Hello, the selection of lithium battery parameters need to consider the following factors:
1. Battery capacity: Capacity refers to the amount of electricity that the battery can store, generally in milliampere-hours (mAh). The choice of battery capacity should be determined according to the needs of the application, such as equipment that needs to be used for a long time needs to choose a large-capacity battery.
2. Battery voltage: Different types of lithium battery voltages are different, and the corresponding lithium battery is selected according to the voltage required by the equipment.
3. Maximum discharge current: The maximum discharge current refers to the maximum current that the battery can withstand, generally expressed in magnification. The selection of batteries should be determined according to the maximum current demand of the device.
4. Charging rate: Charging rate refers to the maximum charging current that the battery can withstand, generally expressed in a multiplier. The selection of batteries should be determined according to the charging needs of the device.
5 Cycle life: cycle life refers to the number of times that the battery can be repeatedly charged and discharged, and is also an important indicator of battery life. When choosing a battery, choose a model with a long cycle life.
6. Volume and weight: The volume and weight of the battery are also factors to consider, especially for mobile devices, to choose a battery with smaller volume and weight.
Considering the above factors, choose the lithium battery parameters suitable for your device.
1, first pay attention to the battery capacity and voltage and other indicators
< br >
Battery is the main power source of electric vehicles, different capacity, power, driving distance so that electric vehicles in the price difference of 2 to 3 times. Therefore, when purchasing, we must find out how many volts and how many amps are the specific parameters of the electric vehicle battery bought.
< br >
2, secondly, we must have a clear idea of the warranty period and specific warranty content of the electric vehicle
< br >
Merchants generally promise battery warranty for one year, but the warranty \"one year\" said by merchants is measured in time: generally refers to the date of purchase, replace the new battery with a quality problem within six months, replace the old maintenance battery within six months to a year, and the problem occurs after one year of use.

Therefore, when consumers buy battery cars, they should negotiate with businesses about the specific warranty period and the corresponding content of the battery, and indicate it on the warranty card to avoid unnecessary consumer disputes in the later period.
The choice of lithium batteries is mainly from the voltage and capacity of the battery to choose from two aspects, the battery: the voltage should be the same as the use of the motor voltage, or slightly higher than the motor voltage. The capacity of the battery is in AH, and the volume with large capacity is large at the same voltage. For example, the working current of the motor is 10A and the voltage is 12V, that is 10A*12V= 120W. If you use 12V\/10AH battery motor can work for 1 hour. The rated working current of the 120W12V DC motor is about 10A, the battery energy storage for 20 minutes with the maximum power of 120W is 40Wh, the capacity required by the battery pack is about 12V4Ah, and the lithium battery is a power battery. The recommended combination is a manganese lithium polymer battery with a single core capacity of 4-5Ah, three in series, the working voltage is 3*3.7V=11.1V, and the battery weight is about 100-200g. Lithium series use to add protection plate.
