Good to know

This file does not yet list individual System 2 batteries (Bosch's System 2 product pages could not be read on 2026-10-13). Within System 2, frame vs rack vs PowerTube length/orientation still has to match the bike.
Bosch lists PowerTube variants 'in the smart system and in the Bosch eBike System 2' - same names, different systems.
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).
Not for smart-system batteries; the smart system uses the 2A/4A Charger.
Bosch footnote: 'Charging current is limited to 4A for the PowerPack 300 and Classic + Line batteries.'
