It sounds like you’re having quite the challenge with your Bird ES100 scooter and those replacement controllers. When the voltage drops from 29V to 2.9V, it could be due to a wiring issue, a short circuit, or possibly a compatibility problem with the controllers you’re using. Sometimes, the cheapest parts might not be fully compatible, or they could be faulty.
If you’ve checked the wiring and everything seems right, it might be worth looking into a better-quality controller that’s more suited for your specific model. Testing the controllers on a different setup could also help determine if they are the source of the issue.
For situations like this, it’s similar to businesses needing tailored solutions. Investing in custom enterprise software development ensures compatibility, reliability, and smooth operation, just like getting the right controller would do for your scooter!
