Yes, Samsung, LG, Sony if you can get them. I'm very "anal" about 18650/21700 battery safety. I have seen perfectly brand new cheap ones just vent for no good reason and it aint pretty.
Really? It never happened to me even after shorting one once.. There are some super cheap ones at the local Chinese store I was thinking of trying out, the brand ones are pretty reasonable already though, so that's what I use. Maybe will give the cheapies a miss at least for indoor projects
