The Witty Fox 70mAh Rechargeable 3.7V Lithium Polymer Battery is a compact and lightweight power source designed for miniature electronics, wearable projects, and compact IoT devices. With a nominal voltage of 3.7V, this LiPo (Lithium Polymer) battery provides a reliable and efficient energy solution for low-power applications.
Its slim form factor makes it ideal for projects where space and weight are limited, while its 70mAh capacity offers sufficient power for intermittent or low-duty cycle operations. LiPo batteries like this one are known for their flat, pouch-like structure which allows more flexibility in design integration.
When fully charged, the output of a 3.7V LiPo battery can reach up to 4.2V, gradually dropping to 3.7V during regular usage. These batteries deliver high energy density and stable discharge rates, making them perfect for DIY electronics and hobbyist kits.
Though this specific battery offers 70mAh, LiPo batteries are available in various capacities — for example, a 500mAh battery would provide around 1.9 watt-hours (Wh) of energy. Always pair it with a proper charging circuit to ensure safety and longevity during use.
