About this item
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 3.6V-3.9V and the storage temperature must be within the range of -10°C~45°C. If not used for more than 3 months, it must be placed in an environment with a temperature of 18°C~28°C and a humidity of 65% 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 250mAh LiPo battery can be used for RAK19007+RAK4631, ESP32 development board and Other low-power IoT/DIY electronics requiring compact power solutions
