KT-15A E-Bike Controller - Universal Brushless Motor Controller For 36V/48V Electric Bicycles

About This Product

E-bike tinkerers and DIY builders, this KT-15A controller is exactly what you need to upgrade or repair your electric bicycle! Rated for 36V or 48V systems, this compact controller handles up to 15 amps maximum current, making it perfect for 250-350W brushless motors.

The metal and plastic construction dissipates heat well and feels durable, while the compact size makes installation in tight frames manageable. The 9-pin motor connector and 3-pin PAS plug are standard KT system connections, and it works with 1-4.2V speed settings.

What's really important to know is that this only works with KT displays - the communication protocol is proprietary, so make sure you've got matching components. The low voltage protection at 30V/40V prevents battery damage, and the build quality is noticeably better than some cheap generic controllers.

I've used these in several conversion projects, and they provide smooth, reliable power delivery without the jerky acceleration some controllers produce.

Whether you're building a custom e-bike from scratch, upgrading an existing system, or replacing a failed controller, this unit delivers consistent performance. Your motor will run more efficiently, acceleration will be smoother, and you'll have that reliable power delivery that makes e-biking so enjoyable. Just remember to double-check your compatibility and take your time with the wiring - the effort is worth it when you've got a perfectly functioning electric bicycle that rides exactly how you want it to!
