Michael Tucker Posted May 25, 2019 Share Posted May 25, 2019 I read on the Speed Reduction Graph thread that Different wheels, even between same manufacturer, use different voltages to report "percentage" of battery remaining. Chriull posted that KS18XL reports 0% at 3.0V and MSX reports 0% at 3.3V. If this is true, the "range test" may only be telling part of the story. Also in the Gotway Monster 2019 thread Jason says all his Gotway imports have a diode for charging protection, and some people on this forum have said that diode interferes with the battery pack's ability to charge or use the charge 100% (I'm not sure how the diode works). This diode may interfere with Garrie's use of voltmeter for range calculation too. 1 Quote Link to comment Share on other sites More sharing options...

Because when the wheel tilts-back and kicks you off the wheel when the battery is too low, you've ridden as far as the wheel can take you. Doesn't really matter how the wheel reports the percentages. When it stops, it stops. 1 Quote Link to comment Share on other sites More sharing options...
Popular Post mrelwood Posted May 25, 2019 Popular Post Share Posted May 25, 2019 (edited) 5 hours ago, eddiemoy said: Marty, I believe your latest video you did comparing it to the msv3+, you were only comparing it up to 57% left on msv3? Vs 68% o the 18XL. getting 11% difference, so assuming would be 20% if you run the battery down? ~14 miles difference. 70miles for 18XL and only high 50’s for msx/msv3? % doesn’t mean very much between manufacturers. Gotway’s 0% = KingSong’s 20%. And since the discharge curve is not linear, probably neither have even the 50% in the middle. Even the 100% is not the same. Add Gotway starting to beep at 15% (= KingSong 32%), and the KingSong speed reduction under 30%, multiplied by how easy the rider is annoyed by either feature, and you see that 440% of the perceived 10% range difference is up to personal misjudgement and lack of understanding the %. I would advise not to determine anything from having ridden the battery down to 68%. Edit: As Marty said, when the wheel stops, it stops, no matter the percentage, or even voltage. But I think even more important is how empty you are comfortable riding until it is no longer fun or meaningful. You are not going to plan your trips to end with careful crawling for the last 5 miles. Edited May 25, 2019 by mrelwood 3 1 Quote Link to comment Share on other sites More sharing options...

That's a big chunk of time and you're not having quite as much fun as you'd like because you are sticking to an identical route with nearly the same speeds. It's almost like a job The amount of time you invest to provide members with quantifiable data on each new wheel is simply remarkable! Hats off to your understanding wife as well. 5 Quote Link to comment Share on other sites More sharing options...

meepmeepmayer Posted May 25, 2019 Share Posted May 25, 2019 @eddiemoy @Marty Backe The 18(X)L discharges the cells down to 3.0V. All Gotways discharge only to 3.3V. So you get more range because the batteries are emptied further. That's the secret. I seem to recall a rumor GWwill do that from the Nikola, too, to stay competitive on range, but maybe I totally imagined that 0% on a Gotway (3.3V) is 25% on the 18XL (also 3.3V!). So in other words, the GW absolutely definitely already has stopped you from riding (heavy low battery tiltback) before the 18XL even starts any battery related speed reductions! I wrote about that here: https://forum.electricunicycle.org/topic/13209-speed-reduction-graph-rider-info-needed/?tab=comments#comment-234939 2 Quote Link to comment Share on other sites More sharing options...
