Compared to SinTech or nucular 24f controllers, Bac8000 is definitely more powerful. We think it is a great controller choice as well, however it is not possible to realize it’s potential on the sur-ron factory motor. Thus, we can claim that all these 3 controllers are pretty much similar in terms of power output. That is why it is more important to compare the feedback and affordability of these controllers. With a trusted BAC controllers dealer there should not be any negative controller experience, however we often read negative reviews on BAC controllers technical support from our customers. SurRonshop works as a distributor of SinTech controller. We are responsible for technical support and warranty fix and our goal is to fully satisfy each SinTech controller customer. In case you have a controller failure and our technical specialist confirms it’s our fault, not only we offer a free repair, but also we cover delivery cost from you to us and backwards.
