what would cause my battery pack to get really hot?
I had a RC 1600 mAh NiMH powering my Neuros. It was rubber banded to the back of the Neuros and when I went to check it in my bag I smelled smoke, and both the battery and my neuros were 150+ degrees. The Neuros has burn marks on tha back but is still full functional. The battery pack is shot. there were bare wires coming from the battery pack but I didn't think they'd touch. They ended up melted onto some plastic in my bag. I'm assuming this is the cause and I should connect them more safely next time.
thanx

bwhahaha no

lets say hypothetically the battery was plugged into the Neuros and the + and negative touched. What, hypothetically, should happen?

you create a "short" and your battery just drains itself out, creating LOTS of heat due to excessive current flow. then BOOOOOM if you're unlucky. or just melting plastic.

ok, thank you for confirming my thoughts. there was def. some melted plastic and metal

Definatly a short. People have had batteries and rig bags catch fire from shorts. :o

I've heard of popping cells in a nicad, but have never experienced it. Back in 1990 when I was first getting (heavily) into RC Cars I had a charger that wouldn't ever stop charging (wouldn't go into trickle mode) so one day I set a batt on the charger, forget about it 40 minutes later, and the thing is so hot, its litteraly smoking. Melted plastic, etc.. took it out and put it on the work bench in the garage, leaked out its internal juice ALL OVER...
moral of the story: heat in large amounts is BAD! and nicad juice on your gear would certainly f'up something....
becareful on them hot ass days!

I used to work at an electronics company where we used Lithium batteries. Not Lithium Ion, but straight up lithium. And not like camera battery lithiums, either, those are manufactured to be safe. Anyhow, the lithiums we used are NOT consumer batteries, they could blow up if shorted. C and D size 3.6V batteries. We snuck a stash of 'bad' batteries out one day and used them as target practice when shooting. Those things made a nice explosion. Fun stuff.
