Here is what is wrong with all these eBike Batteries

********************************************************************************
FAQ:
8) Why not use Supercapacitors?
A. Batteries work better at this time, caps are rare and expensive devices that are very good at doing things not needed for storage systems typically.

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.

Send one to Big Clive! He’ll figure out what’s wrong with the battery meter part. :)

Man, I bought 8 and this is driving me crazy for past 2 days. Almost had to email support but just saw this video.

[JimNichols]

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.

One thing to note if you're buying these to harvest cells is that they are extremely hard to get into, the metal case is tight around the cells.

I wish we had a store like your in Europe.. if some of the viewers know the good source to buy things like this in Europe - please reply. Thank you.

I have the same batterie on my bike. Once the batterie was broken and I opened it to repair it. The current limiting resistors on the led indicators are getting really hot and tend to fail. Maybe this can help you to get what happened to them. By the way a solder joint was broken - an easy fix. Greetz

Be careful of eBay's new dispute policy. I purchased fuses for my fluke multimeter the seller sent me the wrong item. Seller would not respond to my messages. eBay's robo customer service said the item was delivered they know this through tracking so you did receive your item, case closed. You can no longer call customer service.

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.

[hi-cbattery]

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.

There is no problem with that LED. All is ok. It says IM ON. When u wake up indicator it shown SOC and then just showing status.

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 YouTube 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.

[RileyTheMonster]

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..

[ebb]

don't think there is anything wrong with the display, just does not show state of charge all the time but shows it is ON...

[helderu]

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.

[AegisPupus]

I would open one up to see if the meter is set, with a jumper, to measure the wrong battery voltage. If they make multiple voltage, the display is likely the same with different settings.

[VintageFilmChannel]

Thanks for the video! Great to meet you at octo yesterday!

[AerialAcesRC]

What is a discounted price? Also, Where can we locate these, or similar, if not larger packs? Thank you for this, as we have already purchased a few imported 36v lipos, and have been VERY pleased, accept we did think and act as if the little charge indicator LEDs are a VERY BASIC way of telling if its storage/80%/100% more or less, so this def. helped verify my thoughts on this particular yet common issue!

[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).

[niteshpatel]

I am looking for the discharge connector/plug for this battery.
