Add a 60v 20 AH Battery stepover or step thru

The only battery that fits the Step over frames can be mounted inside the frame using just double-sided tape. No drilling is necessary. The battery is displayed wrapped in a custom design.... Wraps can be designed in any style, battery is black
The price for the battery and black case is $550.00 only ; custom wrapping costs extra as well.
Can you find a battery that fits the frame any better?
