I know how they burn, had a 5000 mah voltz pack burn after a crash, what im sayn is you can see what caused it to burn. did the charger or the battery catch fire first? it was mostly in fun anyway.

BTW, do those hard cased lipos the car truck guys use burst into flames? I know weight is our concern but if a case would stop or slow a fire I'd have to think about it.[/quote]

The hard cases for those lipos are only to protect the cells from being damaged/punctured while racing the car. It does not afford extra protection from simultaneous combustion due to mishandling, over charging, etc.

Cam would of been nice
Can't stop thinking what the hell went wrong here
You have good working packs and balance charging. And I thought the TP820 was a high quality charger at least at one time it was. I guess the bottom line is....nothing is safe unless you make it safe

Better question is....how many of you that read this post still charging and walking away in an unsafe area?

Keep in mind that almost all chargers these days are computer based. They rely on software written by developers to function. It's entirely possible that the software can contain bugs that can cause the software to not function as intended. Sometimes those errors are harmless and other times they can be catastrophic.

You could install a surveillance system with dvr. And dedicate 1 camera to your charger!!! That way you can look back on the dvr and see exactly what went wrong!!!

Most people are now installing them for home security anyway.

It sounds like the packs go up so fast. If I was standing there watching them I don't think I be able to prevent a fire. I am just going to charge out side the home.

If you choose to get a Class D fire extinguisher, know that they are not all the same. They have different agents for different types of metal/chemical fires. For LiPo fires you want one with a copper extinguishing agent not the cheaper sodium chloride extinguishers.

Here is a link to the type you want. http://www.safetyemporium.com/ILPI_...etail.htm?09592

These kinds of threads are why I do 95% of my charging at the field. I rather burn the crappy tables at the field then my house or garage. If I do charge at home, it's outside on the patio.

basically the hardcase is for protecting from puncture, now with that having been said a puncture like one might sustain in a crash) can cause a lipo to go off so if a heli is goign to go down i think i would feel a little more comfrtable with the added armor protection of a plastic case. one caveat though is the hard case will add some weight but i doubt it would be a problem for flight that is just my .02

Remember that the hard-case design will add to the overall dimensions of the packs needed.
This may be a problem when trying to fit them into most models as they are designed to fit packs that are not in hard-type cases.

I wonder about commercial products that use Li-ion. I have several such as a chain saw, shrub trimmer and edger that run on batteries. These are 40 volt 2.5Ah Li-ion packs.

I think about the hereafter. I go somewhere to get something, then wonder what I'm here after ?

I'm sure what happened to you will help at least some of us to avoid this. All I can add to this is to say ALL batteries are individuals and no two are exactly alike. Nor any two cells in the same pack. Yes a fuse will help protect from a main short but a bad cell is not always a main short. If a manufacturer is responsible they will test their batteries and put in a safety margin as to rate and speed of charge. For most chemical reactions slower is safer.

I know how Icarus felt

$875 for the fire extinguisher plus another $40 for ground shipment.

Yeah, I am going to run right out and buy one of those.
