The 3 Packs EC5 to TRX Adapter set allows you to use EC5-equipped LiPo batteries with Traxxas vehicles that rely on TRX connectors on the ESC side, without modifying battery or ESC wiring.
EC5 connectors are commonly found on higher-capacity LiPo batteries, while Traxxas models use the proprietary TRX plug for factory ESC compatibility. These adapters provide a clean and reversible solution, making it easy to match EC5 batteries to TRX-based power systems.
Each adapter features an EC5 male input on the battery side and a TRX female output on the ESC side. Installation is quick and tool-free—simply plug in the adapter and drive, with no soldering or permanent wiring changes required.
