Re: Would a wind powered car work?

Thats what I expected. I guess it would only work if the pinwheel generators were on while the car was not on, then could be retracted... but then there is solar power. So I guess it doesnt matter.

Would a wind powered car work?

I drew up a design for an electric vehicle(in this case, it was a car, as I have the most experience with those) that would run on air. I drew a picture of it, and tested out some of the math required, but I was wondering if it could work, and if anyone here has tried. Basically, It looks like any n...

Re: Concerns with BMSBattery's Security

That is usually something you shouldn’t worry about. A lot of websites, forums, etc do this. Unless it was emailed by an actual person, I wouldn’t worry about it. Most likely it is automated

Re: I may be building an electric go-kart

So I found this 8Ah 2S1P lipo from hobbyking. https://hobbyking.com/en_us/zippy-flightmax-8000mah-2s1p-30c.html?___store=en_us I would need 12 of them. They are $34 each, and rated at 30c. The only thing I am wondering is would 2 of them working together be able to put out 500A, or would I need a ba...

Re: I may be building an electric go-kart

EDIT: I just realized the original ones I had would work because it contains six 40Ah batteries... 3C on 240Ah That only works if you parallel the 40Ah batteries. What voltage is each of the six? If each one is 12v, then that means you now have a 12v 240Ah battery, and you'd need a motor/cotnroller...

218mph electric motorcycle is legit.

I found this while misspelling a website name, but on the website, they claim to have the fastest electric motorcycle at 218mph. I was wondering if it is legitimate. I do know they have a lot of videos, but if it was that special, I would have probably heard of it. What do you think? electricmotorsp...

Re: I may be building an electric go-kart

Love the idea of a go kart. I can't speak to gear ratios. Those prismatic batteries are only good for 3 or 4C continuous discharge. So maybe 150A tops continuous. Which may be OK for your plans. I think they would get hammered on a race track. Any higher and you could be replacing them every season...

I may be building an electric go-kart

So I have a plan to build myself an electric go kart, but this is a very new concept for me making something bigger than the items I already have made. I have made an electric kick scooter with motors from an automatic toilet flusher, and also some little electric kitchen tools so I do not have to d...
