On our scooter products, Solo, Egis & S-drive, the maximum current rating is shown on the product label, bordered by a square box. On an Egis controller, for example, the number in the square box will read '70' or '110', depending on whether the model is rated at 70A or 110A. The product label can be found on the metal 'base plate' of the controller and also contains other important information such as the product 'D' number, (our part number) and the serial number of that particular unit. The maximum current rating of our Pilot+ power module can also be found using the same method. For other products such as PG8, Pilot, VSI, VR2 etc. Synthesia Mac Key there.
