YELUFT 2pcs 3.7V 1200mAh 803048 Lithium Polymer Battery 1S 1C LiPo Rechargeable Battery with Protection Board, Micro PH2.0 Plug Compatiable with ESP32($12.99Value)

Description

Safety and Reliability: Our product utilizes a cutting-edge, A-grade lithium battery system. Compared to others, it offers superior 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 Protection Mechanisms: When the charging voltage reaches the highest battery voltage (4.2V), the protection board will automatically power off, it will not continue to charge; when the voltage drops below 2.75V, the protection board will also turned off to prevent deep discharge of the battery. Overcharge and overdischarge can lead to the loss of cell performance and battery function Prohibit Reverse Charging: Connect the positive and negative poles of the battery correctly and strictly prohibit reverse charging. If the positive and negative terminals of the battery are reversed, the battery cell cannot be charged. At the same time, reverse charging will reduce the charging and discharging performance and safety of the battery cell, and may cause heating and leakage Storage: When not in use for a long time, please keep the battery voltage between 3.7V-3.9V and the storage temperature must be within the range of -20°C~45°C. If not used for more than 3 months, it must be placed in an environment with a temperature of -20°C~35°C and a humidity of 75% RH. We recommend charging the battery every 3 months after receiving it and storing it in a cool and dry place Widely Application: With Micro PH2.0 plug, these 1200mAh LiPo battery can be used for RAK19007+RAK4631, ESP32 development board and Other low-power IoT/DIY electronics requiring compact power solutions 1. Charging
1.1 Charging Current: the charging current shall not exceed 1.2A. 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 battery cell, and may lead to heat generation or leakage
1.2 Charging Voltage: the charging voltage shall not exceed 4.20V. 4.20V is the maximum limit of charging voltage, if the voltage is higher than the rated voltage value, it may cause problems of 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 shall be charged within 0°C~45°C
1.4 Prohibition of 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 The battery shall be discharged at less than 1.2A. High discharging current may reduce the discharging capacity significantly or cause over-heat
2.2 The battery shall be discharged within -20°C~60°C
2.3 It should be noted that the cell would be at over-discharged state by its self-discharge characteristics in case the cell is not used for long time. In order to prevent over-discharging, the cell shall be charged periodically to maintain between 3.7V and 3.9V. Over-discharging may causes loss of cell performance, characteristics, or battery functions
