48v 20ah e-bike battery

First run I went from steeled and Yonge and then rode around two days downtown doing errands before I needed to recharge . Guy who had the bike before me did some work to the battery not sure what but it holds a hell of a lot of juice. Priced to go, charger included want gone today or price goes up . Lock cylinder is gone as someone tried to steal it off my bike but functions perfectly .
