The maximum operating current of this battery is only about 1A, can not be used for unmanned aerial vehicles, model aircraft or power tools and other products that require high current. 2. This battery interface is JST 1.25 pitch male, it can be matched with some ESP32 Development Board that it come with Female JST 1.25 mm connectors. Specification: Standard Voltage: 3.7V Rated Capacity: 1000mAh Weight: About 17g Size: 44*26*9（mm） Working Current: 1.5A Overcurrent protection: 2~3A Overcharge limit pressure: 4.25±0.05V Over-voltage limit pressure: 2.45±0.30V Charge current time: Standard Charging: 0.2C (8 hours); Fast charging: 0.5C (2.5 hours) The maximum charging current: 0.5C Continuous Discharge Current: 0.5C The maximum discharge current: 1C End-off voltage: 2.75V/pcs Allowable charging temperature: 0℃ ~ +45 ℃ Allowable discharge temperature: -10 ~ +60 ℃ Allowable storage temperature: -10 ~ +40 ℃( within 3 months); -10 ~ +30 ℃ ( within 6 months) Standard Charging Method: Charging this battery to 4.25V at 0.2C constant current, then charge the battery at a constant voltage of 4.2V till it's charging current≤ 0.05C. 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.
