Re: 100+ Miles of Fun per Charge: 5.1kWh batt, 20kw capable

"So, with a few dollars worth of plastic you achieved the same effect as a 3000 dollar battery pack" Maybe thats where I got the idea you were making it sound easy... you left out the years of testing and datalogging on the way to getting some benefits. I never omitted the years of testing on purpo...

Re: 100+ Miles of Fun per Charge: 5.1kWh batt, 20kw capable

Let's put it that way: improving aero was my next step after boosting the battery capacity. I don't mind going 150 or 200 miles per charge and keep my mind open for anything that works. And brute force usually works! Thanks. And yeah, I agree, brute force always works, and if it doesn't its just be...

Re: 100+ Miles of Fun per Charge: 5.1kWh batt, 20kw capable

Aero shouldn't even be a concern for speeds between 20-25mph. You might be able to gain 10% range with a fairing but clearly this isn't a concern for most people as very few examples of fairings for e bikes exist. Obviously a trike will have much less drag compared to a bike because of the frontal ...

Re: new cyclone 3000 w mid-drive kit?

With good "battery management", hence why use a BMS... I thought the same way you did, until packs ruined, a 300 dollar mistake I don't plan on repeating. During my 3 years commuting on EVs to work I've seen plenty of 18S packs that display a clear 69 Volt reading in CA, especially so during cold mo...

Re: new cyclone 3000 w mid-drive kit?

I advice against parallel charging, use three or four 6S chargers to balance all the cells, every time. In my years of RC and EV experience, parallel charging is the fastest way to ruin your packs in demanding applications, been there, done that, and twice to be exact. After 8000 miles and three dam...

Re: 100+ Miles of Fun per Charge: 5.1kWh batt, 20kw capable

I've only mentioned trikes b/c I did the aero upgrades on a trike, the same way it could've been done on an upright MTB. Then you decided it was important to point the trikes can't do rocks or logs... who cares, that was not the point of my post, but you quickly jumped to compare aerodynamics with l...

Re: new cyclone 3000 w mid-drive kit?

Nice, SickBikeParts.com also carries the kit if you don't want to wait. 20S 6200 mAh should work well for shor range, depending on speed your Wh/mile will change drastically, @ 30mph average should be close to 45 Wh/mile on upright eBike. Dingus will tell you to stay away from Kelly controllers, whi...

Re: 100+ Miles of Fun per Charge: 5.1kWh batt, 20kw capable

Not the point of why I posted. Again, forget the trike... the point is that you could extend the range of that pack further with some aero tweaks that don't require enclosing your eBike inside a shell of any kind as Voltron seems to think... that's all. G. Well, thanks for compliments. But look. Thi...

We all have something we value more than something else in a design, but that doesn't make a different path wrong just because it...

Show me a single successful case of a faired off road bicycle or motocross bike and I'll believe it I guess. Everybody else seems to acknowledge trikes are good sometimes... Are you still unable to say a big battery is sometimes a reasonable thing when fairings aren't possible? Show you? what for? ...

gman1971 Dingus, for how long have you run 20S for? Any issues with the controller blowing up?

Interesting, once I've racked enough miles I'll see how accurate these # and calculators really are.

Re: 100+ Miles of Fun per Charge: 5.1kWh batt, 20kw capable

50+Wh/mile @ 35mph average while better than 60, is still a dismal number. I also cruise at 35 mph around here, except I do it at mid 20s Wh/mile with no pedaling and minimal cooling required. Also that means the batteries will also last a lot longer too, b/c you won't have to recharge them every da...

This is not a trikes vs bikes matter, this is an aero vs brute force discussion so lets keep things focused and inline with the thread of a 5.1kWh pack used to achieve long range. Here I've shown that good aero can also achieve the same results, and at two orders of magnitude less cost. The reason w...

Re: new cyclone 3000 w mid-drive kit?

Ran the trike A-1 on 20S today for the 1st time; I noticed a good 10% improvement in speed per gear, something expected since the pack is now 10% higher voltage than it was on 18S. The efficiency as in Wh/mile remains to be determined in the long run, but today it did the same mid 20s Wh/mile it did...
