This product is a connector adapter designed to allow compatibility between different RC battery plug types, specifically converting an EC5 battery connection to work with an XT90-equipped ESC or device. It features an XT90 female connector on one end and a male EC5 connector on the other, making it easy to bridge mismatched setups without soldering. The compact design, roughly a few inches long, keeps wiring clean while maintaining efficient power transfer. It is commonly used when upgrading electronics or mixing battery and ESC brands that use different connector standards. Designed for convenience, it provides a quick plug-and-play solution for RC cars, trucks, planes, and boats.
