EA you know we oval racers are nuts!

10 amps is nothing! I charge a pack at 12 amps atleast once a week 1100 secs is a short time to wait for a pack. But what is even better is when you charge a pack at 24 amps(two GFX's cranked to 12 amps each). I figure if they don't want you charging at 12 then they would not make the charger do it.

All I need now is a special GFX that goes to 13 amps, like the joke in Spinal Tap the movie.

Actually even the cheapest Li-Po's would not put themselves through a wall just burn it a little bit. I have often said the new hi-voltage Ni-MH are more dangerous then the worst Li-Po's when mis-handled. Maybe this will shine some light on what I have said in the past and open the eye's to those that think Li-Po are more dangerous.

When it comes to user error what's more dangerous a Grenade or a Torch?

Luckily Kokam Li-Po's are niether.

Makes you wonder?

"Racing is about the journey not the destination if it wasn't it would simply be called Arriving"

"The solution is people need to spend more of their efforts on promoting and finding more people to race with, rather then a personal quest to form a class that they can win at."

last weekend at the Great Lakes Chalenge, (a nitro race) my friend was charging his car off the battery in my rental due to the lack of power at the track, and his battery pack, a 1400ma receiver pack blew all 5 cells, one after another, while in his Kyosho RRR. The force blew the car apart! I had it on video, but somehow managed to erase it when I recorded the mains. It sounded like a shotgun blowing up. One of the cells blew right through a KO servo and the other took out his receiver, and the other destroyed the carbon top deck and battery tray holder. I've never seen anything like it. The rental vehicle sustained minor damage to the engine compartment. From now on, I'm bringing my Honda 700watt generator.
Am I going back racing?...Hmmm.. Not anytime soon... But soon enough.

Why in the world do we program in the mAh values into our chargers when they tend to ignore it? If a charger misses it's delta peak, then it should stop charging at x amount after the mAh are reached. Maybe 10% past or something. For example, if you charge 3000 mAh battery pack, and you program 3000 mAh, it should automatically stop when it reaches 3300 mAh regardless of a delta peak or not.

Many chargers already have this capability. I know on my ICE I can set it to only go a certain percentage over the mAh rating that I enter. Nice safety net.

You know, LiPo's may burn but that could have killed someone...

Imagine someone was sitting where that wall was and that was their head....

Looking at something like this does make me laugh when the guys at my local hobby shop tell people that LiPos are dangerous.

But, pretty much no matter what battery type you use, if you abuse them, they're dangerous.

10amps... Thats just frickin retarded...

I don't know whats scarier, the fact that this one person did it, or the fact that you know other idiots will still do it despite knowing what can happen.

Sign me up for one of those kevlar vest...hell screw that, make full riot gear including a helmet!

One thing a lot of you guys are missing is that IF someone would have been sitting there it would NOT HAVE HAPPENED!! They would have heard the cell Vent or smelled it getting hot and been able to take it OFF THE CHARGER and prevent this!!

This is why all battery chargers, batteries, etc come with a warning... DO NOT LEAVE THIS UNATTENDED WHILE IN USE!!

I am in dis belief of this.

What did the cell push against to get itself into the wall.
For every action there is an equal and opposite reaction.

Also, I charge at 10 amps very frequently, not saying its a good thing to do. I NEVER let the cells peak at that current. Only when I am late for a race and trying to get some Mah in them.

I have heard of cells blowing up though, so I know it can happen, and I understand it is VERY loud!!
