I dont trust my e-wheels to fully balance either. Im not saying it doesnt, Im just not saying I trust it. I do like it for most charging tho. Its nice to be able to set the amperage. I have used the lesser charge modes (80%) before, when I planned on not riding for a few weeks. Every now and then I break out the stock chargers and let them sit for a while... 1 Quote Link to comment Share on other sites More sharing options...

Do you have any reason/intuition for that? Because the charger doesn't balance anything. The battery pack does it. And the end of the charging process is the same for any charger, as the current goes towards zero then. Right? 1 Quote Link to comment Share on other sites More sharing options...

Because, when the charge voltage hits 84V, and as soon as it hits 84V (measurement accuracy notwithstanding!), it simply turns off. It doesn't idle at 84V like the stock charger does. Is it top balanced? Perhaps, but I don't think the accuracy is good to the 1/10th of a volt at that range. 2 Quote Link to comment Share on other sites More sharing options...

Well then the case is clear. How can ewheels sell something like this? They should know better. - Maxbe an extra stock charger would be better then? The 16X has two charge ports.

If I can figure out how to get a charge control graph out of EUCWorld, I'll verify with data... right now, it's one of those "why did it just turn off... it should have taken longer than that" not-good-feelings.

No1up Posted May 22, 2022 Author Share Posted May 22, 2022 I like the fast charger. The ability to set it to 80% for storage is great. Speed things up if I need or slow it down if not in a hurry. If I’m home and not in a hurry I can use the stock one. 1 Quote Link to comment Share on other sites More sharing options...

The stock one is 1.5 amps which was painfully slow. I have an 84.4 Ewheels charger that I use with my v10f, V11 and 16x (using different adapters). Mine can do 6 amps but only do 4 amps on the 16x.

My ewheels charger goes to 84.4 every time. I had experienced that my 100v ewheels gotway charger seemed to only go to 98 volts. But when I tested it again yesterday it went all the way to 100.8. IDK. I have a slight suspicion that when I flip between different charge rates and battery % on the ewheels charger it gets confused. - I think thats what happened before but it's just a guess.

I refuse to buy a begode wheel and I love the lights on the 16x To me that would be like playing Russian roulette, with only one or two empty chambers... It was originally a 25 mph wheel. But then GotWay released the Nikola at the same time. It seems that to compete, KingSong swapped their 2000W motor with a 2200W and advertised the same top speed, without optimizing or testing enough. The result was quite a few faceplants over 25 mph.

Not that I've ever had a cutout on my 16X (which is really a 16XS controller with double the battery—16XSLR?), but KS seems to be very/overly aggressive about protecting the electronics from overburden and subsequent failure. When you're above 25 mph, you really are near the knife's edge and bumps and slight balance correction leans can and will take you to a place where the knife will cut power. Given the 16X's 6P configuration, there really isn't a solid reason why they cut it off so eagerly. But they do, and if you go there very often, you will lose. 1 Quote Link to comment Share on other sites More sharing options...

