Rated current: 9A
Low voltage shutoff: 31.5v
Motor control: Pre-wired for simple on/off motor operation when plugged into our 36v throttle (see Related Products at bottom of page). Controller ship one week from time of purchase.

The part was easy to install

The 36V controller shipped is marked as 7A rated – 15A max with a 30V cutoff. The 36V controller online cites 9A rated – 18A max with a 31.5V cutoff. The lower amp ratings may be correct because I am upgrading an existing 24V motor I purchased from them several years ago. That aside, the controller works perfectly with the variable throttle and cuts out at precisely 30V.

Had a problem with my controller. They made it right.


Perfect for what I needed!
