MakerFocus 4pcs 3.7V Lithium Rechargable Battery, 802540 3.7V 1000mAh Battery with Protection Board Insulated Rubber Tape Matched with ESP32 Development Board WIFI Kit for Arduino Nodemcu

Feature

[Note1]: After some customers reflected the reversed connectors, we have modified the connectors now, so all the new batteries are correct correct polarity now, you don't need to switch the polarity of the two wires. Thanks a ton for every customer's suggestion and support.
[Note2]: The maximum operating current of this battery is only about 1A, cannot be used for unmanned aerial vehicles, model aircraft or power tools and other products that require high current.
[Usage]: This product interface is 1.25 pitch male, it can be matched with ESP32 Development Board WIFI Kits for Arduino Nodemcu.
[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. Working Current: 1.5A
[Charge current time]: Standard Charging: 0.2C (8 hours); Fast charging: 0.5C (2.5 hours).
