Lipo Safe Proto

[ReddyWatts]

A person might want to think about keeping the lipo batteries in separate containers or bags. If one goes, they all might go!

From what I have read the ABC or BC class extinguishers should work on a lipo (class C-electrical) fire???

[Doug Smock]

So what kind of fire extinguisher does it take to put out a lipo fire? A regular A, B, C extinguisher will not work?

That is good information.

Reddy,
I looked real quick and can't find the information. As I recall it was a "K" rated extinguisher that was recommended. Or, good old sand.

Class K is for industrial "K"itchen fires. It is expensive because it leaves no residue. Uses halotron gas.

That may be a good idea I don't know.
Some of the LiPo vids I have seen where people have shorted cells or overcharged cells to the point of failure, ( Fire) there were single cells that survived a fire within the pack.
I'm still on the fence on this one.

WOW! that is a lot of information. I just dont understand why we would need a K extinguisher on a lipo fire? ABC is supposed to extinguish all fires and sand will work. They are just not clean methods. Leaves a big mess.

Yes I understand.
I am going to concentrate on "just saying no" to LiPo fires,and just be as safe as one can be.
My son and I agreed this weekend that we will have no conversations while we are putting cells in a boat or on the chargers. It is just too easy to make a really stupid mistake that could possibly be life altering.
I think these cells are actually pretty safe if we just use common sense. I will continue to keep them in a safe place, not push them,( run2p setups ) and carry that bucket of sand. LOL
On the other side. I have a friend that flies and has for years. He has loose cells in his garage, basement, mini van, and in his office. He has never had a problem.
I just don't see myself going there.
If you do find more information about extinguishers, I would be interested in knowing.
Thanks,
Doug

Better let your son carry the bucket of sand! lol!!!

Final product

Well I took delivery of the box today. I am quite pleased with it. I put it on the scale and it's 22 pounds even. The pictures speak for them selves. The next one is still under construction and is spoken for. I really don't plan any more unless some one is interested. They are not very cheap. They take about 7 hours to complete.
