Suitable for sensorless brushless motors. Key features and benefits - Clear compatibility: supports 2S Lipo or 6 cells NiMH packs, and 3S Lipo or 9 cells NiMH packs. Helps you match power and duration to your vehicle. - Flexible motor guidance: for 2S Lipo or NiMH, use 3670-size or smaller motors with KV less than 3000 for both on-road and off-road/buggy/monster applications. For 3S Lipo or NiMH, on-road still uses KV less than 3000, while off-road/buggy/monster uses KV less than 2500 with 3670-size or smaller motors. - Built-in protections: low voltage shutdown protection for lithium or nickel batteries, overheating protection, throttle signal protection, and engine blocking protection to enhance reliability and safety. What makes it stand out - Site-agnostic sizing guidance (3670-size or smaller) simplifies motor selection across different vehicle types. - Clear KV thresholds help you prevent over-stressing motors and preserve battery life. - Comprehensive protections reduce risk of damage during operation and setup. Practical scenarios - On-road RC car with 2S Lipo: pair a 3670-size or smaller motor with KV under 3000 for steady, controlled performance. - Off-road buggy with 2S Lipo or 6 NiMH: use a 3670-size or smaller motor with KV under 3000 to handle rough terrain while protecting components. - 3S Lipo setup: on-road use with a 3670-size or smaller motor KV under 3000; off-road/monster buggy use with KV under 2500 to manage higher demands and maintain motor protection.
