100,000 lbs if you gear it right. of course you would only move 300 ft in an hour.
maybe a little more info will get an answer that will help you out.

 

[The-Kid]

well if i get 120v a controler with 300amp's and get the right gear's i wonder if i can make a off raod kart with it and run 20MPH and cary 300pounds ??

Toystory should move this to the Electric Projects section. That board is gettin cobwebs goin on. haha.

On topic: Is a gasoline engine in your budget? An electric kart is going to require more than one large battery on it. And if you run out of battery, you're in trouble. I know you can run out of gas, but its much easier to get some gas from a friend or something than it is charge it up and ride it home.

 

[oldbikerarlo]

120v in batteries would weigh close to 850 lbs.

 

[Brandon1023]

120v in batteries would weigh close to 850 lbs.

Now add the frame which is probably ~150-200 pounds? Depending on the size. And now add the 300 pounds that OP said he needs it to be able to carry. We're lookin at something that weighs around 1200 pounds. Is that correct??

 

[The-Kid]

hmm i might want to re do this. hmm nvm i think a agree with you guy's i shuld nvm this project cuzz im still dont know sume stuff =/

 

[The-Kid]

hmm wat about four 12-volt lead-acid batteries, 1 8-kilowatt mars electric motor 6.4HP around , 26-inch weel's, and find the best gearing and fram about 150 pounds BTW this is for a tricycle. i also want to make a smal solar station in my back yeard to charge it lol but that is a side project umm this tricycle is for on road and i wana tri make it run for around 30-40KM. the controller i still don't know but maybe a Altrax programmable controller but idk yet . speed i hope more then 30KPH i wana tri get 50KPH or best 80KPH im wana pout 1250$ on this project maybe a bit more if is worth it. no suspention and im making the fram as light wight as posibal but still strong enuf. if you can help with this for parts and all i aprechiate it . thanks =)

 

[The-Kid]

so this is y i need to know how much can just 1hp can pull and wat is the math for it ?? and the watts i need to do it ??

 

[landuse]

It all has to do with gearing

 

[Brandon1023]

Exactly. You can gear it at a 2:1 ratio and you'll probably use up the battery's charge and probably not even get moving, or you can gear it at like 15:1 and pull a wheel burrow full of concrete. I don't know how these ratios would perform in real life, but the best thing to do is save up for an engine if you can.

 

[The-Kid]

i agree a bit but so i don't wast power or $ i need to know more then just gearing that y i need a way to convert or have the equation for turning 1hp = (how much can it carry) the gearing i think i know Wat ima do and wen I'm done designing the frame il add the schematics on in the forms then il ask for more help

 

[landuse]

There is no conversion

 

[r_chez_08]

8kw is way overkill. If you built a real light frame a 800w 36v motor could pull you fine you could also overvolt it to 48v and get 4 12v lead acid batteries and a 48v controller.

Please bear in mind electric is not the cheap easy way out. It is far cheaper going down to hf and getting a predator. However, if noise is an issue or you ^do not want a gas motor, go ahead!

 

[The-Kid]

8kw is for crusing and 15kw for start to get a fast go

 

[The-Kid]

and in total it will wight about 500 to 525 pounds

 

[matman55]

It all has to do with gearing

what will gearing help with if he wants to pull 560+ lbs(rider(s) included) off road at 20mph+??just wondering.

 

[The-Kid]

nvm on the off road just on road and total wight is 496pounds with rider and if i get 2 well maybe 600 around and i figured one part of the gearing i want to get Small to big then Small to big that wat i know at the moment not sure how big or how Small

 

[matman55]

i agree with brandon gas is the way to go,electric is clean and noisless but gas has certain advantages
-mobility(range in miles and ease of geting more fuel)
-powa! gas trumps electric!
-easy to repair.a 2 stroke golf cart engine is a heck of a lot easyer to repair without all the electrical mumbo jumbo
-the red neck appeal. what certified redneck or speed demon wants a electric engine! it just doesnt make sense!

 

[The-Kid]

y dose every one tell me electric in not the way to go idk i don't have the $ for gas and electric unfortunately is the futer so y not start now ??

i re calculated the stuff and it came to 238pound without me on it so


1"x1"x30'carbon steel bar 75$
1"x1"x20'carbon steel tube 50$
Mars Electric motor (4.8 kilowatts cruse (6.4 or 8.0 horsepower(15 kilowatts at a push) 498$
Alltrax programmable controller IDK yet wich one to get
four 12 volt lead-acid batteries or lithium nano-phosphate battery pack, idk yet which one to go with but the 12v acid ones 135$

(range of around 30 miles)

8.4 feet long
20-inch front wheel
26-inch wheels at the back

750watt solarpanels to charge

and one extra baterry pack of 4 more battery's


around capable of 45mph if i get the gears right

if you got bether suggestion pleas send a reply


if any one comments on gas engine pleas i know gas is bether then electric.only for sum stuff is wat i say to that
