Good to know

The wire leads are not pre-terminated with a connector, giving you full control over the connection method. Always observe correct polarity (red = positive, black = negative) and use a charger designed for 3.7 V Li-Po cells with a 4.2 V charge limit. For best longevity, store the battery at 3.7–3.8 V per cell in a cool, dry place.
