3,7V/500mAh Lipo Akku: 500507201

This RC battery accessory is defined by clear core data: 3.7 V voltage, 500 mAh capacity and LiPo battery chemistry for compatible Yairo applications. As a spare or replacement battery, it gives hobby users a straightforward way to match an existing setup against the stated electrical values instead of relying on broad category labels. The compact specification makes this battery relevant wherever the original setup calls for the same 3.7 V and 500 mAh combination. LiPo chemistry is widely used in RC systems where low weight and compact dimensions matter, and the stated values provide the practical reference point for checking fit within a compatible vehicle or accessory platform. The product data identifies this battery under the Yairo designation and places it within electric and battery car sets and accessories, which helps position it clearly as a power component rather than a complete vehicle. In day-to-day hobby use, a matching spare battery can support planned replacement cycles or extend bench preparation between running sessions when a compatible setup is already in service. The age marking in the data is 14 Years.
