AmpMax 3000W Controller (for BBSHD & BBS02B)

The AmpMax 3000W controller delivers substantial power, transforming the acceleration and top speed of both the BBSHD and BBS02B. It's compatible with battery voltages from 48V to 52V, providing flexibility in battery choice within this range. This controller pushes a maximum of 60A, offering a robust upgrade for off-road adventures, steep climbs, or achieving higher speeds on private property. While this current is highly effective, it's generally not recommended to exceed this limit for optimal motor longevity.

It often features both sine wave and square wave options, with sine wave providing smoother, quieter operation and square wave offering a potentially more aggressive power delivery. Many versions also include a "road legal" switch for limiting power on public roads. A significant benefit is its plug-and-play installation, directly replacing the stock Bafang controller, which simplifies the upgrade process for enthusiasts.

AmpMax 4000W Controller (for BBSHD & M615)

For those who seek even greater power and performance, the AmpMax line also offers the AmpMax 4000W controller. This high-performance controller is specifically designed for the Bafang BBSHD and M615 motors. It boasts an impressive peak maximum current of 90A, allowing for extreme power output. Due to this significantly higher current draw, it is crucial to pair the AmpMax 4000W controller with a suitable battery that can handle such demands without compromising performance or safety.

While the installation of any aftermarket controller requires some technical proficiency, the straightforward replacement process of AmpMax controllers, combined with the benefits in terms of raw power and enhanced ride dynamics, makes them highly worthwhile investments for maximizing your Bafang mid-drive motor's potential. They are excellent options for riders who want to push their e-bikes beyond typical street legal limits or demand the most aggressive and responsive performance from their setup.
