nice work turbo joe.
Thanks...I'm only speaking from what I've seen/done over the last couple years...LOL...my Platinum packs were dented in pretty good, but there's a board and some air space in there, so the actual cells are just fine.

My friend killed a 6000 Maxamps cell in a few days with the same car I have -- same charger, same routine. It had a big dent right on the end and it smashed in the cells. It lost runtime really fast...my Platinum rocked for another year.

Sounds like a personal problem, I have a E-rustler w/ velineon *use to be 5700 mamba* and even hitting 20' jumps I've never even come close to denting or having an issue w/ my maxamps lipos.. then again I am smart enough to secure them in the tray with a velcro strap that can take a beating LOL I have had a few speed run crashes that just about made me cry and my lipo's always came out fine.. teach him how to secure the batteries better and he can save some money

Don't be a dick...LOL...I'm talking about actual racing-style cars that are made for sidexside packs, not a Rustler.

The squishy cells do fine in a tray, but not all cars have trays. Many just have battery posts and they cut right into soft lipos.

LOL? WTF? ROFLMAO!!!!!!

With results like that, re270 really must be a tech rookie like it says. Should pay better attention to your lipos, no such thing as a no brainer.

It's not that. It's what happened before that matters. Details are important - otherwise what's the point?

Well I charged and balanced the battery before I left the house, my son ran it for about 10 or so laps. He caught a pipe and stripped the servo horn so I disconnected the battery from the speed control and put the truck in the bed of my truck. The battery is about a month old and it was not swelled or damaged after his run. So as you put I am a dumbass, please enlighten me with all your infinite R/C wisdom what I possibly could have done to make this battery catch fire.

Who's lipo was it?
Maybe there's a lesson to be learned.
Any more info on what might have gone wrong?
Would you use the same brand again?

I honestly couldn't tell why this happened. As far as the manufacturer, I'm going to wait until I hear back from them before I say who it is.

Yeah I took that down. We get a lot of pictures of lipo damage 'round here as if the image itself proves something. Thanks for the elaboration and let everyone know more details when you hear back.

I would like to know would make a lipo catch fire at idle. I have heard overcharging will do it but It was not charging at the time. I have also heard that if it swells up that means a cell has gone bad, but when I checked it it looked the same as the day I got it. Could a cell go bad without it swelling up?
