Thanks for the reply. My wife and I have ebikes with the batteries built into the frame. I love mine but now I'm concerned about charging them. I usually do it overnight in the garage. When I build projects I use NiMh batteries. Almost as good, cheaper and safer.
I'd like to know if those comments are true, about not leaving Lithium ion batteries charging too long. There are four things that will cause a lithium ion battery to go Thermo-nuclear:
Shorting them.
Trying to charge them after the voltage has dropped below a certain level.
Overcharging them.
Exposing them to air (punctures).
Due to this, all lithium ion batteries require a battery management system. Leaving them plugged in should just cause the battery manager to stop charging them until they need charging again.
Comments? I'm guessing some of these fires are caused by poorly implemented BMS systems.
Don't know anything about this from personal experience, but I thought I heard a report a while back about a fairly large number of hikers in the UK injured or killed by cows. So I'm guessing, not as dangerous as crocodiles but still best to be careful.
