The charger of lithium iron phosphate battery is different from ordinary lithium battery. The maximum termination charge voltage of a lithium battery is 4.2 volts; The lithium iron phosphate battery is 3.65 volts. The safe operating voltage range of lithium battery is 2.8~4.2V, below or above this voltage range, the lithium ions in the battery become very unstable, and even cause accidents. In order to ensure that the lithium iron phosphate battery is in a safe range, a special charger is required. These chargers automatically adjust the charging mode according to the current state of the battery.

● It is recommended to use CCCV charging mode for lithium iron phosphate battery, that is, constant current before constant voltage. Constant current 0.3C is recommended. The recommended constant voltage is 3.65. that is, 0.3C current charge during the constant current process. When the battery voltage reaches 3.65V, 3.65V voltage constant voltage charge is adopted.

● When charging, the charger is best to choose the original special charger, otherwise it will affect or damage the lithium iron phosphate battery.

● Avoid charging at too high a temperature, if the lithium iron phosphate battery is used in an environment above the specified operating temperature, that is, 35°C, the battery's power will continue to decrease, that is, the battery's power supply time will not be as long as usual.
For lithium battery charging in fact, the requirements are also quite high, such as the current is too large will soon be full, so not only not durable and will also accelerate the aging of the battery, that is, people often say virtual electricity. And too slow, waste time. So the general rechargeable battery time will be controlled at about 8-10 hours. For example: charging time = battery capacity\/charging current 1A=1000MA For example, a 60A battery can be filled in 10 hours with a charger with 6A current. The 6A battery, with a 500MA charger, can be fully charged in 12 hours. Got it
