Witty Fox 3.7V 7000mAh Li-Ion Battery This is 3.7 volt lithium ion battery of 7000 mAh, the Li-ion battery is one of the most modern battery technologies available. Lithium ions are the primary element in its electrochemistry. Lithium can easily pass through a micro-permeable separator because of its extremely small size (third in size only to hydrogen and helium). Lithium ion batteries are therefore capable of having a very high voltage as well as high charge storage per unit of mass and volume. This is compatible with TP4056 Lithium Battery Charging Board This 3.7 volt 7000 mah lithium ion rechargeable batteries are widely used in GPS , DVD, Tablet PC, Development boards like arduino , BBC micro:bit , MP4 Player, Power Bank, Mobile Backup Power Supply, Electric toys , Bluetooth Speaker, IOT and Industrial applications. This 3.7V 7000 mAh Li-ion battery is from the brand Witty fox which is invented by TIF Labs. Witty fox is a range of cutting-edge products designed to make prototyping easier for you. A broad variety of items are available, including Li-Ion Batteries, Witty Fox ESP32 Storm Board with support for battery charging ,Witty Fox - ESP32 Storm Board with On-Board Li-ion Battery & Wireless Programming , Witty Fox ESP Programmer, Witty Fox S17021 humidity temperature sensor, and Witty Fox OPT3001 ambient light sensor.
