The Witty Fox 400mAh 3.7V Rechargeable Lithium Polymer Battery is a compact and reliable power source designed for a wide range of portable electronic projects and devices. With a nominal voltage of 3.7V and a capacity of 400mAh, this single-cell (1S) LiPo battery is ideal for lightweight applications such as DIY electronics, wearables, RC toys, and embedded systems.
It is engineered to deliver consistent performance across its 500-cycle lifespan, making it a dependable choice for long-term use. Additionally, it operates efficiently within a temperature range of 0°C to 50°C, ensuring stable output even in moderate environmental conditions.
To clarify a common question: the 400mAh capacity indicates that the battery can supply 0.4 amps of current for one hour. If you were to draw 1 amp, the battery would last approximately 24 minutes (0.4Ah ÷ 1A), not 400 hours.
This often gets confused with larger battery ratings like 400Ah (ampere-hours), which are typically used in automotive or solar power applications and can theoretically provide 1 amp for 400 hours. The Witty Fox 400mAh battery, however, is built for small electronics where compact size and rechargeable functionality are crucial.
