Battery 3.7V

3.7v battery
a 3.7v battery is a rechargeable lithium-based battery commonly used in various electronic devices such as smartphones, wearable gadgets, iot devices, remote controls, and embedded systems. these batteries are lightweight, compact, and provide high energy density compared to traditional batteries.

the most common types of 3.7v batteries are lithium-ion (li-ion) and lithium polymer (li-po) batteries. li-ion batteries are cylindrical or rectangular and offer a stable voltage output, while li-po batteries are flexible, lightweight, and commonly used in drones and rc toys.
