Here is what is wrong with all these eBike Batteries

Maybe there is nothing wrong with the batteries at all but are programmed for one LED to stay on to show that they are on and operational ready.

[@irvan36mm]

I was thinking the same. I think that it is showing the charge level after you first turn it on, then goes to one light to indicate that it is on. Push the button again to see how much charge you have left & hold the button to turn off.

These are the batteries from Aventon pace 500 and 350 bikes. There is nothing wrong with the light. The green light just shows when its on. To check the power level you just push the button. You hold the button to turn it off. But I don't know why they have been rejected.

[@jansmit4628]

I think you are right. At switching on, the LEDs indicate that they are working, regardless on the battery state as long as it is not completely empty. The display on the handle bar will show the actual state during your cycling tour. When disconnected from the bike you can request the battery state by switching it on, the press the button for a short time so it does not switch off and the LEDs will roughly indicate the 1/4, 2/4, 3/4 or 4/4 state for a view seconds. So nothing wrong with them, just an obsolete or redundant batch of batteries sold for scrap.

[@threeMetreJim]

The bms low cut off voltage seems very low for a 13s battery. Should be around 36v. Makes me wonder if the bms is working correctly, and if it cuts the charge at the correct voltage (54.6 v or just below).

[@RileyTheMonster299]

There's nothing wrong with them they're just not on the bike so they're going into a rest mode that's what it looks like to me. I don't think there's anything wrong with the indicator I think that's just what they do when they're not on a bike that's like a rest mode showing their ready but maybe not in use. That would explain why they dinged up one does the same thing the one heavily used one does the exact same thing as the brand-new looking..

Jehu, these are Aventon Pace 500 and 350 batteries. The fuel gauge displayed is normal operation for those batteries. The single light tells you it is on. To see the level tap the fuel gauge button once. Hold to turn off. These are made with Chinese cells.

Hello ,when u gonna do the 12 volt lifepo4 60 cell pack build. I've already bought 8 of them

[@martywollner4128]

I hope you have fire protection for your family and pets. Just one bad cell in one of those unit could set the whole lot off. The fire would spread from cell to cell and then ignite other units nearby. If you haven't watched any KZbin videos of this, I strongly suggest you do. Mixing units from different manufacturers and using non-matched chargers and cables is the fastest way to cause a thermal overload. Once the fire starts it cannot be extinguished with water. And BTW, water alone can cause them to catch fire, especially salt water.

[@JoesWebPresence]

Easily scared people without the necessary info may think so, but these are li-ion 18650's. Unless you are seriously abusing them they are extremely safe, unlike li-po sachets and cheap Chinese proprietary cells found in phones and vapes. The youtube videos are hype, and the numbers don't bare out the fears they encourage. Working with liquid fueled or mains electricity machines is way more likely to cause fires, along with many other hazards and fatalities. Battery packs such as these are extremely safe in proper use, and the machines they power are therefore much safer than their petrol driven alternatives. Short of running one of these over with a truck, you'd be very hard pushed to get one to catch fire, whereas a mere spark landing three feet away will do it for a fuel can. I'd re-assess these dangers if I were you. Only the cheapest lithium batteries are prone to catching fire, and powering vehicles with packs such as these is safer than any other method of transportation, maybe with the exception of sail.

That fire is vicious, and those suckers will pop like incendiary M80s for hours in larger batteries - all you can do is contain the fire and wait it out. Those numbers you speak of... where are they exactly?

[@JoesWebPresence]

I didn't say it never happens @@thom1218 just that it's WAY less likely than say, petrol fumes igniting. The HSE has some stats confirming this, but ask your local fire brigade how many lithium battery fires they've had to deal with. As a supplemental, ask if the batteries were made in China. They will have been. Properly constructed Li-ion cells are far safer than any flammable liquid, for what I thought would have been obvious reasons. Avoid cheap Chinese ripoffs and you'll be fine.

[@Ken_1971]

A good safety advice can NEVER be wrong so you did a very good comment here ! Don´t forget to install smoke detectors on the ceiling in that room which react very quick on any smoke with a super loud beep noise ! In case of a fire ( which always can occur when having so many electronic parts in storage in that room ) there should be the knowledge how intense the fire can get and the knowledge that there is no way to extinguish the fire ! Lithium-Ion cells will burn with up to 1000°Celsius. The only possible solution is to throw burning batteries ( do not try to carry those burning battery packs by hand, just use a big showel ) into a big barrel which is completely filled with water to keep the burning battery cells under control for several days. May be you got a big swimming pool or a pond close to the storage building where you can throw the burning cells into. If not i would put several water filled barrels into different parts of that storage room to have quick acces to them in case of a fire. What also can help to prevent damage to the building is a fire blanket like this one : kzbin.info/www/bejne/q4mykIuYbcupmMU

[@martywollner4128]

@@Ken_1971 Yes, thank you, Ken. That Joe web-guy is either a Chinese bot or a moron because that room in the video was the most dangerous place on KZbin. The video guy obviously made no attempts to match original cabling and chargers, which is the fastest way to cause thermal overload. Once these devices get old, they are all ticking time-bombs. And I am sure that many of them are damaged as well. But, ya see what happens when we try to help? I predict battery fires to be a great problem especially with EVs... I predict they will be involved in so may fires that they won't be allowed in tunnels or for school buses, when the body counts significantly rise. I also predict a huge problem with fires in recycling centers and in trash dumps. I also predict that arsonists will start shooting guns at larger battery devices when they learn how easily they can be ignited. All of these fires create toxic pollutants which by far outweigh the use of petrol vs. EVs. EVs are just another way to control the population.

