How does a shunt-type regulator/rectifier differ from a series-type regulator/rectifier in its handling of excess stator output?

1. A shunt-type regulator converts AC to DC, while a series-type keeps the system running on AC
2. A shunt-type regulator is only compatible with lithium batteries, while a series-type is for lead-acid
3. A shunt-type regulator shorts excess stator current to ground, making the stator run hot, while a series-type opens the circuit to stop current flow
4. A shunt-type regulator disconnects the stator coils, while a series-type short-circuits them to ground
