Frequently asked questions
How should I charge this battery?
Use a charger designed for single-cell Li-Po or Li-ion batteries. The listing requires a specialized LiPo charger, so do not connect the cell directly to a generic power supply or to a 5V pin.
How do I power an ESP32 or Arduino with this cell?
Use a board or module with a built-in Li-Po charger and battery connector, or a regulator/boost converter matched to the 3.7V nominal voltage. Check the polarity before connecting, because reversed polarity can damage the cell and the circuit.
