Compatibility answer

Will the Bosch PowerPack 400 Frame (the smart system) work with the Bosch Active Line drive unit (the smart system)?

Yes. Both use Bosch smart system PowerPack Frame (down-tube mounted) battery.

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 PowerPack Frame (down-tube mounted) battery.

Good to know

  • Bosch: 'All frame batteries of the smart system use the same mount' - you can insert another one 'provided the geometry of the eBike allows it'. Larger packs (725/800 Wh) are physically bigger, so frame clearance can rule them out.
  • Not interchangeable with Bosch eBike System 2 PowerPacks, even those with the same Wh number (e.g. PowerPack 400/500 System 2).
  • 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.
