How should we dealing with Li-ion Battery for flight safty?

Posted by Jiro Hattori on January 17, 2013 at 1:55pm

As you know the Boeing 787 has been grounded by caught fire on the Li-ion battery.

It looks like Japanese battery may have some issues on this incident:-(

You might reminded some laptop PCs caught fire by its Li-ion battery, few years before.

It is ironic to the restriction of Li-ion batteries for carry on baggage and air cargo.

Our copters will not fly without high power density Li-Po.

How do you treat your Li-Po battery and deposit after some failure ?

    Its very funny. You know why? Because if it was an actual concern you wouldn't fly. By putting one in the air you are risking a fire every single time, we all CRASH. We know what happens but we still risk it with every flight. I think the question is hilarious. I put them in the air everyday. How do i treat my lipo? Lets see, i strap it to a toy and fly around at 300 feet. That in itself is irresponsible. Oh but at home i put it in an ammo can, because it's not safe on the ground.

    I have seen a few videos of lipo fires on model aircrafts, no laughing matter to me. I wonder just how effective would it be to monitor battery temperature?

    T    hat's a link to a cool flic about the build and design of the 787 on netflix.

    By my engineering standards, if the strap ain't melted on the box, we're good to go. But...then again I was a diesel engineer for the U.S. Navy. Post a fire watch on it with a Co2 bottle and we're good to go. We did things different.

    It has more to do with the way information travels around large corporations like Boeing than any technical problem.

    Gary, It could be a problem not encountered before, pressure cycling many times. Actually the 787's carbon fuse is rated higher than traditional aluminum construction. Normal jets pressurize to 8000 ft. and the 787 goes to 6000 ft. Better for the passengers.

    Having said that, I would bet it is the first jet to use Li for battery back up. Most Lipos don't pressure cycle all as much as a Japanese airliner.

    You could be on to something. I know some scientists working on next gen Li cells(where I work), and I will definitely run this by him. I hate to see Boeing hurt like this. This will be tested in the lab for sure if it hasn't been all ready.

    Not jumping just speculating, anxiously await actual data.

    That's what I'm talking about James. Caring for your things. Going above and beyond. Bravo! I also like to poke air holes into them so they can breathe. Nobody likes to suffocate.

    I prefer to keep mine next to my open fireplace. Wouldn't want them getting cold.

    I store mine in a pillow case filled with straw under my kids crib mattress. That's good right?
