High Power 48v-72v 3000W-5000w Electric Scooter Ebike 80A Sabvoton Controller

Product Information

Field weakening. I believe it's settable from 0-100A. I need to do some more testing on how much it effects my top speed but I think I saw 53mph with it set to 50A, but I can't remember for sure so I'll have to go test again after I recharge the battery. Nice thing with field weakening is that it only decreases the efficiency when it's in use, which is usually only when you make those short high speed sprints, not at normal cruising speed. Sabvoton controller only design sine wave type controller so far, it’s brushless DC controller, 120 degree phase angle. Generally, we matched it well with QS Motor, if you want to match with new brand motor, some parameters should be tested by yourself. for my maguara twist throttle, I was told to set the TPS dead low to 5% .....because at a higher setting, the throttle would not send power to the motor until it had been turned 1/2" of twist....which I did not like it that way.[/quote] Sabvoton 72V 150A eBike Scooter Controller Stealth Bomber SVMC72150 V1 V2 Support Plug and Play Display The controller enjoys high efficiency due to space vector converter control algorithm which can effectively reduce the temperature rise of controller and extend battery life mileage

The new sabvotons need some air flow, otherwise you'll reach the temperature limit in about 30minutes of hard riding during the hot days of summer. On my machine, the controller was encased at the rear, with no air flow whatsoever, so I had to build a water cooling system. Well, in my opinion, at least between these two controllers, the Sabvoton is the clear winner. But my test was not at all imparial, the kelly is rated at 120V and was only running at 72V, so it is potentially way more powerful than the sabvoton. So in terms of pure power, I think the kelly would be the clear winner with the appropriate battery.Also maybe I d like to know, which model do you have, and if you have any other issues with Sabvoton ?

The motor torque ripple will be reduced to the minimum, so as toensure electric vehicle to run without any noise and vibration, smoothly, andcomfortably. I also tried a big 250A continuous Lingbo sinewave controller. It seemed far inferior to me than the sabvoton. Lots of throttle lag, weird regen, seemed somewhat less powerful or barely equivalent to a 150A sabvoton, seemed very inefficient in terms of power consumption, the programming software wasn't good.... So far the sabvoton remains my absolute favorite. Our products have won national invention patents and international certificates, and we are recognized in terms of quality and reputation. Phase current control based throttle - This makes riding very nice. It has a variable up/down time limit settable in milliseconds to help buffer out any throttle jolts that happen while riding. The throttle voltage end points are adjustable so it will match any pot type throttle or hall based throttle and provide full range. The throttle mid point and also the phase current mid points are adjustable so that you can customize the throttle curve. Connection to the controller is a bit easier on the Kelly, no need to select the right port, it is done automatically. The Kelly manual notice is stupid as shit, it mentions that you should absolutely remove all wiring from the controller and supply it with 10-30V to make any programming, while it is actually not necessary at all and works perfectly fine even when all the wires are connected to the machine. Completely moronic advice.Wish I could help you with the #30h error. I think others have reported that error before. Any good results?

If you don't want high top speeds, but you want high voltage, what are you doing? Every reduction gear stage robs you of several percent efficiency. For a mid drive it's most efficient with just 1 stage, chain to drive gear. If you don't need high speed, then you don't need high voltage, you need a motor that has the correct KV. For that matter if you did want high speed you could do it with low voltage, it would just require more amps. Amberwolf, some of those are good reasons, but they don't really apply to what this controller is designed for, medium power hub motors. System status and fault intelligent management system caneffectively monitor the current system operating mode external input state ,thecase of system failure, and the LED flashes at the same time to facilitate thediagnosis and maintenance.

Suitable Motor: 3000W, 4000W, 5000W, 6000W DC Brushless Motors.

I’ve been through 3 tft displays. I’m also using a Sabvoton controller. I find that they die when the battery voltage is cut while riding, i.e BMS low voltage cell protection, CB accidentally switched off, negative cable unplugged. I’ve tried repairing; found that Q1 and Q4 were dead plus a diode. Both transistors are rated for 100V. Must be more failed components than this as display is not fixed yet.

It's special design for QS brushless motor controller for Conversion Kits, which can match with QS HUB MOTOR Rated Power 3000W-4000w.if you want to match with new brand motor, some parameters should be tested by yourself. Sabvoton: Very smooth start, no vibration, no noise whasoever. Extremely easy to control, it feels like a gas powered engine. The total absence of noise is pretty much amazing. The start up torque from 0-20kmh feels a tiny bit lower than the Kelly, but passed this point the power and torque seem to go up more and more, until about 70km/h where it starts to hit the top of the curve. I reached 115kmh without the flux weakening enabled, in less time that what I needed to reach 97kmh with the Kelly. The regen was set up to 75A, and it feels pretty strong, works well. I really enjoyed the ride with this controller, The only thing I actually liked on the Kelly was the sound from 5-30km/h. To me the Sabvoton feeled far superior. So far, I tested all those controllers on a 72V 35Ah lead acid battery, on my electric motorbike, with 16 inches 3000W QS V3 high speed motor. Here are some pictures to get a good idea of it's physical size. It's very similar to a Xie Chang 24 FET, but it's much heavier and the quality of construction is vastly superior. It takes only 3 minutes for the motor to be well matched on its bestelectronic angle at the first time.

Sabvoton Controller 72200

I think I have TPS dead low 20, and TPS dead high 70. I understand these as limits for throttle, corresponding to 0-5V throttle output signal. Every throttle is a bit different, but real values are probably more like 1-4 V. So 1V corresponds to TPS dead low 20 (20%), and upper 4V as TPS dead high will be lets say 80 (80%). Thats how I understand it.[/quote] A: Delivery by Express will take 3-5 working days to reach your door. Delivery by sea will take 15-35 days to reach your port.
