I want a opinion on these set of parts im thinking about useing for a board, at the moment, i want something that I won’t have to upgrade heavily after initally building it Motor:

Esc:

(do i need this card?) https://hobbyking.com/en_us/hobbykingr-tm-programming-card-for-car-esc.html

Controller: this http://www.enertionboards.com/electric-skateboard-parts/nano-x-enertion-2-4ghz-controller/ or this https://hobbyking.com/en_us/hobbykingr-tmhk-gt2b-3ch-2-4ghz-transmitter-and-receiver-w-rechargable-li-ion-battery-1.html

Batteries: https://hobbyking.com/en_us/multistar-1400mah-3s-65c-with-led-indicator.html im thinking about this but I don’t know if this isn’t enough or if i need 2 or just a bigger battery in general something like this https://hobbyking.com/en_us/multistar-high-capacity-3s-3000mah-multi-rotor-lipo-pack.html

the thing that connects to the wheel and motor finally I want help with pulleys because out of all the options from people who do e boards I think they all look over priced is there any way for me to find a cheaper solution? I have access to a drill press and clamps so it shouldn’t be a problem for me to drill a few holes in it.

The board: https://www.amazon.com/gp/product/B01EOUWUT0/ref=ox_sc_sfl_title_2?ie=UTF8&psc=1&smid=A2JNVCIL8HXZDH

Please help me for real

What is your budget and how heavy you are. Where Do you live? EU/US/AUS/? Basicly motor and remotes are good but everything else waste of money.

109

Batteries are too weak. Go for at least 4000-5000mah else you won’t get any range. 2x3s Zippy LiPoly are decent for a first build.

I weigh about 200 pounds and live in the us. Im aiming for the low 400$ range but can spend more if it comes to it

111

So what kind of Esc should I look for? And what kind of drive train thing should i use as well?

And thx for the feed back on the batteries would this work?

also I found these and thought this would be a good alternative

https://hobbyking.com/en_us/zippy-flightmax-5000mah-3s1p-30c.html these x 2 or 20C which is cheaper.

Drive train you have to figure out yourself with that budget. I bought pulleys and belt from beltingonline (UK) and drilled holes and ect. by myself.

Question: I am installing a VESC to my Magneto 1 (backfire) I am setting up the voltage cut offs and i wonder how many cells my battery is? And what cutoff levels i should go for.

I see 5 white, 1 black wire on the balancing wires, is that 6 cell? Can you tell from that? Pictures: http://imgur.com/a/Ga338

If it’s 6 cell im thinking going for 6 Cell x 3,4V = 20,4V for cutoff start and 6 Cell x 3,2V = 19,2V cutoff end, or could i go lower than 3,2V?

I have a question about 18650 setups, or more specific the batteries.

How much does the discharge rate ( max continues) matter - Most people I see use the Samsung 18650-25r 20A batteries but when looking at some E-bikes I see that they contain Samsung 18650 5A batteries instead?

is 5A to low for a E-board and if so why does it differ from the bikes?

You can wire batteries in parallel to increase the current output

parallel wiring increases battery capacity current output = capacity * C (discharge rating)

116

For me it’s about demand. The better amperage you can deliver the better throttle response.

Am I the only one having problems disconnecting an xt90s. My xt90 is very difficult to undo. Any fixes for this?

118

I have Noob Question. I bought 4.12 vesc from Enertion. I have 10s li-ion battery and sk3 6374 motor. Can you write step by step guide what I need to do next?

119

This forum really need step by step guide for beginners. Here is good threads all around this forum but nothing like this. And is should be pinned.

Name would be: Esk8 build for dummies

This one is real mess. Clear and simple step by step is what newbies need.

A simple solution is to lightly sand the female XT90 around all the edges. Be sure to use a fine sandpaper so you don’t remove too much material. This video is for XT60 but should be the same idea.

Got another question regarding 18650 batteries and soldering them, I see that some companies, NKON for example offer to solder U / Z soldering tags on the batteries before they ship them. The strips on the tags diemensions: 30x7x0.12mm.

Isnt it a possibility to decrease the heat transfered to the given cell that you get thoose tags and solder onto the tags and somewhat decrease the possiblity of heat getting into the battery?

For someone wihtout a Spotwelder this would be as soild idea? or is the tags themself gonna heat up when battery is in action due to being to thin?

I’ve been doing some reading, but still don’t really understand sensored vs unsensored motors, and where does the sensor wire connect? What does the sensored aspect of the motor do exactly, and can you run a sensored motor without using the sensored wire?

search for wiring diagramm, there are a lot of good things online here
