another changing to tubeless question

[terry2]

Hi this is Mark from RJ Energy.
We are lithium battery manufacturer in China.
I am happy to help if anything question regarding lithium battery assembly and maintenance.
I will share some useful professional advices on the following days.
Thanks you guys!
Pls visit our official sole website: http://www.rj-lithium.com
Hope it help!

Nice to see you here Mark.

If you are going to attempt to sell dumb lithium chargers, and battery packs with built in BMS then it wont!

If you can supply NEW not used, properly packaged LiFePO4 cells, at a good price with accurate capacity and accurate IR as well as decent shipping rates than it may well do. As long as you have cells that maximize capacity in a given space.

I got my cells from him

[Burgerman]

Are they good? And not bad threads etc? I get confused, many sellers! Where did those used cells come from that were supplied to a member here?


I want a set soon. Preferably the 100Ah ones or the 176Ah cells. But they are really 165 right?

I messed up the thread in one of them.
Yes they are great. I got 169 AH out of them

[wheelie junkie]

Exactly, I am saying that my extreme programming settings put way more strain on motors, controller and batteries than a stock setup. So your super soft settings should not cause any warranty or reliability problem. Quite the opposite.

Totally agree it shouldn't affect warranty but we both know that dealer/manufacturer will say any modifications will invalidate the warranty. If they saw my wheelie video they would probably claim it wasn't "normal" use and use that as an excuse not to warranty. Even if you are trying to modify to the spec it should of been possible to order. I'd rather have a chair that fits what I want and worry about warranty if it is ever needed. Consumer Rights Act covers almost what a warranty does anyway.

Next question is how can you check that the parkbrake is correctly set and adjusted?

Mark from RJ Energy, can you give me a price for 8 qty 3.2v 100AH https://www.rj-lithium.com/sale-1153043 ... -cars.html including shipping to the UK please.

[ex-Gooserider]

Normally there is not much, if any adjustment on the brakes - either they work or they don't...

Something that does make a BIG difference in how easy the chair is to move in free-wheel mode, and which isn't changeable by users is how the free-wheel mode works...

Some chairs have a lever on each motor that disengages the gearbox, and those will be easy to push as you are only driving the wheel axles and maybe one or two gears... The motors are completely disengaged.... Downside is that you have ZERO brake action, so if there is a slope you will probably roll...

Others do free-wheel by mechanically disengaging the brake, and those will be MUCH harder to move as you have to backdrive the gearbox, and spin the motors at the same speed they would have been running at if driving at the same speed.... Harder to move, harder to keep moving, but less likely to roll away on a slope...

Easiest way to tell which is to look at whether the free-wheel lever comes out of the gearbox or is on the brake end of the motor....

If you (or your carer's) were used to a chair with gearbox side free-wheel and then switch to one with brake side freewheel, you will think the brakes are stuck on / not releasing just by the amount of difference in how hard it is to push the chair....

Well I managed to fit a 75Ah LiFePO4 pack using 40x15Ah Headway cells configured as 8S5P, which my chair originally took 40Ah Lead bricks side by side like yours. So I'm sure you could fit 8x100Ah cells like these... https://www.lifepo4-batteries.com/sale- ... -cars.html

Steve

Yes, 3.2V100AH Works.

Pls visit our website for it.

We are Manufacturer, thanks to E-commerce, with Factory direct sell, really help save some money from buying distributors.

Hi You can consider us. I am sure our batteries will meet your full satisfactions.

Thanks.

[Burgerman]

No more links to your site, we get it. You sell lithium batteries and cells. I deleted 4 spam posts so far. And several more links...

How much for 8x100Ah cells including shipping to the UK please?

Thanks,

Steve

[Burgerman]

I suspect he is here mostly to drop as many spam links as possible.

I deleted a bunch of cooky cutter posts already.

[steves1977uk]

Hmm, you could be right BM! Don't get why they feel the need to spam though!

Steve

[wheelie junkie]

I don't know if it was spam but I contacted the company in the link who are RJ Energy, had really good service from Carl Wu and ordered 8 x 100AH cells for a cost of US$677 all in, 7 day shipping. PM your email address if you want Steve I'll introduce you or give you his if you prefer that.

[steves1977uk]

That's about £525 which isn't bad considering they last a lot longer than lead bricks! Might order some soon.

Steve

[Burgerman]

Spam?
Because while we might buy a few sets of 8 cells, the spam gives them link juice. Google sends them hundreds of hits and sales from now till indefinitely via search... So they want as many links from decent websites pointing to themselves as possible. As for advice and help, they dont tell us anything we dont already know better and some of those spam links were to stupid BMS boards... So they dont read here, and are just pushing their sales. Not that they may be bad, or a bad company. They seem pretty good. But this board is not here as an advertising marketing aid for their website.

Theres another registered now, from a random throw away email address and a vpn. memberlist.php?mode=viewprofile&u=4919
Same company... Similar name.

[wheelie junkie]

I followed the lifepo4-batteries. Com link to the cells that Steve posted, it is the same company as RJ lithium so they must have been tracking where traffic came from which lead back to here. Once they get in they will keep trying. I can't complain about the service, they've answered all my questions promptly, told me that it will be a tight fit and kept me informed of order status without being asked. I get the feeling that they are just proactive about selling thus use whatever they can to get contacts. Very different to your average disability dealer in the UK where you can wait weeks for a reply to an email.

[Burgerman]

I am not saying that they are not efficient or good to deal with. They may well be!

But they also claim to be a manufacturer. That may or may not be true. They all say that! In the end that doesent actually matter. But if I let every company that wants to drop endless links in the name of 'assistance' do so then this would be a spam forum!

