Great sinewave controller kit for my Laotie Ti30 !

I myself did over 1400 km on Boyueda and 1000 km on Laotian Ti30 - in both cases on factory square wave controllers - 45A JunLi in Boyueda and 37A JinPin in Laotie Ti30, respectively. In short, you should not use square wave controllers as we have in these devices at this power. I did a controller swap on my Laotian Ti30. The difference is colossal. No more jerking, switching 5 gears, etc. In standard controllers, the throttle response is based on the deflection angle (except for a huge dead scale) is as if assigned to a specific rotational speed of the engines, so with a small jump, a slight movement in a higher gear causes a mega jerk because the wheels want to change quickly speed. You know what I'm talking about. In sinusoidal controllers, the throttle acts as a gas pedal in the car, depending on the deflection, it doses the right amount of energy. As a result, it appears to be very flexible in all speed ranges. Of course, if we press harder, it will tear you forward. The power feels bigger from the bottom, the tires are literally screeching on the asphalt. I know that the energy losses in these controllers are smaller so we will gain on the range. The motors run very quietly. Acceleration is probably even greater than the standard ones. I saw the maximum speed of 85 km / h, so the same. But the driving experience is totally different. I am delighted :)
Minuses? Minimal perceptible lag on the throttle response, but probably the same as in Boyueda. This was not in Laotie Ti30. Less high speed regenerative braking force than Ti30 (same as Boyueda). The ECO mode was better for me in the Ti30, but maybe I got used to it. Besides, the same pluses, I feel like I have new, completely different equipment. I recommend - now driving is pure pleasure, really ...

ECO 27km / h, 1GEAR 35km / h, 2GEAR 55km / h, 3GEAR 85km / h
