Lipo Battery Bomb

[kunas]

heres a pic of my gens ace 1300 3s lipo that i was charging yesterday, maybe 12 cycles on it in a lipo battery bag. house is a black nasty mess but it didnt hurt anything other than melting chargers and wiring, im glad it was in a lipo bag, even in a bag if noone was home my house would have went up in smoke flames were shooting out of bag approx. 18 inches

[Docwolf]

this is why i charge out side..........

[RootBreaker]

wow i started charging in the garage on a piece of metal.. but now you got me thinking!!!!!!!!

[Docwolf]

I want to think you for posting this, i am sorry to see if happen, but it is good to have a reminder of how dangerous these packs can be. not saying don;t use them, just use with caution. I know i have gotten lax is how i charge, that will be changing.

I charge mine in a metal ammo box

[Immarcescibile]

After the smoke issue is it safe to re-use the lipo bag if in decent condition?

[Docwolf]

I would say no, lipo bags are cheap, i am betting the protection level is gone, kinda like not using a helmet again after a wreck.

[gottwins?]

Holy crap. No more charging in the house for me.

Do you use balance plug? Here's why, I bought a used charger and lipos off local club guy and when I got home realized it didn't even have a balance plug. Long story short I refuse to use this thing for lipos because of risk of such fires. Am I wrong in thinking this? Two packs came with charger and are swelled, is this a result of no balance plug or something else? One has a melted deans connector on it...

[Docwolf]

sound abused to me, balancing is important one sell may charger fast then another allowing you to over charge it. balancing not only monitors the cell, but it also puts a small load on it as needed to help insure a even charge.

I am curious of your charge amp rate (how many amps?)
Does your speed control have a lipo low voltage cutoff & what is the voltage its set @?
I assume from your count of cycles you bought it new.

I started using a separate LVD on my rig. I am pretty attentive to my cell voltages after a run, and i found that a few times, one cell would dip low. Although the combined cell voltage was as expected, 3.3V x 3, so 10V, one of the cells was down in the 2.95 range. Thats kind of dangerous. My new LVD alarms if ANY cell drops below 3.3v, not if the combined voltage drops.

I charge in the house, but I am always in the room with it. I think I will get a bag now.

The cheap LVD alarm ($4) is money well spent. And the fact i can see it through the windshield and read my remaining charge is nerdgasmic.

here is the favorite of mine

7.4V -22.2V RC Lipo Battery Low Voltage Tester Checker Alarm Indicator 2s-6s New | eBay

since its not an alarm it wont go off in a power drop but can be viewed and left plugged in during driving

i run mostly tekins set at 3s cutoff and a HH brxl i dont know what voltage it is set at
i charge my batteries amp wise like such
1300 mah= 1.3 amps
1800 mah = 1.8 amps

[Tonysmini]

I always balance charge mine at half of their charge current or at 1.5 amps, whichever is less, as I am not in a rush to get them done, and because I have had enough problems with military radio batteries I know to be wary of them all the time.

The minute one puffs or receives a good whack and gets damaged, it's discharged and off to the recycling centre. It's not worth running the risk with them, as you can see, they can turn around and bite you back.

What exactly happened?
