Don't blame the technology. Blame the poor manufacturing process and the
lack of quality control so rampant in China. Remember the Chinese drywall
that was shipped to Florida and emitted toxic gasses? Would you tell people
not to use drywall in their homes? Remember the Chinese pet food that

Just a quick note to affirm the need for caution around Lithium-Ion
battery packs.
Today I was charging a new 12 volt Li-Io battery pack. Fist time being
charged. I was using a specialized automatic Li-Io charger.
Nonetheless, the battery pack exploded with an incredible force, blowing
One thing available and recommended are fireproof/resistant envelopes to
put LI-Io batteries into while charging. Maybe good practice it to
charge them outside at least the first few times.
Good to hear that you were not injured.

Have to admit, outside of actually combat, that was the scariest thing
I've ever experienced. The battery was a generic, Chinese manufactured,
lithium-Ion pack made up of 3 main, but unmarked, cells, wrapped in a
fairly tough flexible, plastic wrap. A little forensics leads me to

I said 12 volt, but it was actually 11.1 volt. I use this type for the
KX3, Quad-copters and driving computerized telescopes. I'm not familiar
with LiFe. I'll have to look into them. I had no idea they could be so
volatile! If I did, I sure has heck wouldn't have been sitting right in

All Li-Ion packs are not created equal. Charging rates depend upon
capacity, and proper Li-Ion packs have built-in protection modules.

Which part? That my shop is a machine shop - or that Li-Io batteries
could potentially kill you?
Sorry, but I find this kinda hard to digest.

Any chemists on-board? Curious as to what the exact chemical process is
that causes such a powerful state change. Hard to believe that something
so dangerous and volatile is inside so many things we carry around in
our pockets.
I guess my mistake was getting a pack that did not have any sort

That's the part lots of people here don't seem to understand. There is
inherent jeopardy in having lots of stored energy in a small volume,
coupled with a low enough internal resistance that allows very high
current to flow in either direction ... both of which are the case for
Li-ion
