I purchased the '9kw EV Controller' for over 300 GBP, but it lacked a picture on the website. What I received was a standard 2.2kw Chinese controller that can be bought on eBay for 100 euros. It appeared dusty and old, contrary to the claim of being 'custom made.' The BMS I ordered was out of stock, which I learned after two months. I was told delivery would take three weeks, but it took ten. Documentation was unavailable, and after asking multiple times about the hall sensor pinout, I received no response. At least I got a refund, but I can’t give more than 1 star. Beware! A better alternative for the controller is kellycontrollers.
