Compatibility answer

Will the Bosch 4A Charger (the smart system) work with the Bosch Performance Line CX Race Limited Edition drive unit (the smart system)?

Yes. Both use Bosch smart system charger (2A / 4A Charger).

Both records are reviewed against the manufacturers' sources; sources last checked 2026-10-14. Informational only: confirm with the manufacturer before buying.

Why

  • ✓ Both use Bosch smart system charger (2A / 4A Charger).

Good to know

  • Bosch lists the Compact, Standard and Fast Charger separately, under 'Battery chargers for the Bosch eBike system 2'; do not mix System 2 chargers with smart-system batteries or vice versa.
  • Chargers are region-specific: Bosch lists 220-240 V versions (Europe, Australia, South Africa, NZ) and 100-120 V versions (USA, Canada).
  • Bosch: chargers are IP40 and 'not for outdoor use'.
  • Bosch: 'Use only original Bosch batteries that the manufacturer has approved for your eBike' and 'Only charge the battery using original Bosch chargers'; Bosch warns other batteries/chargers can be a fire hazard (Bosch PowerTube 750 operating instructions, as hosted on ManualsLib).
  • Safety: use only batteries and chargers the drive-system maker approves. Lithium batteries that don't match can overheat.
