Features

  • Charging Method: The recommended charging current is 0.6A, the maximum does not exceed 1.5A. The discharge current is recommended 0.6A, and the maximum does not exceed 1.5A
  • 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

    • Solid capacity and the JST connector fits perfectly for ESP32 projects
Size: 2
These 3000mAh LiPo batteries have worked well in several of my ESP32 and mesh networking projects. The JST 1.25 connector fits perfectly on the boards I use without needing an adapter. The capacity is as advertised and runtime on low-power IoT nodes has been solid. The protection board means I do not have to worry as much about over-discharge in the field. They come with the insulating tape already applied which is a nice touch. I have bought several packs now and quality has been consistent. ... show more

Used this to fix an old portable gaming device. Worked well, but a bit pricy for what you get.

    • They work
Size: 4
No complaints. They seem to work fine. I think the connector could be improved but that's not the battery's fault, that's an industry standard that needs to change.
