...Sorry for the title, I mean overnight
...
Safe is a Funny Term.
Is it "Safe" to leave a $5.95 Charger on a Pile of Oily Rags charging No-Name Batteries you got off e-Bay Overnight.
Many, if not Most, would say, No.
But here is where it gets Convoluted. What is "Safe".
A High End Charger inside a LiPo Bag sitting inside a Glass Bowl Charging Brand New, Never Stacked, AW IMR's?
I don't leave Batteries Charging when I go to Sleep or Leave the House. Sure, there is only about a 1 in 100,000 chance that things will go Three Mile Island and Burn my House Down.
But if you know me, and the Things that, Against Insurmountable Odds, have happened to me in my Life, you would Understand where I'm coming from.
