About this item

• Note - The maximum working current of this 3.7v 2000mAh lipo battery is only about 1.5A, can not be used for unmanned aerial vehicles, model aircraft or power tools and other products that require high current
• Standard Charging Method - Charge this battery at 4.25V with a constant current of 0.2C, then charge the battery at a constant voltage of 4.2V up to the charging current≤0.05C.
• Application - This 1S 2000mAh lipo batteries can be used for esp32 arduino development board whose plug is 1.25mm
• Specifications - Material: Rechargeable Lithium Battery; Battery Voltage: 3.7V; Capacity: 2000mAh; Discharge: 1C; Plug: Micro JST 1.25
• Dimensions - 50 x 34 x 10 mm / 1.96 x 1.33 x 0.39 inches (L x W x H); Weight: 35 g

Safe and Reliable:

• Over-discharge protection: When the battery voltage drops to 3V, the protection board shuts off to prevent further discharge.
• Overcharge protection: During charging, once the voltage reaches 4.2V, the protection board automatically stops charging to prevent overcharging.
• Short-circuit protection: If an external short circuit occurs, the protection board shuts off within milliseconds. Note that if the battery itself shorts (bypassing the board), the high current or heat may damage the board.

Charging Method:

• Recommended charging current: 0.4A, max 2A.
• Recommended discharging current: 1A, max 2A.
• The protection board has overcurrent protection between 3.2A and 5A. Recommended charging voltage is 4.2V.

Note: Overcurrent protection isn't universal. Avoid charging or discharging at high currents or incorrect voltages, as this can damage the board. When using the battery for the first time, charge it to activate the protection board.
