Package Including:  4 * 1000mAh 852540 3.7V Lithium Rechargeable Battery

## Features

- 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
- 1000mAh: The recommended charging current is 0.2A, the maximum is not more than 1A. The discharge current is recommended 0.55A, and the maximum is not more than 3A
- 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 overcharge 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

## Questions & Answers

**Q: What are the dimensions of the pack?**
A: Dimensions(±2mm): 112 * 65 *8.8mm / 4.41 * 2.56 * 0.35inch(L*W*H)

**Q: is this compatible with rp2040 devices like the pico?**
A: Not 100% sure. I think you can use the battery and run the Pico on a breadboard, if that is what you were thinking. The RP runs off of 3.3Volts, so it is close enough. If you want to be safe you can use a TP4056. They are cheap enough.

**Q: Can this battery be safely charged with a TP4056?**
A: Hi, yes, it could be charged by TP4056.

**Q: Can I charge it with your charging board?**
A: Hi friend, you can use it can be matched with ESP32 Development Board WIFI Kits for Arduino Nodemcu, you could see the picture 4 on the listing.