When weight isn't a concern you'll get more cycles out of a LifePO4 battery vs Li Ion. Calculate the total Wh capacity you need to cover your use case run time. Only downside to 12V is that you need thicker cabling, 600W is 50A at 12V. You could also use 2 12V batteries in series to get 24V.

often there is a chip in the BMS that counts down - for planned obsolescence. Try locating it and reseting it by pulling a reset pin down to 0 volts for a while, will give you some year/s before having to reset again.

Sounds like you may be on to something there. Some batteries for like BIOMED equipment come with guidelines from the manufacturer that, in some cases, count just five complete discharges as end-of-life. BIOMED standards are a very high level for obvious reasons. Tools manufacturers have between 500 and 1000 complete discharges as end-of-life mark.

You are thinking of an Apple device. I have seen a chip for charge cycle count yet to disable the battery pack?

Sounds like a 52v charger and wouldn't be compatible. 48v charges at around 54v

[@joshualoman910]

Where can I buy some of these ebike batteries?

[@beebeejoo]

Are you going to restock these on your store any time soon?

[@Thomas-yr9ln]

Do they have ebikes in Mexico where you come from ?

[@jehugarcia]

I haven’t been to Mexico in 40 years

[@edivollgas719]

think you should get in the case and measure the cell voltages . if 48v they will be 13sxp ... so check the 13voltage values and compare........ might be the bms is signaling its beyond balance capabilities because of single bad cells ...... or bms is bad ....

[@carlosbanegas6616]

What could be happening also is that l.e.d. are low voltage so when battery is been power up the l.e.d. get a surge as battery powers up,voltage drops and display goes shows actual charge, mind you now just my 2 cents AM not an electrical engineer.

[@Home_made_ch]

Ar not you sending them to uk?

[@jehugarcia]

No

Hi I got ebike 48v what charger do I need it'd same battery as this I thing I got wrong charger it goes green then dim then green, is it charging?

[@rmack3481]

Where did you get the small meter?

[@dramspringfeald]

If I remember, remember all those Ebike/scooter rental companies that collapsed?

[@Cesar-cm4if]

I do! And I think everyone should also remember to wear NTA helmets like xnito or bern hudson while ebiking or riding an escooter, cpsc helmets don't protect you on these class 3 e vehicles

Just got my delta pro it’s awesome. Charged it a bit from my scooter that has 4 of the 36v aluminum scooter batteries. Currently charging on solar outside. 👍

[@glenluyckx12]

Hi, What kind of charger is that?

[@PolskiDangles]

Note: My R3's (I bought 3 here) work fine. I just have to press the button each time I start my ebike. The ebike with KT controller I have to press controller "ON" button at same time as the power pack button. Good thing is that the BMS shuts off and saves your battery. 1 green dot = BMS on. Hold button to turn off. --- Still need discharge connector for my R4 (SYR002). Is anyone creating those? Home-made ideas?

[@monad_tcp]

Seems like a stupid software thing. Someone decided to save led power or a bug in programming.

[@davidwood7879]

what are the dimensions of the battery their are like 3 sizes

[@benheynen2705]

Hey what do you think has happened here? I bought 2 fastwheel f0 batteries and 2 Xiaomi fold up bicycles when I lived in china and used them a few times and left them for a few years now. All of them are dead and this is what I often find with packs that have been left. Seems to be the "mystery of batteries" I have stripped one of the f0 batteries and found they are 2200ma Samsung cells so they should be good quality. Found using the IMAX charger that its a 10S2P configuration and that 2 parallel cells are open circuit and the rest all have like 0.2V but do charge up one at a time showing a good capacity when charging. Still have yet to see if they hold a charge but just wonder what caused it to both go open circuit and then all the other cells to almost fully discharge. You think it will come back?

[@MrKevin920]

Once lithium batteries go below a certain voltage the batteries are no good anymore

[@hi-tech-guy-1823]

It may be A Software Firmware Issue why the LED indicators is miss behaving (or in a Undocumented Stage)

[@MrSillyotter]

Do you still have any of those batteries?

[@sams5803]

Pumping out good content all the time!

[@theiamoon6332]

Sir I dont have any background when it comes to batteries/electricity but I really want to build an ebike so I can get to my job back and forth which is 15km in total. I bought a 48v 20AH 13S 18650 lithium hailong battery from aliexpress. Any suggestion which motor and controller should I buy? Any reply is very much appreciated.

[@wande.r]

Bafang mid mounted diy ebike is an option im considering..... How did you get on?

[@llooe8532]

Any deals on a 24v ebike battery

[@jehugarcia]

I don’t have any 24v ebike packs, Never even seen one yet

[@jr-ft8ht]

Hey just hi I was wondering if you can sale me 2 and the chargers 🔌
