The 52V 20Ah Hard Case Triangular eBike Battery is a high capacity and designed to fit securely within your frame. They often fit frames that won’t easily take a standard downtube battery.

The battery contains a BMS (Battery Management System) that shuts down the battery when it becomes discharged. It also protects the battery from overload and accidental short circuit. It also monitors each cell during charge to ensure uniform charging of all cells, which helps to prolong the batteries’ life.

Please check the sizing photo in the gallery.

They are suitable for the BBSHD – at 52V we do NOT recommend for the BBS02b. If you want a triangular battery for your BBS02b – get this 48V version instead.
