Top 10 Best Esp32 Battery

Please note battery overcurrent protection is not a panacea, please do not continue to charge and discharge with large current, or the current and voltage beyond the range, otherwise the protection board will be damaged and invalid. When using for the first time, please charge and activate the protection board first. 1100mAh The recommended battery charging current is 0.2A, with a maximum of 1A. The recommended discharge current is 0.5A, the maximum is not more than 1A, the protection board is equipped with mos tube, the overcurrent protection instantaneous is 1.6-2.2A, and the charging voltage setting is recommended to be 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 overshoot 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.
