what happens when you combine red necks with a lithium battery?

now you know why batteries can be dangerous if not used properly

pretty cool.
Now you know what I have to live with here in GA

GA? try FL!

-I knew I was a redneck soon as I put a bucket in place of the toilet.

Im from LA . . . that state held me back for most of my life . . .

I think I will be very careful with the LiPos I ordered from bidproduct.com a few days ago...

lipo isnt the same as lithium ion?

From Wikipedia:

Lithium-ion polymer batteries, or more commonly lithium polymer batteries (abbreviated Li-poly or LiPo) are rechargeable batteries which have technologically evolved from lithium-ion batteries. Ultimately, the lithium-salt electrolyte is not held in an organic solvent as in the lithium-ion design, but in a solid polymer composite such as polyacrylonitrile. There are many advantages of this design over the classic lithium-ion design, including the fact that the solid polymer electrolyte is not flammable (unlike the organic solvent that the Li-ion cell uses). Lithium-ion polymer batteries started appearing in consumer electronics around 1996.

At least they say LiPos aren't flammable

__________

Edit:

Overcharging a Li-poly battery will likely result in explosion and/or fire. During discharge on load, the load has to be removed as soon as the voltage drops below approximately 3.0 V per cell (used in a series combination), or else the battery will subsequently no longer accept a charge.

the rule of thumb I use:

lithium ion holds a higher charge

lithium polymer has a higher discharge rate

I prefer Lithium ion because I generally never need 30A continuous with Li-po. . .

PLS reply and give my ideas on why i cant see the video or if you also cant see the video.

Admin · « **Reply #13 on:** July 08, 2007, 07:00:50 AM »

Well for one you are trying to embed a google video using the youtube embed script

I dont currently support embedding google videos. You will have to just link it. Its one of the thousand things on my to-do list . . .

Sorry typing error haven't been paying much attention to my spelling.

What did they do to make it explode?

megaman935 · « **Reply #20 on:** July 09, 2007, 07:25:46 PM »

Overcharging..............................................BOOM..............................................

robotvisionary · « **Reply #21 on:** July 09, 2007, 10:00:29 PM »

They use a transformer to replay what would happend afters days or even weeks or month of charging constantly
