Will it hurt the battery if I keep the S1 Pro always plugged in?
No, you won't hurt the battery if you keep the S1 Pro always plugged in. Bose anticipated this use-case when it engineered the S1 Pro system.
The S1 Pro trickle-charges the battery when the S1 Pro is connected to AC power regardless of the position of the power switch. This works with the circuitry in the battery to keep the battery charged without harming it.
