Because of 4QD’s designs, most of our controllers can be made in 48v versions. This generally involves upgrading several components to higher voltage devices and the use or higher voltage MOSFETs and capacitors, as well Read More

What voltage should I use  – 12v, 24v, 36v or 48v? We are often asked whether 12v or 24v is best for a battery powered motor system [the short answer is 24v]. For a more Read More
