Default Lipo Explosion

Just shows how tough lipos really are, but how violent they can become!

Another video of someone abusing a battery.

Which is why we use Lipo sacks or bunkers when charging!

The old sub-C batteries used to explode when they had a problem sending shrapnel everywhere.

It takes a real genius to spray water from a hose on a battery that is still plugged into a charger. Standing nearly downwind from that smoke is also equally as stupid. You don't want to be anywhere near it. It can kill you. It contains arsenic.

Most lipo battery fires are easily avoidable. Don't charge a puffed lipo. Don't charge too fast. My personal preference is 1/2C but I'll go up to 1C if I'm in a hurry. I'll go no faster, regardless of what the manufacturer or anyone else says is safe. Make sure your charger is set correctly. These simple things would avoid most accidents since they are mostly due to user error. For those few that are freak accidents, and they do sometimes happen, that's why we charge in a fire bag, preferably away from anything combustible such as carpet and in a well ventilated area.

To generate channel views is my guess.

I wish people would quit calling these an explosion, it is a lipo fire.
at no point was there an explosion that shot out shrapnel.

I've done/seen a couple using a screw driver at no time have a seen an explosion.

and to me its one of the best ways to get rid of a bad battery

I bought a new battery last week - it came with *gasp* instructions and get this! I read them.

It unequivocally stated never charging below 1c and "recommended" not exceeding 2c. It's 9200 mha so that means 9.2 amps MINIMUM and 18.4 amps max.

My battery never had a minimum charge recommendation. My main point was we always see people asking how fast they can charge a certain battery. "Can I charge at 5C?" and so forth and so on. Can you? Maybe. Should you? I'd say never, under any circumstances.

I only brought it up because I'd never seen a minimum rate before. Just something to think about.

So its a 3 cell and its at 16 volts...At 4.2 per cell that comes out to 12.6 volts roughly at peak. Is this guy overcharging on purpose just to start a fire. That does nothing but show stupidity. If charged correctly this wouldnt happen.

I guess that's an interesting question. Is charging too slow bad for a battery? If so, then clearly there is a sweet spot.

Just got 2 new Venom LiPo's last week and nowhere is it listed in the instructions or precautions about a minimum charge rate. It specifically states to charge at 1C and not to exceed that rate.
Also, these videos seem a bit redundant these days...everyone knows by now not to charge LiPo's with damaged cells and to always use a fire resistant charging/storage bag/box and location. If not, you obviously have never read anything about LiPo's and shouldn't be messing with them.

thats just wrong,if a battery is 5300mah then you charge at no more than 5.3 amps,your 9200 should be charged at no more than 9.2 amps,that is the max,going more will lead to it going puffy or just like in the vid,i still cant understand why anyone wants to push lipos so much, to charge at more than 1c on a 2s lipo is madness regardless of manufacturers quotes,turnigy say you can charge at 5c,im not in such a hurry that i have to damage my lipos doing so,we all need to be responsible or itll lead to a fatality one day,more from the fumes than shrapnel

yeah, that's how I interpreted it. Showing that the packs are "tough" by the duration in which they can survive an over voltage/charge. 'Twas probably a fun little experiment.
