YELUFT 3.7V 2000mAh LiPo Battery for ESP32, Meshtastic Node 4pcs

• Charging method: the recommended charging current of the battery is 0.4A, the maximum value is 2A. The recommended discharge current is 1A, and the maximum does not exceed 2A. This battery protection board is equipped with two Mos tubes, over current protection (undelayed) 3.2A-5A, recommended charging voltage setting 4.2V
• Protection against over-discharge: when the battery is almost empty and the voltage is only 3.0V, the protective board is also switched off and can no longer be discharged, creating over-discharge protection
• Protection against overcharging: when the battery is reached the highest battery voltage (4.2V) when charging the battery, the protective board will automatically shut off and turn off to indicate that the battery will not continue to charge when fully charged
• Short Circuit Protection: If an accidental short circuit occurs, the protection board will automatically shut down within a few milliseconds and will not turn on. Note that the cell is short-circuited (not by the protective board). The protective board fails even with sustained high current, or the components are heated and damaged
• Note: battery over-current protection is not a panacea, please do not continue to charge and discharge high currents, or current and voltage out of range, otherwise the protective board will be damaged and invalid
