Default Dangers of Nickel Batteries!

From the IFMAR Worlds with a rash of at least 2 teams blowing up nickel cells!



Wow! It was a miracle no one was hurt!

Maybe IFMAR and ROAR need to take a hard look at Nickel battery safety!!!!

Yeah but we have no idea what amp they were charged at either. If they were abused that could be the issues as well. I personally have not had any issues with the Nimh myself and all the ones I have seen with issues have been user error of some sort.

I have witnessed a similiar situation. The racers charger malfunctioned.
It is not only nickel battery safety but the whole charging process.
Be thankful nobody got hurt.....

More like...with it being the Worlds they were trying to push their equipment to the absolute edge and sometimes beyond in search of 'just a little extra'....

Any cell technology is dangerous if mistreated.

ChrisP is right. It's the Worlds, of course you push equipment to the limit. Sometimes with the above results.

Seems these nickel battery explosions and fires are happening more and more as the mah capacity goes up on them.

At one of the local tracks that has an oval with alot of 4 cell racers and probably over half the racers there in the other classes on the off road and oval tracks use li-po batteries with all the battery fires this year including one racers trailer buring up all his RC equipment were all caused by nickel batteries.

I agree everybody should take alot of care in handling and charging any kind of battery no matter what kind it is!

It's not always overcharging. You can solder them wrong (too much heat and plug the vent) and have them blow while charging OR discharging (racing). I've seen (heard) it several times at local tracks and it's not just the hard-core racers.
