That is a 21700 Lithium-ion rechargeable battery. These are the "big brothers" to the common 18650 cells, often used in high-power devices like electric vehicles (EVs), power tools, and high-end flashlights because they offer a better balance of energy density and power output Voltage (3.7V): This is the nominal voltage. When fully charged, it will sit at about 4.2V, and it’s considered "empty" around 2.5V to 3.0V
