The Specialized Turbo Como 4.0 (Brose) runs the Brose Drive / Specialized Turbo (Full Power), a Brose drive whose battery is proprietary to the system, so the replacement pack is one of its own, most often the Specialized M3-700 (700 Wh, 42 V charge, Rosenberger), charged through the Rosenberger / Magcode magnetic charge connector.
A Bosch or Shimano battery will never fit a Specialized full-power bike: the pack, the Rosenberger magnetic port and the 42 V charger are all Specialized-specific, and the lightweight SL range uses a different, smaller pack again.
