I have an e-bike motor with a system voltage of 36 V or 48 V. Isn’t that too much power for the 12V DC Cable?Updated 2 months ago

E-bike drive systems typically use 36 V or 48 V system voltage, depending on the manufacturer (in rare cases also other values such as 24 V or 52 V). However, this specification only refers to the internal voltage of the battery system and has no direct impact on the accessory or light output of your motor.

At these ports, the 36/48 V system voltage is never present. Instead, there is a regulated output voltage of 6 V or 12 V. This voltage is crucial for selecting the correct accessory cable.

To ensure your setup works reliably, please check the following in advance:

1. What output voltage does the accessory/light port of your motor provide?
   → 6 V or 12 V

2. Are any other consumers connected?
   → e.g. front/rear light on the same port

Depending on the output voltage, you can choose the appropriate cable:

Our cables feature integrated voltage conversion and work reliably with the SP Connect Charging Module and the Charging Anti Vibration Module. This regulates the e-bike’s input voltage to the charging voltage required for your smartphone – regardless of whether 6 V or 12 V is present at the motor.
