Suzuki GT50 Conversion

[only1jake]

I really love your imput guys!
I have found 6 DeWalt 18v 2.4 ah for around $350 USD! http://www.trademe.co.nz/Building-renovation/Tools/Power-tools/Drills/auction-272407924.htm
If these would have enough amperage, i could maybe have 2 packs of 54 volts in parralel?
What do you think about the batteries? Or would i need a higher ampere?
thanks
Jake
Edit: http://www.trademe.co.nz/Building-renovation/Tools/Power-tools/Drills/auction-272160672.htm i found these ones?
Ive heard about makita are good? ::http://www.trademe.co.nz/Building-renovation/Tools/Power-tools/Saws/auction-272161610.htm

Jake,

Those Dewalts have NiCD cells not the A123 LiFePo4 cells. ie not what you want. WRT the Makita's I just got 24 Makita packs from DoctorBass for $336, ie $14/pk and they generally have 8 out of 10 good cells in those 18.5v3ah packs. SteveO has A123 cells listed in the for sale section with some of the soldering already done for you. Current-Pille has big quantities of Bosch & Dewalt packs really cheap in the for sale section.

Kelly order won't ship till next week= see about trading up to a higher power controller to better match your motor. Ideally one that also permits a range of voltage operation including higher, so you aren't stuck at 48. Higher amperage too due to Kelly's over rating. If it takes giving up the $200 controller and the converter to put that money already paid to a better controller, that's money much better spent, and you can easily replace that capacity locally.

Batteries are an investment. You're the one talking about budgetary concerns. If that local lead source is nearly free that's great for testing. For your commute, you're going to need at least 50wh of rated capacity per kilometer for lead and that's on the low side. Thats voltsXah=wh , so talking about some tool packs totaling a 259.2wh of capacity in total for $350usd clearly isn't sufficient.

Everyone has given you solid advice, except the idea that just 20ah of Thundersky cells would be sufficient, capacity maybe but power no way. It's now up to you to do your thing. If you do end up getting some used Makita packs I'll give you a step-by-step process of what I believe is the easy way to harvest those cells. Other than that I'm done here.

Good Luck! I hope you figure out a way to unleash the full potential of that motor, because that and your donor bike are what are solid in your build. I know there are a number of people waiting to hear about performance results for those motors. The controller will work, but probably a bit lackluster in performance. The rest is stuff that can be scrounged for cheap. Batteries are still ? despite being a make or break part of the project.

http://www.toolking.com/dewalt-dc9280-2 ... no-battery You will need lots of them but they are near the best. If I had it to do over again I would have saved and bought the good stuff first thing.

I have thought about it and understand where you guys are coming from. I have sent this email to kelly controllers:
Hi,
I have been thinking, and since the order has yet to be shipped. Could I change the Keb controller i currently have for this: http://www.newkellycontroller.com/product_info.php?cPath=24&products_id=564 .
Because the controller i currently have ordered does not fit my needs. Since the price is different could I *Not have the charger. So like this:
- 1 x KEB48300 150A 48V 3KW -$209.00
+ KEB48600 300A 48V 6KW +$349.0
= $149 more
So Minus the charger aswell!!
- 1 x F4815-48V/15A Charger -$199.00
That equals to $59 + which can be refunded?
So the order comes to:

1 x Low Cost Compact Assembly (KEB/KBL/PM ) $99.00
1 x Kelly 48Volt Charge Meter $19.00
2 x Throttle Hall 0-5V Twist Grip(WUXING) $38.00
1 x Optional Waterproof $38.00
1 x KEB48600 300A 48V 6KW $349.00
1 x HWZ Series DC/DC Convertor 48V to 12V 300W $129.00
1 x Hub Motor 48V3KW (High Speed)(disc-brake) $399.00
1 x Kit for Disc-brake Motor(big) $99.00
1 x Motor Tyre (13-inch motor special) with Vacuum births $79.00




$59 USD to be refunded!

Sub-Total: $1,249.00
Table Rate (Best Way):
Total:
$277.00
$1526.00
That is what i would like for my order! If this cannot happen. Cancel my order and i will reorder again!
Thank you
Jake

I will be rethinking about what im going to do with the batteries!
Thanks,
Jake

[only1jake]

So I'm going to have a 300 amp controller. And some spare cash. Which means i have more to spend on batteries, but i will also need a higher amperage. So that would equal to more speed and torque. Better and lighter ride. I'm going to think about what some of the members have said and do some more research. And decide which Lithium batteries i am going to use. Not going to use lead. Maybe get some for near free to test.

thanks,
Jake

Edit: Just got a reply from Jane, Says it is no problem!! which is great! I'm excited now to use lithium!

[only1jake]

Hello,
I've now made my final decision on batteries, and have realised that you have to invest in them. I am going to aim for this set: http://elitepowersolutions.com/products/product_info.php?cPath=26_33&products_id=106 which has everything i need and would be ideal for the project. I have a motor and controller and everything else. Just need the batteries, bms and charger. And this set looks great. It probably saves me money. Note the free shipping.
Thanks,
Jake

[sjoerdvdd]

Hi jake,

I was woundering what you've paid for shipping?

[only1jake]

In which order?
I'm not ordering the batteries yet, i have to save up!
on the website it says the shipping is free!

Good chose, that's where i got my packs.

[only1jake]

Just a small update.
Kelly claim they will be sending the gear at the start of march, because they have to 'make' the waterproof controller etc.
My parts from evworks should be here next week!
Ill take some photos when some stuff arrive.
Jake

[only1jake]

The order is on its way!!!

[only1jake]

Hey Guys,
I'm very excited because the order from kelly controllers has arrived, although i wont be able to test anything for a while, since i have no batteries.
Here are some pics of unboxing and the hub motor and controller etc. :









ENJOY!!!!

[only1jake]

More pics: Enjoy!








More to come!

[only1jake]

here you go!

[only1jake]

It was all packaged very very well, no damage to anything at all, considering it flew over nearly half the world lol!!
I just cant wait to get the batteries.

[morph999]

Jake, can you tell me where you bought the hub motor? It didn't come with the wheel on it, did it? Did the hub motor come from Kelly ? Also, what is the black box? Is that your charger? Also, how thick is the axle on the hub motor...could it fit on a bicycle?

[only1jake]

Hi Morph,
I got the hub motor from kelly controllers, its the 48v 3000w version with high speed. I ordered the wheel and tube with it, and since i ordered them together, they fitted it for me. They also fitted the controller on the assembly. The black box is the dc/dc converter, 48v down to 12v, its bigger than i expected though. I'm not too sure how thick it is, but its the thickest axle i have seen lol. Its bigger than the one on the gt50 and my old gn250, you would just need to modify the bike a bit!
Once i get my batts, which wont be for a while i will do some testing and vids!
thanks,
Jake

[only1jake]

Hi,
Can anyone help me with my problem. I also bought a kds 24-36v 100 amp controller and i am having problems connecting both the wuxing and the magura throttle>???
I cant seem to get the wires right, can anyone help?

[orpheedulogis]

Hi.

I did about the same than you ( http://www.motoelectrique.unblog.fr ) and I think acid battery would not fit for this.
The 3000W motor need more than 60A in some case so, if you use 20Ah battery, you need it can support 3X discharge.

A question: I ordered and received the 3000W motor and would like someone explain me how to install brake disk kit.

Thanks

[only1jake]

Hi,
I am not sure how to fit it yet. It seems really weird. I am still saving up for the lifepo4, but i think in the next couple weeks i will start to fit everything.
I a going to be using thunder sky 40ah batts.
Jake

[orpheedulogis]

only1jake
OK, if you find tell me !
I try to see how to do but doesn't find.
In case of there is someone here who has an idea for placing the parts: on the following picture, I don't understand how I can put the metal plate in my hand (I just put uppon the hydrolic system on the disk, not fixed)



I send an email to kelly so they give me informations about this. if I have, I will display here.

[only1jake]

Thanks for the pics.

John, I upload mine to imageshack and just post the link here as an img and that works. As for the brake your explanation is good, its just a bit hard to understand without having a picture.
Thanks

[only1jake]

I forgot to say, on image shack you get a special code already done, with the site address. You just copy that in.
Picture works, but that is a completely different setup I tried quite a few times, could not get the right position. Ill keep trying.

Gardens in wellington are cool. Lol.

[orpheedulogis]

John.
Perhaps my english is too poor but I don't think it can fit.

"The long oval slot goes over the axle and is vertical"
If you do so, this mean motor axe is in the wrong position (you can't the wheel in).
Second, where do you put the big hole ?
There is also the problem with screws : there is no correct position because total lenght will be too long.

But ... I just received informations by Kelly !
I don't really look at them actually but here are the pictures













I don't think the metal plate is used ... isn't it ? hem ... it is

For me, that's mean ( for the 3000W motor )
- I have to increase big hole so axe will be abble to go in
- I have to cut so the metal plate go exactly for parrallel disk brake position

Do you think I'm right ?

[Jay64]

John, this actually is a public site right here. You can upload the pics right here. Have the pic saved on your comp, when you post a reply, below the reply box is the "Upload attachment", you can browse your comp for the saved pic and then add the file. Just FYI.
