Probably compatible

Seller explicitly lists 'Smart Step from 2019-2023' but the Smart Step is a 36 V system (EBR: 36V 10.4Ah, 36 V 15 A controller); a 48 V pack is a voltage mismatch with the stock controller unless a later Smart Step variant used 48 V. Not downgraded to incompatible because the seller states fit explicitly; needs confirmation.
