I do not find this practice of using nonhomologated chargers sustainable. The chargers you’ve bought could get you into trouble. Even though the TC chargers are the same platform as what either Zero or DigiNow are using, they are not subject to the same QA standards and I’m not clear on how much anyone has programmed them for Zero operation independently.
Don't worry, rest assured there are people out there who have properly designed and tested TC-Charger based solutions for Zeros and other electric motorcyes that are up to European electrical and automotive standards. As of my experience yet, they have been more reliable and technically better protected against the elements than the Diginow V2. Couldn't compare it to V2.5 yet. I wonder how you can evaluate those solutions when you have never seen them or any data on it. I don't see how the Diginow solution is so 'special' when they can't even explain the 'magic' of their product.
