Reversed Polarity: These 8000mAh 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
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
Charging: It is recommended to charge with a current of 2A, 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 160mA, 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
Discharging: The discharge current must not exceed 3A, and the battery must be discharged within the ambient temperature range of -10℃~45℃. High current discharge will cause a sharp decrease in the battery cell capacity and cause overheating
Widely Application: With PH2.0 plug, these batteries can be used for RAKwireless WisBlock Meshtastic Starter Kit, Raspberry Pi UPS board or other projects
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
