what is the best e-bike kit??

[Racer_X]

I will make it easy for you Take this to get the best of the your motor.
48V 10AH Lipo 35A Discharge battery

If you want a more traditional style battery take this one, but it won't be as powerful as the one above.
48V 9.5AH Lifepo4 Aluminium Behuizing

I wouldn't recommend any of those batteries because the blue LiPo battery costs €500 and the silver one is just not good enough.

This is a battery I would recommend over the LiPo and it's €532 shipped to the Netherlands!!!

Do the Euro conversion on xe.com.

The ping batteries are really good, and my old 48V 20ah that I sold to a friend is still going 2 years later and still gives full capacity!

I just checked the date I ordered it, 15th June 2010 so I got it about a month later!. And it cost € 667.00

That battery should easily last 5 years compared to maybe 6 months for the lead acid, or 2 years for the blue lipo pack in the above pic!

It would suit the mac 8T with a 20-25 amp controller, the magic pie III or the other gm kit.

The mac kit being the easier to pedal, the ping battery is 9 kg, but the lead acid would have been heavier for much less capacity!

it is $818.00
battery is $658.00
shipping is $160

$818.00 = 620,27 euro

€650.00 I got on xe.com

Sorry I forgot to add shipping, I thought I did!

I'm just after looking at the specs again on the aluminium battery say 20 amp continuous discharge. ( I'm tired) Which is fine, but it would be hard on the battery, I don't think those cells are rated for more than 1C ? maybe someone with better knowledge than me can say ?

So 460 € for the battery and €219 for the motor kit = 679 Euro's! Just within budget.

The pro kit 901 motor kit controller will probably be limited to under 20 amps so it would probably be fine with the aluminium battery!

So racer_x was right!

You can get a rack for that particular battery that locks it in place, I'm not sure if the batter connections will match up!

You would probably need a torque arm too, just in case.

So that system will get you e-biking and be warned, you will spend much more in the future as you get the want for more power!

It should do 25-30 mph max, you might get 12 miles out of just under 10ah, so you will have to pedal a bit, remember the geared hubs are easier to pedal.

If you are looking at generic Li-on battery packs, you should be looking at BMS Battery.
Best pricing and reasonable shipping to Europe.

This is their standard 48V 1000W motor kit. I use the same motor but not their controller. It's a 470rpm motor at 48v. Never had a problem with mine and I've run 48-100V on it for a few thousand miles.
http://www.devi-motion.com/webshop/e-bike-kit/p-1/D1000080.html

I wouldn't get the MP for a couple of reasons. First, it's a low speed high torque motor of ~360rpm at 48v. If/when you want to go faster than 25mph, you'll have to start throwing lots of money and work into it. And I don't want an internal controller for what I would think would be obvious reasons. If you fry an external controller, it's a simple replacement. Fry an internal and you're screwed.
http://www.devi-motion.com/webshop/e-bike-kit/p-1/DE000650.html

As for batteries, I'm a lipo fan. It's all I will ever use until something more powerful for the same price comes along. Don't even consider sla. I don't recall what kind of range you want, but you can get about 10 miles per $100 using lipo @ 15-20mph. I wouldn't get a lifepo4 (2c max) battery unless you need a 15ah or higher battery. With lipo, you can as small as you want since even the cheapest ones provide 15-20C discharge rates and you probably won't need more than 6C anyway.

 

[o00scorpion00o]

The magic pie when fed lots of volts and amps is a very powerful motor! It needs to be fed properly, the MPIII internal controller is not that hard to replace compared to the MPII.

I can't tell you anything about bmsbattery's battery's, as I have never purchased one. There are mixed reviews here on E.S, I got a charger from them and it still works, that's all I got.

Their prices seem good though, I'm not sure how long the Li-Ion batteries would last. Their LiFeP04 48V 15ah is 8kg, that is heavy enough, but should last a good while. The Ping 48V 20ah is 9.9kgs and is more compact. The LiFeP04 should last the longest of all the batteries.

This battery here is smaller and lighter, but I don't know how long it would last, there are reports of them lying about the weight, but I can't confirm!

If I can remember correctly, I think they had some Anderson connector with the controller, but I'm not sure it would match up with the battery.

Those magic controllers are not that good!

 

[Racer_X]

parmenps, You ask BMS battery for: 45amp Anderson Power Poles connectors on both charge and discharge cables.
Then you get the Powerpoles crimper and put powerpoles on your controller. I think Devi motion can do that for you too when you order.
then you can plug them both together.

Noooo, that is a LiFePo4 battery.
You want one of the "Li-on" batteries.

He does if he want's longer lasting battery, but the Li-on is smaller and lighter.

Parmenps, just make sure the continuous battery current matches your controller, acceleration peaks also need to be taken into account.

 

[motomech]

We know little about the BMS Battery Li-on batteries, but the initial reports seem to be favorable.
We know even less about the LiFePo4 batteries from BMS Battery and I don't think the O.P. wants to be a "tester".
At the price-point of the Li-on batteries, if they lasted even a couple of years, they would be a "win".
But the question remains, how long will they last.

Maybe 25-30 mph max on level ground. I think it's a similar motor to the conhismotor I had. It was okay, but on 20 amps had little torque, so it used to slow down a lot on the hills.

You should get 20 kms max out of the battery full throttle. IF you need more range then maybe you could charge at your destination ?

Those GM controllers are only 15-20 amp max controllers and won't give you a lot of torque!

 

[wesnewell]

After finding this, I'm glad my kit didn't come with a GM controller.

The problem you have is that your battery choice can't deliver a lot of amps. Anything more than 20amps will be stressing it. So either live with this weak controller and battery or change both of them. Controllers are cheap if you shop around. I paid $35 shipped for my 72V 40A controller capable of 100V battery. Batteries aren't so cheap. And the battery you got is maxed out at 2C, 29A. That's one reason use lipo. Even the cheapest can produce 10 times the amps as 2C lifepo4 batteries.

 

[parmenps]

what motor and battery do you think I can best use.
because I really do not know what to buy

 

[Racer_X]

Depends on you. Do you want Plug and Play? I think you do, since this is your first build and may not have that much electrical or e-BIKE building knowledge.

motor:

battery:
http://www.fietsunie.nl/webshop/bat...57/48v-95ah-lifepo4--aluminium-behuizing.htmll

I would just keep it simple too those two first links for your first build. This will allow you to have a risk free reliable transportation for years.
When you get bored and want to upgrade it, then you can buy another controller and maybe some lipo batteries.

"EDIT" Here is a sample video to show how easy it is to plug a Magic Pie III which is the big brother to the motor you where looking at using the 48v battery.

Yeah I love my LiPo and won't change now unless something smaller and lighter comes along. That's why I Love it.

The LiFeP04 would be the longest lasting so there wouldn't be much in the difference in the end, especially by the time you buy the charging equipment, voltage monitors etc.

The LiFeP04 would be heavier and a fair bit bulkier, especially compared to the Zippy Compact! Cycle life isn't important to me, size and weight is!

This should work well.

I'd use 12s lipo with it. Should get you about 28mph top speed. 10ah should get you about 20 mile range at 20mph.

is this a goldenmotor but with a different controller

 

[o00scorpion00o]

Yes, that would be a better controller than GM's magic one.

It says no longer available ?

That would get you up and running, you just need a battery!

All ads are limited time. Just select your country and search for 48v 1000w. You will find current ads for it.

 

[o00scorpion00o]

Yes you can use that battery, you would get 25-30 mph max,

12 -15 miles max no pedal full throttle.

You need a rack for that battery too, I think they sell a lockable rack that you can slide the battery on and off. It would be useful.
