## Description

1. Charging Charging Current: the charging current shall not exceed 0.55A. Charging with a higher current than the recommended value may cause problems with the charging and discharging performance, mechanical performance and safety performance of the battery cell, and may lead to heat generation or leakage Charging Voltage: the charging voltage shall not exceed 4.20V. 4.20V is the maximum limit of charging voltage, if the voltage is higher than the rated voltage value, it may cause problems of charging and discharging performance, mechanical performance and safety performance of the battery cell, and may lead to heat generation or leakage Prohibition of Reverse Charging: Connect the positive and negative terminals of the battery correctly, reverse charging is strictly prohibited. If the positive and negative terminals of the battery are reversed, it will not be possible to charge the battery cells. At the same time, reverse charging will reduce the charging and discharging performance and safety of the battery cell, and will lead to heat generation and leakage 2. Discharge The battery shall be discharged at less than 0.55A. High discharging current may reduce the discharging capacity significantly or cause over-heat It should be noted that the cell would be at over-discharged state by its self-discharge characteristics in case the cell is not used for long time. In order to prevent over-discharging, the cell shall be charged periodically to maintain between 3.7V and 3.9V. Over-discharging may causes loss of cell performance, characteristics, or battery functions 3. Parameters Nominal Voltage: 3.7V Charge Cut-off Voltage: 4.2V Discharge Cut-off voltage: 3.0V Standard Charge: 0.2C Standard Discharge: 0.2C Max Charage Rate: 0.5C Max Discharage Rate: 0.5C Charge Temperature: 0~45℃ Discharge Temperature: -20~60℃ 4. Note The lithium polymer battery should be stored in a cool, dry and well-ventilated place. And should be kept away from fire and high temperature Keep the storage capacity preferably at 30%-50% (at a voltage between 3.7- 3.9V) If the battery has been stored for more than six months or longer, the battery must be recharged Batteries should be stored within the above temperature and humidity ranges What You Will Get: 4 * 4.07Wh 1100mAh 3.7V Lithium Polymer Rechargeable Batteries

Review: Great for Xiao ESP32 - Using with the Xiao ESP32C3 which charges the battery when connected via usb and run on battery when disconnected. Literally leaves nothing else to do for power management.
Review: Good - So I charged one up with a cheap USB-to-jst lipo charger and then powered a 600ma 3-4v COB led bar with it. That led really hauls in the current and using a 4-led battery charge indicator designed for lipo/18650 batteries I watched it immediately drop from 4-bars to 2-bars and then hold there as the light shone. Those COB light bars generate tremendous heat though and with only the aluminum backing plate and no heatsink I had to shut it off within only 10-15 seconds. The battery recovered to 4-bars almost instantly. The upshot is the battery is more than capable of driving a 600ma load which I would say is a heavy load. The pigtail wires coming out of the battery are very fine, they’re pretty stiff and fully tinned iirc, and 1.25mm jst connectors are freaking tiny but I saw nothing to say it wouldn’t work fine under heavy load. When I got them the test battery was at 3.95v and it took some time to get it up to 4.2 and for the lipo charger to declare it done. I wasn’t paying attention when I ordered them and didn’t notice these are 1.25mm jst connectors, I was expecting 2mm. I’ve ordered 1.25mm pigtails but for now I put a 2mm pigtail on one for testing. I will probably replace all of the 1.25’s with 2’s but that’ll be on a case by case basis, the 1.25’s might be an advantage sometimes.

## Features

- 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 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
- Charging Method: Recommended charging current is 0.22A, with a maximum of 0.55A. Recommended discharge current is 0.22A, the maximum is no more than 0.55A, 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
- Note: 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
