Lithium Ion batteries combusting?

I have Li-ion batteries in 2 of my bikes, and love the low weight and long life, but after hearing so many reports of Li-ion battery fires I decided to buy an AGM for the GPz750 I just bought.
Now I think I'll take them out my other bikes, and keep them outside and away.
At my age, I've experienced enough weird bad luck.

A guy on KZ Rider burned down his workshop, when a LI-ion power tool battery caught fire. Rob S is our resident expert on such fires in NYC.
 
A bit more info would be good. If there's 2 fires for 2M Li-ion sold, I'd not even think about it, ... If 10K fires from 2M Li-ions sold I'd think about it a whole lot.
 
You are correct, sir. While ten thousand violent, hard to extinguish fires would give me pause, it's still nothing to soil your panties over

Besides, it's going to be a cold winter. :eek:

Well, this article from Motorcycle.com is reassuring:

"Lithium battery myths
We’ve all heard stories about lithium batteries that have caught fire. While we certainly don’t want that to happen to our bikes, the fear is mostly misplaced. The fires we typically read about are with lithium-ion batteries, the types of batteries that power small electronics, like smartphones and laptop computers. In motorcycle applications, the batteries are constructed from a lithium-iron-phosphate blend that gives up a little in its power density for significantly more chemical stability than traditional lithium-ion batteries.
Additionally, in the case of powersports lithium battery failures, most of these occurred in batteries without Battery Management Systems (BMS). The electronics necessary to balance the discharge/recharge loads on a lithium battery have advanced to the level that the BMS shuts the battery down when an overcharge situation that could potentially lead to overheating and/or fire is encountered."

I must admit, I've never heard of a motorcycle (ICE) battery fire. Electric bikes, yes. Good lord, yes!
There are shops with a few dozen older bikes and batteries all on the charger at once, and...:(
 
Li batteries have different charging requirements compared to flooded batteries. If I'm not mistaken, the charge voltage is lower, so you should use a special R/R. Between the cost of the battery and a new R/R, one would have to ask the question, "is it worth it?" My view: buy an AMG battery, and SH775. The weight difference is not enough to notice.

This has very much been my experience .... I keep a tablet on my coffee table and it is always plugged in . On two tablets the screen has had a minor explosion where the screen cracks and bulges out due to rapid expansion of the battery . Scared the crap out of me because it was loud both times but there was no fire ..... My current tablet I spent a little more money on . It has a feature that will charge to 100% but if it senses that it is plugged in allows the battery to fall to 79% and maintains that level ..... The only way you can get back to 100% is to unplug it and allow it to discharge down to below 50% . It will then charge to 100% and the cycle will repeat itself if I leave it plugged in .....
