Hello!
I made a longboard this summer and I decided to make it electric.
I did some research, found all the parts that I need but I still have some questions.
The main problem for me is the ESC. Almost everyone uses 150A ESC's. (for example: http://www.ebay.com/sch/i.html?_odkw=EZRUN+150A-PRO+Brushless+ESC&_osacat=0&_from=R40&_trksid=p2045573.m570.l1313.TR0.TRC0.H0.X150A+Brushless+ESC.TRS0&_nkw=150A+Brushless+ESC&_sacat=0) But I only want to build a one wheel drive board. The motor only uses 60A and they are too expesive for my budget.

This is the ESC that I want to use: http://www.hobbyking.com/hobbyking/store/__8993__Hobby_King_Brushless_Car_ESC_100A_w_Reverse_Upgrade_version_.html

These are the motors: http://www.hobbyking.com/hobbyking/store/__18175__Turnigy_Aerodrive_SK3_5055_280kv_Brushless_Outrunner_Motor.html or http://www.hobbyking.com/hobbyking/store/__18123__Turnigy_Aerodrive_SK3_4250_500kv_Brushless_Outrunner_Motor.html

The ESC supports only 4s batteries. So can I use the SK3-5055 motor? Will it work if the motors voltage is 6~10s? And what batteries should I use? Can you recomend some?

This is the board that I made

You want to go for a higher rating that way you don't burn out your 60A and end up having to buy two ESCs.

I'd opt for a 63mm SK3 or a NTM 50mm. The 50mm SK3 are 6mm motor shaft and the 5055 is a much smaller motor. Go for the NTM 5065 (8mm shaft).

ESC only supports 4S so you can only use up to 4S. You need a 10S or 12S ESC to run 6-10S and/or just run a 6S ESC and run 6S only.
 
But the ESC is 100A. NTM 5065 uses max 90A and on the website it recomends to use 100A ESC. So doesn't tham mean that I would be fine using 100A ESC? It's just that I am on a toght budget and the 150A ESCs are too expensive for me, lol.
And can a 6s motor work with a 4s ESC? I've seen some people do that.

I'd suggest that if you want to build an eboard you can't even think about a 4s esc. There are more parts that you will need like a motor mount, drive train (pulleys, belts and gears) that can cost $200-$350. Have a look at other builds and do aome more research on the parts you need then tell everyone what you are getting. Sorry if this sounds mean, it is not intended to be.

You can't just connect a battery to a wheel and expect it to go.

Yes, I understand. I am a newbie to all of this. That's why I ask questions :D. And thanks for the answer.

But here are all the parts that I am planing to buy:

Trucks and wheels: http://www.ebay.com/itm/180mm-Reverse-Kingpin-Black-Trucks-FlyWheels-83mm-Purple-Longboard-Wheels/281796559271?_trksid=p2047675.c100011.m1850&_trkparms=aid%3D222007%26algo%3DSIC.MBE%26ao%3D1%26asc%3D20140602152332%26meid%3D786d8ce7a8f64b138ca99a8280037da4%26pid%3D100011%26rk%3D1%26rkt%3D10%26sd%3D281796424764

Motor: http://www.hobbyking.com/hobbyking/store/__22036__NTM_Prop_Drive_50_60_270KV_2400W.html or http://www.hobbyking.com/hobbyking/store/__18175__Turnigy_Aerodrive_SK3_5055_280kv_Brushless_Outrunner_Motor.html

ESC: http://www.ebay.com/itm/Hobbywing-QUICRUN-WP-8BL150-Waterproof-150A-Brushless-ESC-For-1-8-RC-Car-Buggy-/261736028762?hash=item3cf0aeda5a

Battery: http://www.hobbyking.com/hobbyking/store/__8586__ZIPPY_Flightmax_5000mAh_6S1P_25C.html

Controller: http://www.hobbyking.com/hobbyking/store/uh_viewitem.asp?idproduct=44693&aff=877196

Charger: http://www.hobbyking.com/hobbyking/store/__5548__IMAX_B6_50W_5A_Charger_Discharger_1_6_Cells_GENUINE_.html

Only things left to find are pulleys and a belt. The motor mount I can make at home. What do you think of this config?
 
That looks good. Maybe get Caliber II 50 trucks because they have a D shape which will be easier to make a mount for.
Motors are good but you may want more torque. Enertion's R-SPEC motors are a great choice if you want to have a pre made motor pulley mount solution. They are also made for eboards so that's a bonus. Other then that good build!
 
You can also get VESC from enertion. Made for eboards and heard great things about them. Don't climb hills with 6s you will need 10s for hills and an ESC that can handle 10s (VESC or torqueboards 12s ESC)

Remember you will need a power supply for the charger as well. I bought mine on ebay, they also have them on hobbyking.

If you get an ESC without an UBEC, you will need an external one to power the receiver for the remote.

Also regarding the battery. Two ZIPPY Flightmax 5000mAh 3S1P 20C will cost about the same, and you can arrange them so it's more of a flat battery.

Yea, I know. I think this will be ok http://www.ebay.com/itm/Original-SKYRC-15V-4A-60W-Power-Supply-Adapter-for-SKYRC-IMAX-B6-EU-Plug-N97N-/371435938131?hash=item567b4ea153
And why does this charger have AC and DC inputs? Doesn't it has a built in powersuply? I'm confused :D http://www.ebay.com/itm/Imax-B6AC-LCD-Screen-Lipo-Nimh-Nicd-RC-Battery-Balance-Charger-Discharger-EU-Plu-/271551072479?hash=item3f39b488df

I don't have any hills where I live so I think that's not a problem :D
 
quicrun esc is a good choice: I have been using that esc for the past year, and haven't had a single problem.
 
That charger doesn't have a built in power supply but the version 2 of that charger does.
 
Are there any other smaller controllers? Like boosted board has this small, compact controller. I don't like the one that I am planing to buy but I haven't found any others. I know some people use a Wii controller. But I don't like the joystick. And smartphone controller isn't comfortable because there can be missclicks and if you fall, then the smartphone will get damaged. Any suggestions?

But then what is the AC input for? :D

Seems like it, but I'm a bit confused about the "1.5A"

Get the bad wolf enclosure for the gtb2 remote. About as good as it gets right now or until we get a slidepuck/remote going.

Lox? 6s is perfectly capable of climbing hills..Myself and several others have multiple builds with single motors @ 6s that rock overpasses and most city hills. SF is a whole different story, But I weigh 205 and my singles don't struggle up any hills I've climbed in the miles I've put on my builds. I would put my 8s build up against anybodies build and it's a single 63.

The sole reason for 8, 10 and 12s is for efficiency higher voltage/less amps = Less heat. I.E. more longevity out of your components.

You don't have to invest above 6s to have a beast of a board. 22v will knock anyone on their arse who's not paying attention. Trust me!

You can climb hills in SF with a dual 6S setup..

Got a new mini controller - http://diyelectricskateboard.com/product/torqueboards-2-4ghz-mini-remote-controller/ I should of added a photo of the Nyko Kama too.

Ok thanks psychotiller. I have heard a few people get some magic smoke from their motor if they start on a hill. So maybe get some momentum first.
 
Can somebody post a link on where I could buy pulleys and belt? I would be really thankful :D I'll be using NTM 50mm motor and the shaft is 8mm
