guess these guys have never seen a nimh or a car battery explode
What a load of propaganda crap . I have had a boat blow to bits because of vented NIMH and I am not alone.
that was my point,yes lipos can catch fire but nimh explode,i have seen this happen and the damage they cause
years ago i had a car battery (lead acid) blow up in my face,can tell you know i will take lipos any day
Nihm and rc boating are the perfect mix for an explosion. How many other applications seal in the cells as we do?Quote:

just goes to show how well people are misinformed especially with the title "worlds most dangerous batteries"
better not tell them most of there phone and laptop batteries are lithium :zip-up:
Is this caused by to much amp draw on Nimh?Quote:

I am also lead to believe that a NIMH cell will vent when charged @ a high current, again with heat being the main cause.

AMEN to that !! Any one who ran NIMH in a boat has done thatQuote:

If he was running BL then there are few, not none, ignition sources.
Just curious.
My Nimh are now in my big tug and crawler. :smile:
