New Build parts list

[nlfletch]

Hey there all,

Been reading a shit-ton of info about boards over the last few months and think I'm finally ready to pull the trigger on some parts. I was hoping you all could give me your input. I'm 6ft. and weigh 185. I live in the bay area and am looking for something that will top out around ~25mph and take me up some hills. Nothing crazy, just mellow grades. I thought I'd start with a single motor high-powered setup, then maybe upgrade to dual down the road. I don't need really long range but I'd like to get about 10 miles minimum. Also, it can be a bit wet around here. Any recommendations for waterproof cases that will fit the ESC/batteries? Do I need to worry about overheating with something like that?

Parts List:

Deck: Generic blank deck from eBay with a small kick tail. 40" L x 9.75" W

Batteries: QTY. 4 - ZIPPY Flightmax 5000mAh 3S1P 20C. Looks like HobbyKing is back-ordered, though I saw them on eBay in "new" condition. Safe bet or no?

Battery charger: HobbyKing™ ECO6-10 200W 10A 6S Bal/Dis/Cyc Charger w/ acc.

I plugged in the numbers to the calculator I found here: http://toddy616.blogspot.com/2013/07/electric-skateboard-calculator.html

LiPo Cells: 12
Motor kV: 200
Efficiency: 70% (used his recommended number)
Gearing: 20Tx44T = ratio of 2.20:1 (based on the last availability I read about from DIYelectricSkateboards)
Wheel Size: 83mm

Gives me a battery voltage of 44.4v
Motor RPM: 8880
Weighted motor RPM: 6216
Top Speed: 39.24 mph
Weighted Top Speed: 27.47mph

Any suggestions or substitutions? I know the iCharger would be nice, but I was thinking I could upgrade down the road and use the HobbyKing one at work eventually.

Thanks for any and all input, I'm totally overwhelmed at the amount of info on here!

The HK charger is only for 1-6 S. You need 12S, so it looks you're going to have to shell out for the iCharger. Also, try to decrease the rear ratio or reconfigure the motor into star connection instead of delta to decrease the kv and increases torque to climb hills. You don't really need 27 mph imo. 20 mph already feels very fast to me.

While it's great you did some reading, np127 you still have a ways to go before you start dispensing solid info. Most of the people who use an icharger charge 12s as 2 paralell 6s. In fact I'm thinking they don't even make a 12s charger. I hear the eco6 actually a good charger.

The kv is perfect on the motor and rewiring it would be bad. Gearing for a 20-24 max unweighted speed would be a fine choice.

I also bought the 12s single motor kit off DIY and i topped out at 26mph with 90mm wheels and a 44t to 16t which gave me a 2.75:1 and I weigh 126 pounds. I used to run the 170kv motor and my god its torquey. Made my board lift a little, but now im running DIY's new motor the 230kv for hills. 12s is way crazy especially on the low kv. I would recommened detuning it with the programmer that the kit comes with med. acc and low timing (but its up to you ). Also 150% to 200% acc setting on the wiiceiver is perfect, i dont remember seeing an instruction for setting the wiimote. But thats on the web if you type in wiiceiver and its the first link on google.

Good luck on your build!!

I have 16T/36T which I prefer. I also suggest a motor with 230KV or so. I fly up hills much faster with 16T/36T 230KV versus a higher gearing setup.

I recommend the 2.4Ghz Mini Remote. Really reliable, small controller.

You can use (2) 6S packs and wire in parallel to charge. If you can flex the cash spend the iCharger 208B is the best bet. You'll only ever need to buy a charger once.

I thought it was 12S because he used 12S in order to get 27mph in the speed calculation. If he did it in parallel, wouldn't it only be 6S with double the mah capacity? But what do I know. Also, Thunder does sell 12S charger, but it is out of stock at the moment. Last thing, you don't have to rewind the motor when you switch it from delta connection to star connection. You do have to open it though. It would reduce the kv by a factor of 1.73.

He doesn't need a 12s charger. He can charge all 4 of his batteries at 3s 5amps using the parallel charging board. He has 4 3s batteries if I'm correct and he will be wiring all those in series to get 12s 5000mah.

You're still not quite adding correct info,

You said he needs an icharger, and they don't sell a 12s charger... Not that he needs one.

I didn't say rewind, if you look what I read I said rewire. And that would be a bad, bad idea. You're taking things out of context, and you don't really understand what you are giving advice about.

iCharger 208B is capable of 8S. You probably wouldn't use a 12S (single) battery. Typically, you would use (2) 6S batteries and wire in series for 12S.
