Have no clue what a Premium or Premium XP is or does. Somebody makes that controller, and very likely they sell it under a variety of brand names.
There will be a HUGE number of controllers that will likely do the same job as your current controller, though, since you have not mentioned anything about what that is, can't really help you.
Ability to use two batteries, in series, is common to virtually all controllers. Everywhere.
Need to match voltage, amperage capacity, and connectivity to your motor, and compatibility with your motor type. You will need to know all of those things.
