Compatibility answer

Will the Bosch 4A Charger (the smart system) work with the Bosch Performance Line SX 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.
