Hey all! Well, I've read about this happening and seen videos and such but I never would've thought it would happen to me... I definitely learned something yesterday.

Here's what happened:

The day began by charging up a few packs for a nice day of flying with a buddy of mine. While charging one of my 6s 5000 packs got over charged all the way to 27v. The charger (TP820) didn't **** off like its supposed to at 4.21 max. I found out that this is a common problem for that charger and they've just released a firmware update to correct it. After noticing what had happened, I freaked out. The pack was HOT! I was scared of the thing. I knew i had to get some juice out of it but had no idea how. the charger wouldnt discharge it because the voltage was too high. Go figure huh! After some help from a few of you folks on here I decided to let it cool down and run the pack in the heli to get it down to a safe voltage. I let it cool down and then ran it for about 3mins on the ground at 0 pitch. Thankfully that worked. I got it down to 4.17 in each cell but they were a little off on balance. Because of that, I wanted to try to cycle it on the charger to see how it reacted. I discharged fine and then I proceeded to charge it back up. It took a long time. More than usual but it seemed to be fine. The cells were still off a little bit but not too much (.03 or so). I thought this would be ok to still fly it. I guess I was wrong...

I went out to the feild and wanted to fly that pack first to just cruise around and such to get comfortable. Well, taking it nice and easy went right out the window when I had gained an audience. I flew it pretty hard. No smack but some big air, power moves...

The flight went fine. I (for some reason) cut the flight a little short and brought it in to land. It was a good flight and I was happy of the show I put on. Well, as soon as I landed I walked over to a buddy to give him a "Hell yea, that was sweet" but I heard a hissing sound coming from the heli about 20ft away. I said "Hold on a sec, what is that sound" and we started to walk over to it. We got about 10ft away when it blew up in smoke. We all freaked out. I ran over to it and now it was in flames. I was trying (dispite) the danger of the fire) to pull the tray out of the heli. I tried and tried and couldn't get it out because both batteries swelled up inside the frame. After picking up the flaming heli and shaking the sh*t out of it, I was able to get the last burning pack out the back of the frame. Once it was out I threw the heli. I was soooo pissed. We then just watched the show in shock at what had just happened. One pack was gone in flames and the other was a balloon. We knew it would go too at any moment...

After the first pack went out, we checked over the heli to to what extent the damage was. It doesn't look too bad. Some of the wires that ran through the frame are burnt. The frame is burnt in some spots. motor, esc, beastx, ans most everything is ok. There is a lot of smoke damage. I'm just now about to tear the heli apart to see what needs to be replaced...

What if this would've happened in the air? What made me land before my timer was going off? I NEVER do that! I always fly till the end. We kept saying how much worse it could've been. It was definitely an experience to learn from.

THESE LIPO PACKS ARE NO JOKE!

Take caution! Always charge safely. If a pack is damaged or anything don't use it. Bad things will happen if your not careful and aware of every possibility. We agreed that from now on we will have a small fire extinguisher with us. This was a very scary situation that I hope none of you will ever encounter.

Here are a couple pics of the damage. Ill put up a few more when I get it torn apart.

Sorry to hear that. The lipo packs are no joke,I had one go up in flames on my craftsman rolling cart where I was charging,just a 3cell for my 450 at the time. Went in the house to get something,came back out not even 2 minutes later,one cell was bad,the charger was beeping like crazy and my garage was filled with smoke,opened the garage door,u plugged the charger and battery and took it outside. Thank God the part I was charging on was fire retardant and I only had smoke damage. But they can be dangerous,good luck.

Glad my nitro heli doesn't decided just to go up in flames. Sorry to hear it happened to you. I don't care what anyone says. Electrics just seem to be a gamble.

(1) He had a charger over charge a pack........
(2) He flew said pack
(3) It failed....as it will almost certainly do every time in an overcharge situation.

