MakerFocus 4pcs 3.7V 3000mAh Lithium Rechargeable Battery 1S 1C Lipo Battery with Protection Board Insulated Rubber Tape and Micro JST 1.25 Plug for Ar duino NodeMCU ESP32 Development Board
Asin: B08T6GT7DV
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.
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.
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, Forms Overchargse Protection.
3000Mah: The Recommended Charging Current Is 0.6A, The Maximum Does Not Exceed 3A. The Discharge Current Is Recommended 1.5A, And The Maximum Does Not Exceed 3A.
Features
- Note: The battery overcurrent protection is not a panacea, do not continue to charge and discharge the current and voltage with a large current beyond the range, otherwise the protection board will be damaged and invalid
- 3000mAh: The recommended charging current is 0.6A, the maximum does not exceed 3A. The discharge current is recommended 1.5A, and the maximum does not exceed 3A
- 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, forms overchargse 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
