Rechargeable Lithium Battery Pack for Ar duino NodeMCU ESP32 Development Board

About this item

• Note: The battery overcurrent protection is not a panacea, please do not continue to charge and discharge high current, or the current and voltage beyond the range, otherwise the protection board will be damaged and invalid
• 2000mAh: The recommended charging current of the battery is 0.4A, the maximum does not exceed 2A. The recommended discharge current is 1A, and the maximum does not exceed 2A. This battery protection board is equipped with two mos tubes, overcurrent protection (instantaneous) 3.2A-5A, charging voltage setting recommended 4.2V
• Over-discharge protection: When the battery is about to run out and the voltage is as low as 3.0V, the protection board will also be turned off and can no longer be discharged, forming an over-discharge protection effect
• Overcharge protection: When charging the battery, when the voltage reaches the highest battery voltage (4.2V), the protection board will automatically power off and shut down, indicating that it will not continue to charge when fully charged, form an overcharge protection
• Short circuit protection: When an accidental short circuit occurs, the protection board will automatically shut down within a few milliseconds and will not be powered on again. Note that the cell is short-circuited (not through the protection board). The protection board will also fail due to continuous high current, or the components are heated and damaged
