Charging Charging Current: the charging current shall not exceed 1.5A. 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 1.5A. 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 Minimal Capacity: 3000mAh@0.2C Discharge Typical Capacity: 3050mAh@0.2C Discharge Standard Charge Method: Charging the battery initially with constant current at 0.2C and then with constant voltage at 4.2V till charge current declines to 0.02C Max Charage Rate: 0.5C Max Discharage Rate: 0.5C Charge Temperature: 0~15℃, Max 0.2C, Cut-off Voltage 4.1V; 15~45℃, Max 0.5C Cut-off Voltage 4.2V Discharge Temperature: -10~60℃ 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 * 11.1Wh 3000mAh 3.7V Lithium Polymer Rechargeable Batteries Review: Would buy again - Well made quality battery. Slim design allows for more milliamps in projects Review: Better than the energy bunny - Perfect battery for my project. Definitely will be getting more as needed ## Features - Charging Method: The recommended charging current is 0.6A, the maximum does not exceed 1.5A. The discharge current is recommended 0.6A, and the maximum does not exceed 1.5A - 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, forms 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 - Widely Application: With JST 1.25 plug, these lithium polymer batteries can be used for development board whose plug is SH1.25-2, such as ESP32 LoRa V3, ESP32 LoRa V4, Wireless Tracker, Mesh Node T114, Mesh Node T096 and electronic devices - 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 ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B08T6GT7DV | | Amperage | 1.5 Amps | | Antenna Location | ESP32 Development Board Whose Plug is SH1.25-2, Electronic Devices, Meshtastic Devices | | Battery Capacity | 3000 Milliamp Hours | | Battery Cell Type | Lithium Polymer | | Battery Weight | 185 Grams | | Battery capacity | 3000 Milliamp Hours | | Battery cell composition | Lithium Polymer | | Best Sellers Rank | #74,534 in Electronics ( See Top 100 in Electronics ) #544 in Rechargeable Household Batteries | | Brand | MakerFocus | | Customer Reviews | 4.6 out of 5 stars 262 Reviews | | Item Weight | 180 Grams | | Manufacturer | MakerFocus | | Model Name | 3665-1-3000-1S | | Model Number | 3665-1-3000-1S | | Number of Batteries | 4 Lithium Polymer batteries required. | | Number of batteries | 4 Lithium Polymer batteries required. | | Recommended uses for product | ESP32 Development Board Whose Plug is SH1.25-2, Electronic Devices, Meshtastic Devices | | Reusability | Rechargeable | | Voltage | 3.7 Volts | ## Product Details - **Battery capacity:** 3000 Milliamp Hours - **Battery cell composition:** Lithium Polymer - **Brand:** MakerFocus - **Number of batteries:** 4 Lithium Polymer batteries required. - **Recommended uses for product:** ESP32 Development Board Whose Plug is SH1.25-2, Electronic Devices, Mesh Node T114 ## Images ![3.7V 3000mAh Lithium Polymer Rechargeable Battery for ESP32 4pcs | 1S LiPo Battery, JST 1.25 Plug, Built-in Protection Board for Meshtastic Devices, ESP32 Development Board, Electronic Devices - Image 1](https://m.media-amazon.com/images/I/71Nulac2HvL.jpg) ![3.7V 3000mAh Lithium Polymer Rechargeable Battery for ESP32 4pcs | 1S LiPo Battery, JST 1.25 Plug, Built-in Protection Board for Meshtastic Devices, ESP32 Development Board, Electronic Devices - Image 2](https://m.media-amazon.com/images/I/71YDbR7AhjL.jpg) ![3.7V 3000mAh Lithium Polymer Rechargeable Battery for ESP32 4pcs | 1S LiPo Battery, JST 1.25 Plug, Built-in Protection Board for Meshtastic Devices, ESP32 Development Board, Electronic Devices - Image 3](https://m.media-amazon.com/images/I/71IfbHwRogL.jpg) ![3.7V 3000mAh Lithium Polymer Rechargeable Battery for ESP32 4pcs | 1S LiPo Battery, JST 1.25 Plug, Built-in Protection Board for Meshtastic Devices, ESP32 Development Board, Electronic Devices - Image 4](https://m.media-amazon.com/images/I/71-Oz+GIgLL.jpg) ![3.7V 3000mAh Lithium Polymer Rechargeable Battery for ESP32 4pcs | 1S LiPo Battery, JST 1.25 Plug, Built-in Protection Board for Meshtastic Devices, ESP32 Development Board, Electronic Devices - Image 5](https://m.media-amazon.com/images/I/71WC9oT8daL.jpg) ## 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. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Would buy again *by T***R on 15 March 2026* Well made quality battery.
