Rail (750Wh) Spare battery for Rail 9.8XT

[Tmack1960]

Hi - Would anyone know if you can purchase one of the smaller capacity Bosch Powertubes as a spare assuming there is some kind of adapter that would allow it to fit in the downtube?
Thanks

I have been told you can, Bosch smart system has a 500wh and 625wh compatible batteries. May pay to ask Trek if there is a spacer or similar?

I’m not sure if there’s a piggyback system you can use but I have used my 500wh PF battery in my Rail 9.7 (2020)with no issues. Just make sure the locking system fit is secure. The LBS or Trek can help you out here. No adapter was needed for this method …for me.
