ESK433 is a High Power Stator Kit that consists of our high power stator for the Yamaha 660 Rhino with the high power regulator/rectifier that is a perfect match for it. This stator kit is all you need to increase total available output power to 400W, which roughly doubles the amount of power available for accessories on your Rhino. Our Stator is wound with the highest grade wire and the winding is optimized for maximum output. The Regulator/Rectifier is based on our high power circuitry and it has a dedicated output lead that is fused with an inline fuse and connects directly to the battery terminals. The great advantage of this setup is that the extra power is not running through the (undersized) stock wiring in the Rhino. Like all ElectroSport components this ESK433 High Power Stator Kit also comes with a full one year warranty.
