That's why you ALWAYS use protected cells, if you overdrain them the protection goes pop before anything else does, have you seen what a lithium cell does when damaged, it isn't pretty which is why your choice of charger is also important, perfectly safe when done right of course.
If anyone needs advice just fire away, i've written quite a large light guide on bike radar so can help with choices.
Led tech has come a long way in the past few years, it has overtaken hid and in the end will replace incandescent and fluorescent lights once the lumens per emitter gets high enough, for now they require too much cooling and don't output enough light to fill a room, amazing once you chain a few of them together so that's more than likely what will happen.
Plus you get to pick pretty much what colour you desire, granted these will be the less efficient models but they'll get there.
