Yes, the RS80D has "current" limits, but an EV Warrior might be able to
generate a lot of torque before that limit is reached. The high torque
won't affect the speed controller, but it could cause a mechanical break
somewhere in the drive train.
A properly adjusted belt and pulley linkage protects the drive train,
motors and electrical system all in one simple and inexpensive package.
