3.7 V 2200 mAh LiPo Battery Rechargeable 1S 3C Lithium Polymer Battery with Protective Board Rubber Insulation Tape, Micro JST 1.25 Connector for Arduino ESP32 Development Board (Pack of 4)

Product description

• uses a brand new A-grade lithium cobalt oxide battery system, which not only provides higher energy and higher density compared to ternary system batteries, but also ensures more stable discharge performance and a longer service life. It also complies with UN 38.3 standards certification, ensuring safety and reliability.
• Over-discharge protection when the battery is about to discharge and the voltage drops to 3.0V, the protective circuit is activated to prevent further discharge and provide over-discharge protection.
• Overcharge protection during the battery charging process, when the voltage reaches the maximum battery voltage (4.2V), the protection circuit automatically turns off the power supply, indicating that the battery is fully charged and provides overcharge protection.
• Short circuit protection in case of short circuit, the protection circuit will automatically shut off within milliseconds and not turn on again. Please note that in the event of a short circuit of the battery (bypassing the protective circuit), the protective circuit may also fail due to persistent high currents or overheating of the components.
• Storage & Use During long-term storage, the battery should be charged between 40% and 60%. We recommend charging the battery once every 3 months after receipt and maintain a voltage of 3.7-4.0 V. Store the battery in a cool, dry place.
