What are the correct charging methods for lithium batteries and lithium iron phosphate batteries?

The correct charging method of lithium battery Method 1. Before the lithium battery leaves the factory, the manufacturer has carried out the activation process and pre-charged, so the lithium battery has residual power, and the lithium battery is charged according to the adjustment period. This adjustment period needs to be 3~5 Fully charged and discharged times. Method 2: Before charging, do not discharge the lithium battery. Improper discharge will damage the battery. When charging, try to charge slowly and reduce fast charging methods; the time should not exceed 24 hours. The chemical substances inside the battery will be fully activated after three to five full charge and discharge cycles to achieve the best use effect. Method three, please use the original charger or the reputable brand charger, the lithium battery should use the lithium battery special charger, and follow the instructions, otherwise the battery will be damaged or even dangerous. The correct charging method of lithium iron phosphate battery pack ●It is recommended to use the CCCV charging method for charging the lithium iron phosphate battery pack, that is, first constant current and then constant voltage. The recommended constant current is 0.3C. Constant voltage recommendation 3.65. That is, 0.3C current charge in the constant current process, when the battery voltage reaches 3.65V, use 3.65V voltage constant voltage charge, when the charging current is lower than 0.1C (or 0.05C), stop charging, that is, the battery is already full. ●The charger of lithium iron phosphate battery pack is different from ordinary lithium battery. The highest termination charging voltage for lithium batteries is 4.2 volts; the lithium iron phosphate battery pack is 3.65 volts. When charging the lithium iron phosphate battery pack, it is connected to the balance charging board. Generally, it is directly charged in series from both ends. The voltage of the charger is greater than the voltage of the battery pack. ●It is best to charge the lithium battery pack at a temperature within 0-45°C. Such a temperature is more conducive to the activation of the chemical properties in the lithium battery pack and makes the charging efficiency higher. ●When you get the lithium iron phosphate battery pack and want to use it formally, you must charge it, because the lithium battery cannot be over-charged when it is stored, and over-fullness will cause serious capacity loss. Therefore, the charging precautions of the lithium battery pack are still more practical during the use of the lithium battery pack.
