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 Год назад

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.

Be careful of eBay's new dispute policy. I purchased fuses for my fluke multimeter the seller sent me the wrong item.

You can no longer call customer service.

@cookiemonsterrey Год назад

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 Год назад

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.

@martywollner4128 2 года назад

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 RU-vid 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 Год назад

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 Год назад

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 Год назад

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 : ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-uXO_Xb8fvbc.html

@martywollner4128 Год назад

@@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 RU-vid. 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.

@myfastcars Год назад

How much did you have to pay for that pallet of batteries (cost per battery) ? How many are totally bad? Can you do a repair/autopsy of a bad battery? Why are the state of health/battery monitors failing? Lots of questions but, I bet other people would like the answers too.

@RileyTheMonster299 2 года назад

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..

@mogeking56 Год назад

Reason they catch on fire 🔥 is that the battery 🔋 pack is so large and it contains a lot of heat, heat that builds up to a critical level and all it takes is one ☝️ critical defect in the battery pack or if it hits that critical temperature 🤒 of combustibility then you have your fire 🔥. Gentlemen these are not Tesla vehicles 🚗 with cooling coils they are straight battery 🔋 packs they get hot very hot when you ride and when you stop riding and immediately start charging your batteries they get even hotter that’s when you burn down your house, she shed, apartment. Don’t be stupid if you want speed buy a motorcycle 🏍️ not an ebike, ebikes are for older people who just want a little exercise without having to bike their old legs 🦵 up a hell.

@spocksvulcanbrain Год назад

You're assuming quite a lot by saying the display is the problem. Consider that in most displays like this (this type of application) the DISPLAY goes through a diagnostic where all the lights light up, before then the system shows the charge of the battery. This is done to let the user know that the display and system are working correctly. Otherwise, one wouldn't know if the system or BMS were bad or if the batteries were low on charge or dead if it just showed the current level of charge without showing that all the indicator lights work. .... rookie mistake in understanding.

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.

those led lights indicator I replace it by volt meter and also its bms.

@DallasAya 2 года назад

It's an ON light. Means the battery is ON. Has nothing to do with the level. Probably starts flashing when it gots low. I can build a new battery for $95. 48 volt 15 Ah Model3 2170's all day long. Why by rubbish?

@fouroakfarm 2 года назад

$95 for these seems like a great deal. Could you give me more details on how to DIY for even less? (cells, BMS, source/supply) Thanks

Hey! I have the same batteries at home. All of them start with 4 lights and then go to the mode with one light. It's just badly designed but I don't think that was the problem with the batteries. It's an older design though, so that would more likely be the reason why they were sold off.

@sthlng2180 Год назад

Its not bad design, theres no reason for all 4 leds to drain power, no matter how little power they consume

@jacobhn2 Год назад

@@sthlng2180 the one light led may show that the output is on of the battery, you can turn the battery on and off on the push button hold it down for 5sec maybe . My battery have a key to turn on and off

It"s a pity in Europe we cannot buy your batteries . . .

Yeah the indicators might be for a 60v battery

@rahmanr112 2 года назад

Is it better to buy 2 of these or should I buy one new 12v 100ah lithium battery from Amazon... I need my PC to run, its total 600 watts. I already have a inverter that compatible with 12v-48v.

@ChrisP978 2 года назад

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.

@@ChrisP978 Thanks I ended up ordering the ECO-WORTHY 12V 100AH LiFePO4 had a $20 discount which I can also charge using my 4 solar panels in parallel. Are 8 gauge wires sufficient for 50A?

@ChrisP978 2 года назад

@@rahmanr112 8 gauge is adequate if distance to inverter is short (< 4 feet).

do you or anyone have link for the type of connector needed to build my own connector to charge it? and do you have a video for it as well when you make it and test it?

@klepperkamarad 2 года назад

Can you list the type of connectors needed to go from these batteries to a controller?

@ianmangham4570 2 года назад

Depends what connector is on the controller

@klepperkamarad 2 года назад

@@ianmangham4570 You have misunderstood the question... For those 48V batteries, the output requires a linear 4-spade connector and for the 36V batteries, those need a circular, 5-pin connector; I need those connectors identified.
