How much you knew about the E-bike batteries ?

Re the banner ads, for various reasons many people use ad block software and may not have seen the banner (and those that have seen them may have automatically mentally filtered them out). Which is why it helps if people identify themselves with their post ~ as per Wisper etc.)

 

[Gens Ace battery]

I still think there is an element of spam in this. I have found a further two places where an apparently identical post has been made by a poster from Gens Ace Battery, so that at least 4 places spammed with this post.

One way of pushing your product, I suppose. A bit of searching reveals this is the parent organisation: ABOUT US . I don't find the name Grepow when searching this forum, so it may be new to members. They have not been in Li e-bike batteries very long.

The website above has some pretty slides explaining the technology. As the posts by Neptune and others suggest they need some fact checkers to monitor their employees posts here.

Yes. we copied this post to other E-bike forum in different countries.
we sponsored many forums, but we just want to share it to others in different countries.
there are nothing special.

Yes, we are still new for E-bike battery. Grepow is our factory's name.
we have came to E-bike for around 1 year. Before E-bike battery, we was moving on other electronic market.
Gens Ace this brand shared good reputation in RC hobby battery market. we are keep learning for E-bike market. We are coming here with our honest and faith. we are here just want to let you guys know us, know Gens Ace are coming...

Thanks.

They are relative newcomers known in the radio control model market but from the voltage sizes now on offer seems like they are trying to attract the ebike market too.

Lipo 12S-44.4V - Gens ace

Hey,

For radio control model market, Gens Ace are not the newcomer anymore.
We has the good reputation in hobby's market, and we are powerful in USA and Europe.

And for that 44.4V battery, it is only designed for RC helicopter.
Russell put wrong weblink to the banner, gensace this sale web is not the one which we want to show here.

Thanks.

But they describe it as expensive that is obviously untrue,hence my posting.

Hi Dave,

As I said LiMnNiCoO2 and LiFePo4 this 2 type batteries are the most suitable for E-bikes. Maybe I haven't described it very clearly. Anyway, I agree with your ideas about the LiFepo4 batteries.even we are the manufacture of that 4 types batteries. For now, some of the brand E-bike suppliers are truning to the LiFePo4 type. especially, the E-bike kit suppliers.

For the price part, Compare with that 2 type batteries, The price number of LiFepo4 battery is really bigger than the LiMnNiCoO2 batteries. But if peoples think of it deeply,the LiFePo4 is cheaper than other type batteries if take the cycle life cost into your consideration.

Thanks & Best Regards.

Well I hope they are monitoring these posts and come back and clarify their position.
I welcome other manufacturers joining the forum, more so battery manufacturers, the more the merrier.

Yes, I hope so... we just want to know more individuals ideas from the forum.
then collect it. it will be very helpful for our development. That is what I want. That is why I been here.

Thank you. shemozzle.
have a nice day.

Who is that? Benson, Robin or Susan, or even Kelvin Ouyang? One person using different names on different forums or four different employees making identical posts? Correct this spam-like behaviour and then you may get more people reading your posts.

The German pedelec forum seemed to regard Susan's post two weeks ago as rather spam-like. I can't read German so I used the Google translator to try and understand the comments from the German users. A Google translation of some of the replies at Teach you something about E-bike batteries. produced some rather broken English (with some clear mistakes as is usual):

Hello
Nice collection / dissemination of known facts and also known errors and half-truths / invalid generalizations

Better yet, it would be in German, with English because wirds but very tedious, and I still think you should your obvious business interests here also speak openly and not creep up on Hintereinang an ostensibly technical discussion.
*****
English is ok, Susan may just not German ... Your account has been marked as a manufacturer.

I do not know if this should not even be considered as spam forums. as someone logs on to per copy + paste unload his stuff he has been dumped into other forums. That's probably also already. And yes, even if you can not directly detect: it is about commerce.

Like the German forum members say, and you admit above, what is behind your post is commerce. You say, "Gens Ace is coming." We have been warned, and I call it spam. Fortunately I can make use of this forum's ignore facility to block posters who generate too much of this sort of thing.

Of course, you have freedom to call it as spam and you can ignore it. but not everyone are knowledgeable about the batteries. we just want to share it and some peoples who are still fresh for E-bike battery may think it is useful.

As I said we are interested to collect the feedback and information about the E-bike or E-bike batteries from the forum. The consumer individual's opinions are very helpful for our development. you can call it as commerce, that is your freedom.

So what did you think of my home made battery

neither would German forum tolerate the like of some members on here, who blatantly encourage and discuss illegal electric moped use. They would get short shift...

and before anyone says it, any of the High power bikes I link require insurance and registration etc....

Yes, but I was under the impression that people do not bother with insurance and registration for their high power or otherwise illegal e-bikes.

Kelvin,
I wonder whether you tried to get your technical people to check what you wrote. They ought to be able to give you some good feedback on its accuracy, as indeed some of the very knowledgeable members here have already done.

I read the blurb on your website put out for the Shanghai Exhibition in April this year: Grepow lithium battery shows its appearance at 2012 Shanghai International Bicycle Expo.

We have more than 5000 employees which include 3 Doctoral candidates, 5 Master degree candidates and 150 professional battery engineers & technicians

I don't know whether something has been lost in the translation to English, but when you refer to doctoral and masters candidates, in correct English usage it implies that these people are still studying for their doctors or masters degrees. If they had been awarded their degrees they would no longer be candidates!

If you have 3 people with PhDs and 5 with MScs in your company I would advise you to go first to them to check the technical aspects of what you write before posting it in several forums on the internet.

On another tangent, I am really curious over your name Kelvin. Is the name Kelvin common in mainland China? Where does it come from?

