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

Product Information

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. 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. I evaluated on contruction, pricing and feature set, ended up choosing this controller. I would really like to get this company or Adappto to use a power stage setup I've designed so I can start selling high power controllers. I have the gate drive/power stage figured out, but don't have my own controller brain and don't desire to design my own at this point. Amberwolf, some of those are good reasons, but they don't really apply to what this controller is designed for, medium power hub motors. I haven't tried it. Physically this controller is larger and should have a higher continuous wattage rating based on construction, but burst current wise both seem to be the same 12kW which means performance will be about the same for acceleration/wheelies etc, what most people want. Ebikes tend to be an easy load to drive because the motors are usually high inductance and only take high current bursts for a few seconds before they settle down to low current levels. You get more features with the Adappto, but that's reflected in the pricing. I have a customer who uses Cromotors as mid drives in a +3000lb vehicle so it's hard on controllers. They even managed to get one road legal by sustaining >20mph for over 1 mile. For commercial use I need a high quality controller than what the Xie Chang was providing and 8-12kw bursts make for a really fun bike.

is a electric bike, electric bicycle, electric scooter, electric motorcycle grade sine-wave motor controller, high efficiency, less noise and lower energy consumption, which makes your electric bike or electric motorcycle more comfortable and easier to control. Pros - cool features, affordable, high power, phase current control, protection, variable regen, virtually silent (my freewheel is much louder than the 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. The cover has been slightly changed, but the function haven't changed. Customers can buy them according to their needs.

Sabvoton Controller 72200

In terms of driving feeling, the Sabvoton is far superior because much smoother and has a very nice throttle feeling, without any lag. You have to understand here that those two controllers have a very different technology. Square wave for the Kelly and Sinewave for the sabvoton. Kelly is also doing square wave controllers, but I never have the opportunity to own one so far. If I’m successful with a repair I’ll provide details. Unfortunately I’m not able to attempt again until November. I use regen as a brake more than I care about recovered energy which is why I wanted variable regen. I have found that I consistently get much higher regen percentage using slip/slide charge mode, even if it's at a low setting. With it being variable you can coast or brake, best of both worlds. I'm going to trigger it to engage the 2nd throttle off of the ebrake switch in my Hydraulic Tektro brakes so all I need to do is lightly grab the front/rear brake lever and then twist a left hand throttle to vary how much I slow down. If I need hard braking, that's what the mechanical brakes do. System status and fault intelligent management system can effectively monitor the current system operating mode external input state ,the case of system failure, and the LED flashes at the same time to facilitate the diagnosis and maintenance.

Parameter modifications and settings are available through onlineconfiguration with online computer I'll only talk about the 72200 vs the 12401, since the 72150 is pretty much the same as the 72200, only with less power. Regen - It has 2 types of regen, slide regen and normal button regen activated by sending a +5v signal to the regen wire. Both as set in phse amps and can provide a strong regen force, enough to cause the rear 19x"3.0 Shinko SR244 tire to be on the verge of skidding while it's engaged at any speed over 20mph.

MQCON(Sabvoton)is a high-tech enterprise specializing in researching, developing, manufacturing and marketing the motor controller，here are some other types maybe workable for you. In my opinion, the only issue with the sabvoton is heat dissipation. At least for the new design. The old design doesn't heat nearly as much.About the low power wiring, they are pretty much the same, the indication markings on the Sabvoton are a bit clearer though (I had a hard time figuring out what was the ignition wire on the Kelly... it was a pink wire marked "PRW", I thought it was a red wire marked "B+" which would have been far more logical). 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. Full disclosure, I will be selling these units because I like them. I will start a separate thread in the appropriate for sale section, so please keep that discussion in that thread. Also maybe I d like to know, which model do you have, and if you have any other issues with Sabvoton ? [/quote] What number did you program into the TPS dead low setting of the Kelly controller parameter ? My throttle response on my Kelly 7218s was also poor, and I was told to change the TPS dead low setting to " 5" . I'm trying to find other Kelly users that want to work together and figure out what all these programmable paramaters mean and what is the best settings to input for them, for best overall performance of ones ebike setup. The Kelly manual isn't very understandable IMHO.[/quote]
