The 72 Odyssey will require you to possess a 72V suitable controller, as well as a 72V charger. The stock Sur-Ron controller and charger aren't compatible. Should you’re trying to find a battery which is suitable along with your inventory Sur-Ron controller/charger, we recommend testing our 60V or 66V choices. https://troyyofrz.popup-blog.com/37102813/getting-my-surron-battery-to-work
