48V electric vehicle batteries typically consist of 13 3.7V lithium batteries connected in series to form a battery pack.
48V battery cars have two configurations depending on the model, one is equipped with 12V12AH (amp-hours) and the other is equipped with 12V20AH. The external dimensions of 12AH (mm) are 150 cm long, 98 cm wide and 95 cm high, and the individual weight is approximately 4.5 kg. The external dimensions of 20AH (mm) are 181 cm long, 77 cm wide and 170 cm high. Each weighs approximately 7 kg. There are also a few manufacturers that offer 12V17AH batteries, each weighing around 6kg.
Compared with 12v12000 mAh lithium battery and 12v12ah lead acid battery, which one has larger capacity and lasts longer?
Equal to twelve cells.
The quality of the battery directly determines the mileage and safety of the wheelchair.The batteries currently used in electric wheelchairs on the market are divided into lithium batteries and lead-acid batteries. The battery of an electric wheelchair is an extremely important part of it and the battery life determines the lifespan of the electric wheelchair.
The 12V12A battery is broken. How many amps of 12V can be used to replace it?
The average voltage of a single cell of a lead-acid battery is 2V, and the average voltage of a single lithium battery is 3.7V. Due to different materials, the The activity of lead-acid batteries is not; as high as that of lithium batteries, therefore the capacity of a lithium battery in the same volume Greater than lead acid batteries; (lead acid batteries are bulky) Lithium battery platform is not as stable as lead acid batteries.
1. Environmental protection, bLithium batteries have no (non-absolute) pollution, while lead-acid batteries are polluted by heavy metal lead
2. Safety, power supply of lithium batteries (lithium manganate). , lithium iron phosphate), the safety of different materials is different. Lead-acid battery technology is quite mature and is safer than lithium batteries.
3. The specific energy, mass ratio, and specific volume capacity of lithium batteries are approximately 40% higher than those of lead-acid batteries.
4. In terms of price, the price of a lithium battery of the same capacity is more than twice that of a lead-acid battery
5. Common lithium iron phosphate can be charged 1,500 times. There is no memory effect and the storage capacity is about 85% after 1500 times charging, while the lead-acid battery is about 500 times and the memory effect is obvious. >
6. Self-discharge rate, the monthly self-discharge of lithium batteries is <3% for lead-acid batteries, the difference is obvious
7. In other words, for batteries of the same capacity, under high current discharge, lithium batteries will discharge about 30% more than lead acid batteries
8, the platform of voltage, lithium battery voltage platform is >3V, lead. -The acid battery is 2V. If the capacity is the same, the same electrical appliances are used, the duration of use is the same. It's just that the lithium battery has a longer lifespan.
Of course, the best is to use the same type of battery. should be. The same 12 V, 12 amp battery. It would be a good idea to replace him with such a clerk. I really can't find one that fits me.. It's just a slight difference, so it's not a big deal. Of course, the battery still needs 12 V and the current littlet be slightly larger or smaller. This is approximately 12 amps.
