3.7V 리튬 배터리를 충전하려면 얼마나 많은 전압을 사용해야합니까? Posted by batterymanufactory.com
Generally, a 3.7V lithium battery needs to have a "protection circuit board" for overcharging and overdischarging. If the battery does not have a protection circuit board, it can only be charged with a voltage of about 4.2V, because the ideal full charge voltage of a lithium battery is 4.2V. If the voltage is exceed 4.2V, the battery may is damaged, it is necessary to monitor the condition of the battery at the same time when charging with this method. With the protection circuit board, you can use 5V to charge (4.8V to 5.2V can be used), the USB 5V charger of the computer or the 5V charger of the mobile phone can be used. 3.7V battery, charge cut-off voltage 4.2V, discharge cut-off voltage is 3.0V. Therefore, when the open circuit voltage of the battery is lower than 3.6V, it should be able to charge. It is best to use 4.2V constant voltage charging mode, you don't need to pay attention to the charging time. Charging with 5V is prone to danger of over...
