UPGRADE: 200 amps Controller. Stealth Bomber Enduro Ebike 12000w QS273 5T Motor

#ebike #enduroebike #stealthbomber Please Subscribe! I upgraded my Sabvoton 150 amps (SVMC072150) controller for a 200 amps (SVMC072200). The peak watts remain the same (12600w) because of the 150 amps BMS of the battery but the torque and acceleretation are increase considerably. Front wheel lift unwantedly even if I weight 245lbs + the bike 172lbs and about 15 lbs of gear I wear. About 430lbs total. Acceleration test: 0 to 51.4 km/h (32mph) in 3 seconds. For the sabvoton controller set up, I reduced to 1/3 the amps on the first half of the throttle. First because it was too powerful when I bring my bike upstairs on my ramps and to be able to make slow start without wheeleing all the time. 😃 I set the e-brake to 60 amps which provide about 80-85% of all the braking and 15-20% is the hydraulic sustem. The flux weakening is set to 50 amps. The flux weakening of 2 of my 3 sabvoton controllers are locked at 50 amps. I think it's because more than 50, it overheat the controller and could burn it. I'm not sure about that but in the manuel it says it creating a lot of heat and they recommand 50 amps. I entered the proper poles pairs number for this specific motor that is 16 pairs. 32 poles total. Other than that on this bike it's about all the changes I made. The motorcycle rims are 1.85" wide. The tires are motorcycle tires 80/100-19" 80mm wide, 100mm high and 19" circonference. Disc brakes are 203mm. The motor is a 5T with less top speed and more acceleration at the start compared to a 3T for exemple. Still the top speed I got was 75 km/h (47mph)
