Leaving Li-ion batteries on the charger overnight is never a good idea.
That being said I always use quality cells such as AW or Redilast.
You have to remember , that not everybody knows about charger that is known to over charge cells, or not to leave batteries in the charger overnight...
There is hundreds of lights and other electronics using 18650 online ( eBay for example ), where sellers offers battery packs and chargers with no name on It and without any manual...
If you think its awious to everybody what to do or not regarding to 18650 , you are just wrong.
And Yes, single battery can also blow...
