I'm searching a good quality control board for my converted lime segway scooter. I used the original board before but it fried a few days ago. So I'm searching for a control board which doesn't broke easily. Lime segway scooter model is sn1.0blk (300w nominal power, max speed 15mph, look like snsc1.0 but it had underlights). I want to use it with external battery and max speed 21kmh (I don't want to broke my scooter another time). So, does someone know where to buy a good quality control board for my scooter? thanks for any replies!
