Tool or Mower Battery (24-48v) (Bellevue EH7)

Hello, I'd like to repurpose an unwanted lawnmower or power tool battery to repair an electric scooter. If anyone has a working 24 volt, 36v or 48v one and it's charger, it would be put to good use. I have a bicycle so can't offer to take a lawnmower too, sorry. Some batteries can be a bit dangerous if they've been left uncharged for some time. So, I'm looking for one that has been used fairly recently. Many thanks.
