Generally speaking, both VR and AR devices use lithium-ion or lithium-polymer batteries because they have the characteristics of high energy density, long lifespan and relatively light weight. VR devices typically use built-in batteries because a wireless, free and comfortable user experience is required in gaming and entertainment. This will lead to a shorter battery life and requires careful control of weight and heat. The battery capacities vary, but they are usually between 1,000mAh and 3,500mA.

AR devices are increasingly using external batteries to support longer usage times, especially in professional and industrial applications, where prolonged use and comfort are of the utmost importance. The external design offers greater flexibility, a larger battery capacity, and can reduce the heat inside the headset. The battery capacity ranges from 5,000mAh to 10,000mAh or higher.

The advantages of using Li-ion/Lipo batteries in VR/AR devices

● High energy density: Li-ion/Lipo batteries are compact in size and can store a large amount of energy, which is crucial for portable devices such as VR/AR devices.

● Light weight: These batteries are relatively light, which helps to enhance the overall comfort of the device.

● Compact size: Li-ion/Lipo batteries can be made in various shapes and sizes, making them highly suitable for the compact ergonomic design of VR/AR devices.

● Long cycle life: Li-ion/Lipo batteries can withstand a large number of charge and discharge cycles without significant capacity loss, thus ensuring long-term performance.

● High discharge rate: Li-ion/Lipo batteries can effectively provide large currents, meeting the demands of VR/AR devices with strict requirements for graphics and sensors.

● Fast charging: These types of batteries charge relatively quickly, making it convenient to charge them between uses.
