Just a reminder guys on how fast you can cause a fire. Sunday had a friend pick my up a 550 mah battery on his way to my house, was in a hurry getting everything ready to go to the field.. took the lipo, and put the charge cord on it, realized the other battery wasnt quite finished charging so had to wait for that to finish. Sat the lipo down on the bench and walked away. 30 seconds later my buddy is hollaring that something is smoking.. went in to find that the charge leads had touched when I sat it down. although it was only a 1 cell 550.. it was puffed and hotter then hell and melting wires all over.. just a reminder.. BE CAREFUL guys.. only takes a second to get careless and ruin your day. luckilly all the damage was a melted wire, but this could have easilly been a lot worse.. Im usually really good about putting everything in the charge bag, and being careful but just that quick.. shyt happens..

Enjoy the holidays..

Yes. Care is needed. My main rule is that I never charge at home. I charge at the flying flied.

another rule - the very LAST thing you plug into anything (charger, aircraft ect..) is the battery. It's also the very first thing you unplug. GOLDEN BATTERY RULE!

I normally do that... it was a small battery, and again.. IN A HURRY! I think that last part is what did it.. just notpaying attention..

I just blew up my first battery in a crash (5000 mAh, 6S) this weekend.

It didn't flame, it didn't torch my heli (pack came off and was smoking in the canopy), didn't set the field on fire (although I was ready with my A/B/C fire extinguisher!).

It did create a smoke plume certainly visible from space, and it smelled really, really bad and was most assuredly highly caustic. Everything it was near also smelled bad for a while.

It was NASTY, and you do not want this happening in your house, even if the house doesn't burn down.

oops, bounced it!

I am glad all worked out for the OP and nothing serious happened.It is a reminder for all to be safe.and batts should always be treated with respect and handled safely

But before this turns into a "lipos are like C4 "thread, just a little reminder that ANY battery can start a fire if its directly shorted

I have along, in the truck bed tool box, a plastic container with lid filled with salt water to dispose of bad lipo at the field. Any batt. that taco'd or getting warmer to the touch gets immediate salt bath. That way, I don't have to sit around waiting for it go up in smoke or worry about the batt. catching fire on the way home.

true! I shorted a 4 cell 2400MaH NiCD pack and nearly caught the wires on fire! All the insulation burned off and the copper was glowing bright red, like a toaster.

jschenck, sounds like you learned from experience as well? Definately a fun hobby as long as all the safe gaurds are kept in the front of your head at all times. Definately gave me a reminder this weekend, thats for sure. Funny, went to charge batteries last night and the first thing I thought about was the "Golden battery rule" LOL

yep, happened in a flash too! I couldn't even unplug it because the wires had melted and were directly shorting to each other. The difference is the NiCD pack itself was not likely to go thermal - a lipo would have smoked for sure.
