Frequently asked questions
How should I charge this battery?
Use a single-cell Li-Po charger with a 4.2 V charge limit, preferably a module with built-in protection. Never connect it directly to a 5 V supply.
Is it compatible with a 3.3 V microcontroller board?
Yes, as a source it can power 3.3 V boards through a suitable regulator or a board with a battery input designed for Li-Po cells. Its voltage ranges from about 3.0 V to 4.2 V, so check the board's input range.
