Charging & Safety Information
Use a dedicated single-cell Li-Po charging circuit designed for a 3.7V battery. Do not connect the battery directly to a 5V power supply.
Always observe the correct polarity when connecting the battery. Avoid short circuits, puncturing, crushing, bending, overcharging, deep discharge, or exposure to excessive heat.
Do not use a swollen, damaged, leaking, or physically deformed battery. If the battery becomes unusually hot during charging or operation, disconnect it and discontinue use.
Important: Do not assume that the battery includes a protection circuit. Confirm the specification of your particular battery variant before connecting it to a circuit.
