acid batteries may be your first choice. Lead-acid batteries have been used for a hundred years. and the technology can be considered very mature. Although lithium battery technology is relatively mature, it is still a relative newcomer compared to lead-acid batteries. Additionally, all electric vehicles that spontaneously combust aremainly lithium batteries, which shows that it still exists. certain disadvantages in the maturity of the technology.

Parameter comparison between lithium batteries and lead-acid batteries

The above two points show that lead-acid batteries have the advantage, and the following two points are the main reasons why lead-acid batteries lithium can become a rising star. According to the parameter comparison, the first choice is the battery capacity: lithium batteries have higher average voltage and capacity density than similar batteries, lithium batteries have larger capacity and number full charge and discharge time of lithium batteries exceeds 500 times. The number of full charge and discharge times of lead-acid batteries is about 350 times. In other words, lithium batteries will be even more disabled.

Practical comparisonthan between lithium batteries and lead-acid batteries

For batteries of the same size, lithium batteries are more than half lighter than lead-acid batteries. Nowadays, light electric vehicles use lithium batteries, which are very popular. People love it. In addition, lithium batteries also have the advantages of longer life and faster charging, the main reason why lithium batteries are better than lead-acid batteries.

After listening to some comparisons between lithium batteries and lead acid batteries by the master, I believe you already have a suitable battery choice for you. In fact, since these two batteries can stand out among many batteries, it means that they are both. They have certain advantages, and there is no better one. We choose the one that suits us based on our own needsoins. The one that suits us best is the best.

The 60v20ah battery is: 60*20vah=1200WH, 1000W is the power of the car, or 1000 watts. If the capacity of the lithium battery is 1000 mAh, then the charge and discharge current is 1000 mA. When the maximum battery voltage is 4.2V and placed at 3.0V, the capacity released is the true battery capacity.

Battery capacity refers to the amount of electricity stored in the battery. The battery capacity unit is “mAh”, and the Chinese name is mAh. When measuring large capacity batteries such as lead-acid batteries, it is usually expressed as "Ah", the Chinese name is An hour, 1Ah=1000mAh. If the rated capacity of the battery is 1300 mAh, that is, a current of 130 mA discharges the battery, the battery can continue to work for 10 hours.

Detailed information

Precautionons of use of lithium batteries

1 Storage requirements: at a temperature of 20 ± 5 ℃ and at a temperature of 20 ± 5 ℃. humidity of In not more than 50% of environments, air and water vapor should be avoided during transportation to corrode the aluminum foil;

2. The product is divided into two types, A and B. The key characteristics of each are as follows: type A is black in appearance, the conventional coating thickness is 4-8μm on both sides, and the conductive performance are more exceptional; model B has a light gray appearance, the conventional coating thickness is 2-3μm on both sides. on both sides, the coating area can be welded with fewer layers and can be ultrasonic welded directly in the coating area. , and is only suitable for welding laminated battery tabs (maximum 2-3 pole pieces)), but the ultrasonic power and time requiredattempt precise adjustment;

4. is worse than that of aluminum foil, so the belt speed and baking temperature should be adjusted appropriately when coating

5. This product can significantly improve the overall performance of lithium batteries and capacitors, but it cannot be used as the main factor to change some aspects of battery performance, such as battery energy density, high and low performance. low temperature, high voltage, etc.
