At the begining I was afraid to even move my motorcycle cos I had read liteon battery can get fire and explote but later I read that the lifepo4 batteries are very stable regarding this, I was hoping that the explode part were less probable with lifepo4.e-beach wrote: it might also be a fire danger. If you charge it again, be sure to put it in a place that won't be a problem if it catches fire. Keep an eye on it as you charge it in case something bad happens. Do this every time you charge it.
How can I seal this holes? I'll apreciate some natural advices or not to complicate glue because I live in cuba and here we have very limited things in shops.e-beach wrote:
The holes in the cells also is a problem. Yes seal the batteries again. If any moisture got into the cells then it will degrade the cells further.
I'm sure the bms are broken, so I'll have to buy a BMS and the battery charger.e-beach wrote:
I am surprise the BMS didn't stop that 109v charge with over voltage protection. It is possible that the BMS is also now burned and not working right. The only way you will know if the BMS is working is to put the proper voltage charger to the battery pack and watch what happens.
For you pack to be properly charged it needs 58.4v from your charger. Each cell should be at 3.65v fully charged. (16 cells x 3.65v = 58.4v)The voltage
es you listed show that the cell voltages are low.
First you need a proper charger that works. Or you could try to charge the cells individually to 3.65v if you have a charger that can do that.
Only 110v AC, is the operational voltage of the charger and the standard here in Cuba.e-beach wrote:
How many volts was going into the 109v charger 110v ac or 220v ac?
First seal the holes in the battery as fast as you can. LiFePO4 is less volatile then other lithium batteries, but it is still a lithium battery and can catch fire. I run LiFePO4 for the same reason you do. It is a very stable chemistry as lithium batteries go. But, you have punctured your cells which should never be done with lithium batteries. Do your best to find an adhesive that will stick to the aluminum outer part of the cells and stay adhered if the batteries get hot. Pinch the foil closed and apply the adhesive to keep the foil sealed and air tight. No air should get into the cells.avago wrote:At the begining I was afraid to even move my motorcycle cos I had read liteon battery can get fire and explote but later I read that the lifepo4 batteries are very stable regarding this, I was hoping that the explode part were less probable with lifepo4.
Then that charger is not of use for your battery unless it can be adjusted to 58.4v dc on the output.Only 110v AC, is the operational voltage of the charger and the standard here in Cuba.
eBay USA is because the products are in USA, but every one knows those batteries are from China.999zip999 wrote:Before you buy a battery please give us a link so we could help evaluate the battery before you buy. eBay usa whats that ? Please include the controller and motor you will be using.
If you read the thread (which is a year and a half old), you'll see that he already knows what happened to the batteries and why (even in the first post), and he already bought a new LiFePO4 battery, though he was still looking for a quality charger for it the last time he posted.google translate wrote:Hello friend, I write to you in Spanish because you were Cuban, you killed your batteries when using the charger for acid lead batteries, the lithium batteries can only be charged with chargers for that purpose, and those batteries do not work. Unfortunately you will have to buy another package. I recommend lifepo4 which are the most durable but a little heavier.
