The Benno Boost (Bosch smart system) runs the Bosch Smart System (BES3), a Bosch drive whose battery is proprietary to the system, so the replacement pack is one of its own, most often the Bosch PowerPack 545 (smart system) (545 Wh, 36 V, BES3), charged through the Bosch smart-system round charge port.
The Bosch smart system (BES3) shares nothing with the older eBike System 2: a BES2 PowerPack or PowerTube will not run this bike even where the pack looks identical, so confirm the smart-system display and the printed battery model number.