[wheelie junkie]

Please keep banning them, no-one wants to have a screen full of junk. Your forum, your rules seems fair to me.

[Burgerman]

I ban a dozen spammers via Email, username, IP address daily. The forum would be overun otherwise. Often before they ever post a thing. There are forum spam databases of IPs, email adresses, and usernames on the net that people like me use to get rid of the manual, and bot entries and members. Some of it is automated and software based. The only problem is that now and again it bans whole ip blocks of trouble... That may be fake and belong to real users. So these get banned in the crossfire so to speak.

This one is a company that people here use, and may be a good and useful supplier. But all the posts so far were shallow, and basically "shop here"... And 6 or 7 that were all but identical in 3 to 5 mins on different threads. So rather obvious. But not banned. Just warned!

Heres an example of 4 or 5 blocked/banned/ etc over 6 hours! This goes on automatically or manually 24/7...

[LROBBINS]

Somehow you manage to rid this board of bots and spam, but outfits like Twitter with enormously more resources somehow can't, or at least take days to do so after a bad actor has already been identified. I wonder why (rhetorical question)?

[flagman1776]

A forum I admin gets SPAMMERS too. Nothing on the internet can be left unsupervised. They register in the middle of the night... I delete their SPAM & ban them every morning. I would allow a business a single post in the correct location IF it had real information to share. Some are pure click bait.
I never click on their links without Googling them first. Some don't go where they claim to.

[Burgerman]

Beats me how bots and spammers can beat several anti spam questions, and identify the anti spam image capture letters correctly, yet humans cant!

I think social media have a different issue. They can remove spam, when its obvious. They can manually review spam when its dubious. But many reviwers are slow to understand what actually is spam. I can spot it a mile off because I used to do the google ads thing... And I know what their objectives are. I also understand the google traffic value and what page rank and link power is/does to traffic.

The real issue they have though is the gov telling them to police the internet for 'hate speech'. Thats impossible. For e.g. I have read a lot of tommy robinson stuff. I saw the hatchet job the BBC tried to do to him for e.g.. I watched the unedited film where he showed via mobile phone footage what they tried to do to him. You should watch it, as its discusting. Typical criminally biased BBC. Likewise I saw how he was set up by the police/courts and prosected for telling the absolute truth only. And factually and evidently correct. And then put in a prison in a specific wing of dangerous muslims several times on purpose. And much more. The system systematically attacks him. For telling the truth. For e.g. about the muslim rape gangs. It appears that hate means anything that the liberal lefties dont like. Factual or otherwise.

So one mans truth is the governments 'hate speech'... So as a company like twitter or facebook etc who simply provide a blackboard or the thing to write on, they should NOT be trying to control what people are allowed to post. If the government dont like what INDIVIDUALS say, they should prosecute that individual. Not the blackboard owner. But to do this they will need to define what hate speech actually is. And why. And they cant.

For e.g. If its something that incites violence or causes mass disruption of society as described by mrs may recently, then the latest green save the planet global warming nazis should be prosecuted or banned from google, facebook, instagram, twitter etc too. But they are on the 'correct' side right? So who decides?

Sorry guys, Not very familiar with rules, but just really want to share something about lithium batteries that helps, and more links I promise.

[Burgerman]

Sorry guys, Not very familiar with rules, but just really want to share something about lithium batteries that helps, and more links I promise.

You mean NO more links unless very relevant to your reply I hope.

Well several people have asked questions, you might start by responding to those?

I will start with this one.
Why is it that when we measure MOST lithium prismatic cell capacity, very accurately, we seldom get the capacity claimed? Sometimes a little less, sometimes a lot less, depending on supplier.

We use computer controlled very accurate chargers and discharge capable devices that graph and measure results and display graphs on the PC screen. And we can control the end discharge voltage of each cell, and many charge and balance parameters very accurately. So where is the missing capacity? Or should I say, why do the chinese exadurate, when we can just measure this and see it is not true?

If you send me one cell, any capacity, I will test here accurately in controlled way with monitored temperature etc, so we can see the results!

Why don't you follow what other forums are doing.
They have a pinned section for each company. That way we can tell who's good and who's bad.

I go on OCUK forums a lot.
All the major companies have staff helping out people.
It would put another string in the bow.

RJ-Liithium Battery sticky thread? I think that's a great idea

[Burgerman]

We already have too many sticky threads. They are taking up the top half or more of most users phones or laptops. And that means 101 companies with commercial links which will never return or help anyone. WE can link to other companies if and when its useful or helpful. They can help out if they want, and we already see he has a link to anyone interested in his profile, and already in 4 places on here. And it can be added to the where to find stuff pinned thread already!

[wheelie junkie]

The Ducati forum I set up had a no commercial advertising policy, if you wanted to advertise a business you contributed to the hosting and software costs (used vbulletin which you pay for). Almost all the north dealers helped out by contributing, didn't cost much but they were seen to support and got a lot of goodwill.

You could add a supplier sub forum but is just another one to police, who decides if a supplier is reputable?, if you allow reviews or recommendations who decides if they are genuine? Way too much work with the potential that the company advertising isn't genuine and could scam users. There is no need to take that risk when the forum works OK as is although I admit that it can take some digging looking for suppliers but that is because there is so much useful information.

[steves1977uk]

Well it seems the 100Ah cells are out of stock at the moment, but they do offer the 120Ah ones for the same price.

Steve

[wheelie junkie]

I must have the last of their stock on the way. Wish that the 120AH would fit but I didn't get the same price offer!
