100cc brushless electric scooter doing weelies

100cc brushless motor mounted in a Toy's R Us kids scooter powered by dead Mac Book Pro batteries taken out of the garbage. i reconditioned the batts and built a 34 volt 250 amp draw 35 amp hour battery. Installed a 200 amp Coolrunng Brushless speed control. top speed 34 Mph 0 to 34 in 5 sec can climb a 25 % grade +++ at 21 Mph and can run well over 40 miles without needing a charge.

ahhh buddy i wish it was that easy:( but yes that is same scooter as u i bought it at wall mart for my daughter scooter batts died in 2 weeks. i been designing brushless systems with some best code writers in the world for 10 plus years. my point is i make it look easy and safe. IT IS NOT that scooter is way to fast for that chassis and it will just throw u off if u stabb the throttle. that said i can make a good batt from Mac batts out of garbage if u wont more info contact me

badass scooter :)

@shinyfuzzy thanks, its really easy to build and crazy fun!!!! only problem right this sec is no one makes the motors anymore.... cant even find a used one on ebay... so we are looking into building them ourselves.. will see i hate winding motors ....

[shinyfuzzy]

@wherebsara i just have one question. how do u know its 100cc? i didnt think u could measure electric by displacement

[wherebsara]

@shinyfuzzy well the web site that i bought it from listed it in the specs, i did not really care one way or other it was cheep and i could always rewind the motor if i needed. but all my test have been right in the ball park +- 7% for 50 bucks i would expect A LOT worse. just for the record 100 cc is only about 9.5 HP +or - 20% ruffly. A short answer i just took max watts i drew =7000watts and used Iphone power conversion app=9.383Hp. hope that answers your question???

[shinyfuzzy]

@wherebsara i get the 9. watever hp but im pretty sure displacement only applies to engines and not motors. if that is 9hp u should gear it for like 60 mph lol

[wherebsara]

@shinyfuzzy i get it. a lot of ppl are new to this & brushless is growing fast. ive been building prototype chassis, Government pro types & beta testing brushless ESC for arguable the best code writer in the world for 10 years. i understand u wont to show how much u know, everyone goes threw it. but then i met & started to work with the heavy hitters in brushless & quickly shut my mouth & opened my ears. I post to pass on what i have been given. my time is valuable i try to make things simple

you could embarrass people that have gas scooters with that scooter's speed/acceleration.

you said you used old computer badderies? could you make a tut on how you made it or explain how you made it?thanks! ps i have an ezip 400 electric scooter it looks like the same one you used how did you make it go faster also?thanks again!

@wherebsara so i tried to look this up on google and i think what ur saying with the displacement is right, but I'm right also. we're just talking about completely different kind of displacement i guess
