Super73 e-Bikes require their original battery be connected to the controller in order to add a secondary (after market) battery to your setup. POWERFUL LITHIUM has developed a cable that quickly and easily allows you to add a second battery (after market battery) with XT90 connector to your Super73 RX, R, S2 or ZX to extend your range.
Tip: Before selecting the Super73 cable option, make sure to identify the type of connector on your controller.
- Silver connector: Select the 'ZX' option.
- Black connector: Select the 'R, RX, S2' option.
Note: Both your stock Super73 battery and your secondary battery (after market battery) must be completely charged to full before connecting them to your bike for the first time.