Jason at ewheels said it should handle 28mph no problem Theres a thread around here about it somewhere. It has something to do with the rpm of the rim and the frequency of the motor, iirc. It cant handle 28mph PERIOD, as max is more like 27mph. The 31mph they claim is wildly overstated. I think most owners are reporting that 25mph (22mph actual) is much safer. If you want to ride the wheel in excess of 20mph, you should be aware that it doesnt have as much headroom as the 18xl does. In contrast, the 18xl has been KNOWN to handle its top speed of 27mph and still have headroom to spare. KS wheels once had the reputation of being a little conservative AND building dependable wheels. The 16x and 18xl are the last of those to follow this ideology. If you are already pondering top speed ability of wheels at 27mph, you may want to look towards something faster. The 16x is a great wheel, but speed is NOT its forte. I think the 16x shines in lower speed and torque, where the 18xl shines in comfort and reliability nearer its top speeds. I feel that some people are putting too much faith in tiltbacks and beeps. The KS tiltback IS a great feature, but its not a great idea to rely on it. I view tiltbacks as a stern warning that you have ALREADY screwed up. Tiltbacks and warning do NOT read the future. They also arent capable of knowing what you are going to ask of the wheel in a moments notice. If you are relying on the wheel to save you from yourself, while knowingly pushing its limits... YOU will be learning quickly the difference between riding smartly and expecting some inaccurate battery readings to save you. Riding smartly becomes even MORE important if you ride among cars/people or dont suit up like a soldier going to war. Knowing limitations and respecting them, while using your brain, is a much better solution than beeps/tiltback and plastic body armor. Of course, this only applies when you know the TRUTH about what to expect and don't blindly listen to the hype a manufacturer tells you. Lets not forget, the wheels dont know how heavy you are either. A tiltback on my `125lb ass, leaves more safety room than a tiltback for a 200lbs person. If you want to ride 20mph, you need a 30mph wheel (if you're heavy). If you want to cruise at 30mph, you need a 40+mph wheel. Anyone wanting to ride 40+mph, needs definitely look to the 50mph wheels. Of course, safety and headroom declines as battery level drops. It also declines as battery health ages. Cold weather is also a big factor...

Tiltback is actually the wheel racing ahead to get in front of your center of gravity and it can only happen when the motor has enough additional power to get itself ahead of you. When you are already near max power that little acceleration to initiate tiltback might actually be enough to overpower the wheel and result in an overpower cutout. Tiltback seems to be based solely on the speedometer and not on operational power demand, so it's kind of a not so good safety mechanism (see the PWM based reset-the-tiltback-speed effort). What seems to be happening with the 16X is that yes, it'll let you go 30 mph and it might (it doesn't) have enough power to tilt you back if the speedometer sees 31. BUT, at that speed it doesn't have enough power for anything else. No bumps. No micro shifting your weight forward. No potholes. No gusts of wind. No slight hills. No acceleration. I haven't the courage to try to see how fast it'll go downhill, when 'forward' power isn't in high demand... you might be ok. But you might need extensive physical therapy too. This is definitely a case of "take the community's word for it". Edited May 26, 2022 by Tawpie 1 Quote Link to comment Share on other sites More sharing options...
Funky Posted May 26, 2022 Share Posted May 26, 2022 Off topic.. But what would the "real" max speed for 18xl be then? also 27mph? As i'm riding 22-25mph nowadays.. And i'm much heavier 280lbs. Wanted to know if i'm not riding at my wheels limit.. Doh i never have felt tilt back. As i always slow down, when i hear my speed alarm at 25mph.

I would listen to these guys and keep it below 26. Since reading this thread I have changed how I ride my 16x. I now don't go above 26mph. I was visiting 30mph before. I think the only thing that saved me was that I never rode it below 70% I'm 6'8" 225 without gear. I absolutely think you can ride 16xs and 18xls and "get away with it" I did for quite some time. The problem is that us big guys go from being fine to cutout way faster than smaller guys. Let's say I'm cruising at 26mph slightly up hill, and a gust of wind come up. No big deal if I'm a foot shorter and 40lbs lighter, but that gust put me on the razors edge and I don't even know it. Then I adjust my weight or hit a small bump and boom I'm down, where the lighter rider stays up. I now keep it 22mph and lower on slight up hills and I no longer cross the trolley tracks at 27mph like I was before. What's deceiving g is the 16x really feels like it could do it. It has so much torque even at thebtop of its range, that you just can't even feel the wheel straining. 1 Quote Link to comment Share on other sites More sharing options...

I don’t tend to ride at that speed sustained. My actual avg speed is like 16min lol. But on clean straights I push a little. I was debating an EXN but the Master just looks so good… it the EXN is proven, idk 😭 I’d get the hero from alien rides but it runs the LG50 battery pack.
