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 Arduino ESP32 Development Board
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 Arduino ESP32 Development Board
  • Charging Method: 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
  • 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 overcharge protection
  • 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
  • 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

MakerHawk 3.7V 3000mAh LiPo Battery Rechargeable 1S 3C 103665 Lithium Polymer Battery with Protection Board Insulated Rubber Tape, Micro JST 1.25 Plug for Arduino ESP32 Development Board (2 Pack)
MakerHawk 3.7V 3000mAh LiPo Battery Rechargeable 1S 3C 103665 Lithium Polymer Battery with Protection Board Insulated Rubber Tape, Micro JST 1.25 Plug for Arduino ESP32 Development Board (2 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.
