Specification BatteriesIncluded : 1 BatteriesRequired : 1 Brand : YELUFT BulletPoint1 : Reversed Polarity: These 5000mAh battery is designed with special reverse polarity (positive and negative terminals are in opposite positions to those of conventional batteries), so please be sure to check the direction of the device interface before installation to avoid damage due to the opposite connection. Please recognize the “+” and “-” markings on the battery side when installing BulletPoint2 : Safety and Reliability: Our product utilizes a cutting-edge, A-grade lithium battery system. Compared to others, it offers superior energy capacity and density, along with more stable discharge performance and an extended lifespan. Additionally, it meets the stringent UN 38.3 safety standards, ensuring both safety and reliability BulletPoint3 : Charging: It is recommended to charge with a current of 2.5A, charging to 4.2V with constant current, converting to constant voltage charging when charging to 4.2V, and finally setting at 0.02C cut-off current of 100mA, at which time the battery is fully charged. Charging with currents and voltages higher than recommended may cause problems with the battery's charging, discharging, mechanical and safety performance, and may cause heat generation or fluid leakage BulletPoint4 : Discharging: The discharge current must not exceed 5A, and the battery must be discharged within the ambient temperature range of -10℃~60℃. High current discharge will cause a sharp decrease in the battery cell capacity and cause overheating BulletPoint5 : Widely Application: With PH2.0 plug, these batteries can be used for RAKwireless WisBlock Meshtastic Starter Kit, Raspberry Pi UPS board or other projects 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.

Charging 1.1 Charging current: the charging current shall not exceed 2A. Charging with a higher current than the recommended value may cause problems with the charging and discharging performance, mechanical performance and safety performance of the cell, and may lead to heat generation or leakage 1.2 Charging voltage: the charging voltage shall not exceed 4.2V. 4.2V is the maximum limit of charging voltage, and the design of the charger shall meet this condition; if the battery voltage is higher than the rated voltage, it may cause problems with the charging and discharging performance, mechanical performance and safety performance of the battery cell, and may lead to heat generation or leakage 1.3 Charging temperature: The battery must be charged within the ambient temperature range of 0 °C ~ +10 °C (0.2C) or +45 °C ~ +55 °C (0.2C) or +10 °C ~ +45 °C 1.4 Prohibit reverse charging Connect the positive and negative terminals of the battery correctly, reverse charging is strictly prohibited. If the positive and negative terminals of the battery are reversed, it will not be possible to charge the battery cells. At the same time, reverse charging will reduce the charging and discharging performance and safety of the battery cell, and will lead to heat generation and leakage 2. Discharge 2.1 Discharge current: the discharge current shall not exceed 3A, high current discharge will lead to a drastic reduction in the capacity of the battery cell and lead to overheating 2.2 Discharge temperature: the battery must be discharged within the ambient temperature range of -10℃~60℃ 2.3 Over-discharge: During the long-term unused period, the battery may be in some kind of over-discharge state with its self-discharge characteristics. In order to prevent the occurrence of over-discharge, the battery should be regularly charged to maintain its voltage between 3.7V and 3.9V; over-discharge will lead to the loss of cell performance, battery function 3.
