MakerHawk 3.7V 4000mAh LiPo Battery Rechargeable 1S 3C 124065 Lithium Polymer Battery with Protection Board Insulated Rubber Tape, Micro JST 1.25 Plug for Arduino ESP32 Development Board (1 Pack)

MakerHawk adopts a brand-new A-grade lithium cobalt oxide battery system, which, compared to ternary system batteries, not only provides higher energy and higher density but also ensures more stable discharge performance and longer lifespan. It also complies with UN 38.3 standards certification, ensuring safety and reliability.
Over-Discharge Protection: When the battery is about to deplete, and the voltage drops to 3.0V, the protection circuit will shut down, preventing further discharge and providing over-discharge protection.
Over-Charge Protection: During battery charging, when the voltage reaches the maximum battery voltage (4.2V), the protection circuit will automatically cut off power, indicating that the battery is fully charged and providing over-charge protection.
Short Circuit Protection: In the event of a short circuit, the protection circuit will automatically shut down within milliseconds and will not power on again. Note that if the battery is short-circuited (bypassing the protection circuit), the protection circuit may also fail due to prolonged high current or component overheating.
Storage & Usage: During long-term storage, keep the battery charged between 40% and 60%. We recommend charging the battery once every 3 months after receiving it, maintaining a voltage of 3.7-4.0V. Store the battery in a cool, dry place.
