For EVs it's possible to make something far
better, with proper motor current control, battery voltage & current monitoring, controller & motor temp sensing, etc, etc. But any new product on the market unfortunately has to compete with the existing controllers that are already being mass manufactured (possibly for a different application) and are consequently cheap. The usual story for any new product, of course!
But it certainly bugs me that these controllers are the 'default'. Any time I see someone talking about rough starts, or cooking a motor or controller, or other weirdnesses, it really gets my goat, because it is quite simple to NOT have these problems exist at all, for hardly any additional expense in the controller. Any yet these things give such a bad first impression, and really make the whole EV area look amateur.
