## Overview

The MakerFocus 4pcs 3.7V 1000mAh Lithium Polymer batteries come with a JST1.25 2-pin connector, designed specifically for ESP32 development boards and similar IoT devices. Featuring a robust protection board, these batteries prevent overcharge, over-discharge, and short circuits, ensuring safety and longevity. With a compact form factor and a recommended charging/discharging current of up to 1A, they deliver reliable, rechargeable power for your cutting-edge projects.

## Description

1. Charging Charging Current: the charging current shall not exceed 1A. 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 1A. 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 Limit Voltage: 4.2V Discharge Cut-off Voltage: 2.75V Standard Charge: 0.5C Standard Discharge: 0.5C Fast Charage: 1.0C Fast Discharage: 1.0C Charging Temperature: 0~+45℃ Discharging 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 Package Content: 4 x 3.7V 3.7Wh 1000mAh Lithium Polymer Batteries

Review: Working product, no issues - Appropriately sized, used two so far and no issues. Would be nice if the wires were a bit longer, but nothing a little solder and heat shrink can’t fix! Happy with my purchase
Review: Excellent IoT batteries - I purchased these for my Meshtastic builds. I am using them to power a variety of ESP32-S3 powered devices for Meshtastic. Nearly all are solar charged and with a small 2"x3" 60mw solar panel. The build quality has been excellent and on par with what I see from major hobby RC manufacturers. I have since purchased 3 more sets of different capacities for other projects.

## Features

- Charging Method: The recommended charging current is 0.5A, the maximum is not more than 1A. The discharge current is recommended 0.5A, and the maximum is not more than 1A
- 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
- 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

## 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.

### ⭐⭐⭐⭐⭐ Excellent IoT batteries

### ⭐⭐⭐⭐⭐ Appear to have the claimed
*by R***R on October 26, 2020*

I just ran all four of these through three full charge-discharge cycles and capacity is as claimed, with two of them even testing >1100mah. This was with a 0.5A charge and discharge current, and 3.0V LV cutoff on an iCharger 4010. Keep in mind these are not rated for any high current application and do have a small connector. Longevity remains to be seen but I am happy with them so far.
