The Seaview outfit took an early lead through a deflected Ross Clarke strike in the 12th minute to lead 1-0 at half-time.
Adam Lecky doubled that advantage shortly after the break with a looping effort over Ballymena goalkeeper Jordan Williamson.
Stephen Baxter’s men then started to run riot with Philip Lowry’s glancing header and a stunning strike from Paul Heatley in a frantic five-minute period putting the game well beyond Ballymena’s reach.
