Probably compatible

Seller explicitly lists 'Smart Step from 2019-2023' but the Smart Step is a 36 V system (EBR: 36 V 10.4 Ah, 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.

Yose Power shop page: 48 V 17.5 Ah, 841 Wh, 'LG MJ1' cells, 1000+ cycles, approx 4.3 kg with holder; fits 'Sondors X XS MXS, Steps, Smart Step from 2019-2023, Smart Steps purchased from Costco for all years'. No UL 2271/2849 stated. The Smart Step is a 36 V bike according to Electric Bike Review, so a 48 V pack would be a change of voltage: confirm with the seller before ordering.