As a physicist, I first became aware of the name Kelvin from the absolute temperature scale, and then discovered that it was Lord Kelvin in whose honour the unit had been derived. Now Lord Kelvin was actually born plain William Thomson, and it was only when he became ennobled in 1892 that he chose the title Baron Kelvin of Largs. The Kelvin was actually the name of a small river running through the grounds adjacent to Glasgow University where Thomson had his laboratory.

Suddenly after 1892 people Britain commenced giving the name Kelvin to their children. I have always imagined that the name arose via Lord Kelvin from the Scottish stream. Now I have come across a number of Singaporeans called Kelvin, and also one person born in Sarawak, but he had a strongly Christian background and I thought it possible that he had acquired that name in some way as a result of English-speaking missionaries.

Hi Benson,

Back on topic.

I have an interest in Ebiking and several years in electric flying, mainly fixed wing not heli's.

In RC we have excellent tools to control the condition of the Lipo battery:

i. Two means of charging the battery, direct or through the balance cable.
ii. Dual chargers.
iii. Battery balance units.
iv. Battery discharge units.
v. Battery monitors.

As the battery on an Ebike is one of the most expensive component parts, do you think that it would be a good idea for the current Ebike battery designs to be modified to incorporate some of these control tools into the battery assembly so that the user has more control over the conditioning of the battery, thus preserving its life and reducing the customer returns if the battery goes out of balance?

I know this would mean the standard Ebike battery charger would have to change to dual charging but all it would need is for the existing RC chargers, balancers, dischargers and monitors to be upgraded to accommodate the increased cell counts required for Ebike batteries.

Eddie, I think what you meant to say was "short Shrift" , which means a short time given to a condemned man to confess his sins. Short shift is some thing you do on a motorcycle, when you change to a higher gear before peak RPM. Just me being pedantic..

 

[flecc]

Hi Benson. One regular request that crops up in here is for in-frame replacement batteries that can replace more expensive original suppliers items. Obviously this could only be done for the most popular models and may involve design rights issues. However, it may be of interest for you to look into this possibility.

Alternatively and avoiding the design rights issues, perhaps you could supply replacement battery pack inserts complete with cells and BMS to fit the cases of the most popular expensive e-bikes, enabling owners to simply swap the contents over economically.

 

[Scimitar]

Enough of Gens Ace Battery - I reserve judgement for the moment, but I'm not impressed by sloppy inaccurate spam. It remains to be seen whether their batteries are any good and if so, how much they are.

Neither would they tolerate your crap-stirring posts. You'd be out on your ear, after a warning or two.

 

[Gens Ace battery]

So what did you think of my home made battery

Regards

Jerry

Hi, Jerry...

Your battery is good. that is A123 batteries.
A123 batteries are always going with high quality and nice reputation.
Especially the discharge rate of theirs cells. As I know there are no Chinese supplier can beat them.

May I know the power your motor ? and how long the battery can work after the fully charged ?

Thanks
Benson

Hi. yes, that is good idea. Sometimes, I am thinking myself that the E-bike is very similar with the Radio control product, such as the helis, or the fixed wing, ( we called it as Multi Rotor or Quadcopters). I call it is similar because the E-bike have a controller to control the speed of the E-bike, just like for the RC product has the ESC for its speed or other function. but actually, they are different, RC product are controlled by the Receivers. for the E-bike, you need to ride yourselves.

For your ideas. actually, Some of the battery BMS has the function of the battery balance. the cells will be balanced when it charging...Most of peoples has the problems with theirs E-bike battery, and 60% problems are the BMS problem. for nowadays, almost all of the batteries are built with the BMS. Maybe the BMS should be built with the E-bike controller.

and for your idea of using the RC chargers to charge it and balance it. Actually, there is one E-bike supplier who is from Austria had made it already.

I found theirs information on Eurobike show this year. And theirs bikes and battery looks good.

Biketronic E-bike
Biketronic E-Bikes aus Österreich - Akku

You can learn something from the picture in the link. theirs battery is charged by the RC charger by the balance connector. I think that is what you want. And I think theirs battery BMS is going without the overcharging protection function. because they do not need it, the RC charger can protect its overcharging and it can balance the cells perfectly.

Thanks
Benson

Hi,

Thanks for your suggestion. yes, we have noticed it. The only problem is the battery frame.
If we can get the same frame,I think the copy BOSCH or Bionx battery is everywhere in the market.
they have the patent. I do not know whether it is allowed to design a similar frame with the same connector, or make the size bigger or higher...

There is another solution that we use different frame to build the same specification batteries. the best frame is the rear back battery frame. It is easy to connect and can be build with different specification to replace your original battery. but it is risky. we do not know you guys can accept it or not. because it will affect the sign of whole bike. just like you put the Panasonic rear rack battery to triangle BIONX E-bike.

Thanks & Best Regards,
Benson

heh.... I have transfered your words and good story to Kelvin...and he refuse to answer why he is called Kelvin this name. yes, Kelvin this name is not special in Chinese Mainland. The culture of Chinese English name is not like you, your English name is given by your parents or relatives. but we are not. the English name was given by ourselves, parents only gave us the Chinese name. And the Chinese can not be translated to English. So... Some of our English name are given by our First English teacher, some are given by ourselves. Just like some USA people want to have a Chinese name when they arrive China, then they will find good given name theirselves. never thinking about the history of the name.

Ok. that's all for the name, you will find more things interesting when you come to China.
Let's go back to the topics. I do not deny there might be some mistake in my post. if you found there are something wrong, you can find it out and correct, I will appreciate it and it will be impressed to everybody here.

Thanks
Benson