You nitro will go up in flames if you spill nitro on the outside of the heli and light it with a match....oh wait you would not do that, just like he should not have flown that pack.
Bad luck on the charger but I would definitley keep an eye on that one.....Ron

Really, How many of us would not have flown that pack. He discharged it then cycled the pack on the charger and all was well. I have seen people fly puffed packs for many flights with no issues.

I'm not trying to say it was right or wrong, just more of us would have flown the pack than not.

Sorry for your loss that sucks.

Thanks for the positive thoughts Rick. I agree with you 100%. I know that a lot of us would've flown it. As I stated above, I cycled it after the overcharge issue and everything seemed fine. The cells balanced pretty close to normal and the puffing wasn't bad to begin with. You could just see a slight curve if you look at the pack from the side. I guess I was in the wrong for not taking it easy to see how it handles. I didn't do a hard flight but still pushed it a bit.

I have learned my lesson that's for sure. I tore the heli apart last night and found that most all of the damage can be fixed by just replacing the frames. They cost about $70 each side. The canopy has no damage at all, the head and tail are both fine too. Luckily all of the electronics survived the flames. No wires got melted, just some smoke damage.

Really tho, I don't "have" to replace the frames. They just look beat up and chared. Everything still works fine. The tray slides in and out ok. I just want it to look pretty again. I guess all said and done, this could've been soooo much worse. I did loose a set of packs and frames but that's all.

I just wanted to share with you my experience to keep everyone on their toes when flying these big electrics. There is a ton of things that could go wrong in this hobby and this is prob in the top 3 of all. If it had happened to you, you'll know how scary of a situation it was. We sat at the feild for prob an hour just trying to wrap out heads around what just happened.

Ok maybe I was a little hard but I personally would have tossed that pack and got the charger replaced. Glad that all was bad was the frames though

No harm done. I understand completely. I, without a doubt was not as causious as i shouldve been with the pack after that happened. I personally like that charger, I know that others don't care for it much tho... It has been great until this incident. I've had it for almost a yr now. I'm going to try to update the firmware and go from there. If that doesn't seem to hold up ill definitely be looking into getting a PL8

Please get a different charger. I had 4 chargers replaced over 2 years with that charger. They are fundamentaly flawed. Every single local pilot except one has abandoned that charger. It over charges, loses calibration you name it. Firmware doest fix it either. TP replaced 4 ones for me and I said enough. I don't bash products. I was hardcore TP charger user. All I would use. That charger is unsafe. Read thread on rcgroups. It's failures are a mile long. I don't know if it is qc or software flaw. That charger is just plain unsafe.

Anything but that will do fine for you.

I have seen a lot of nitros chicken dance themselves to death to total and complete destruction. Seems more likely than a lipo fire. Been Lipo for years and had one fire after a severe crash. The batteries ejected so no fire damage to chopper.
I have never seen a lipo setup chicken dance itself to death.

I think about the hereafter. I go somewhere to get something, then wonder what I'm here after ?

Gentlemen,

Please do not lose perspective of the real issue, which has nothing to do with E vs N bickering.

The problem here is malfunctioning charger, or as Norman described, a possible product line of bad chargers.

If you own or know someone that owns one of these TP chargers, please take note.

Is a misfortune to hear of a fellow modeler experience a fire and loss of components, but to blame all electric systems and batteries for being "potentially" dangerous is ignorant and petty.

Why do we not use the Consumer Product Safety Commission to report such issues?

Yea, how come TP hasn't addressed this issue with further safty precaution. All they said is that we have realesed a new firmware to correct it. What if its too late for that? I smoked a couple $150 packs and the possibilities are endless on how much worse this could've been.

What am I supposed to do with this charger? I won't be able to sell it here. TP won't refund it. Am I just out $250 pluss the cost of a new system?

Send it back to TP and maybe use the credit for new lipos (I think that is the LEAST they could do) ....and then buy an original I-Charger or Voltz Charger (not from HK as those are clones and DO NOT have the same componentry).........Ron
