Specification BatteriesIncluded : 1 BatteriesRequired : 1 Brand : YELUFT BulletPoint1 : Charging Method: The recommended charging current is 0.2A, the maximum is not more than 1A. The discharge current is recommended 0.55A, and the maximum is not more than 3A BulletPoint2 : Overcharge Protection: When charging the battery, when the voltage reaches the highest battery voltage (4.2V), the protection board will automatically power off and shut down, indicating that it will not continue to charge when fully charged, form an overcharge protection BulletPoint3 : Over-discharge Protection: When the battery is about to run out and the voltage is as low as 3.0V, the protection board will also be turned off and can no longer be discharged, forming an over-discharge protection effect BulletPoint4 : Short Circuit Protection: When an accidental short circuit occurs, the protection board will automatically shut down within a few milliseconds and will not be powered on again. Note that the cell is short-circuited (not through the protection board). The protection board will also fail due to continuous high current, or the components are heated and damaged BulletPoint5 : Note: The battery overcurrent protection is not a panacea, do not continue to charge and discharge the current and voltage with a large current beyond the range, otherwise the protection board will be damaged and invalid BulletPoint6 : Storage: When the battery is not used for a long time, it may be in a certain over-discharge state due to its self-discharge characteristics. To prevent over-discharge, the battery should be charged regularly to maintain its voltage between 3.7V and 3.9V; over-discharge will lead to loss of battery performance and battery function BulletPoint7 : In view of the original design, we have added a new product which is the battery extension cable, it can be extended and connected between the battery and the port inside the battery compartment. The purpose is to increase the length from the port of battery compartment so that the battery can be charged without pulling Battery Cable Port out from this little case manually. BulletPoint8 : In addition, our sales set is also packaged with an USB charging cable. When the battery extension cable is removed, and connect this USB cable with Battery’s Cable,so that you can charge it,Lightly and Directly.
