This is a high-quality, efficient brushless electronic speed control with an integrated switch-mode BEC. It can operate without the need for a separate receiver battery to power your servos and receivers, reducing weight and complexity. The GECKO series also includes ESC OPTO for giant flying. This series of ESCs also features an exposed, finned heat sink aluminum case with lightweight plastic end caps. Additional features include safe power arming along with an advanced programmable data logging system, low voltage cutoff, braking, timing, throttle input range, and more, making this series truly exceptional. In line with the developments of electronics research and the popular demand of the market, our BEC has been specially designed for extreme aerobatics and therefore can support high current applications, eliminating the possibility of unwanted shutdowns. It is also capable of supporting continuous simultaneous multiple servo operations typically found in CCPM equipped hardcore 3D E-helicopters.

No connectors and battery leads WAY too short

I use ZTW ESCs quite a bit and they work great. Well built and function as designed. They are a very good value. However, this is the first 45Amp ESC I have used. It came with no connectors at all. Not included or soldered onto any of the leads. Also, and more troublesome is that the battery leads are only 2.5 inches long. How could anyone ever use that?
