The fasttech samsung 18650s, the protection won’t be that reliable but as long as you will always without fail use a good charger then they should be safe enough. The reports I’ve read of protection failing has always been cheap protection. They all seem to use the same chip, DW01 fortune semiconductor. In fact just today there was a post on protection that malfunctioned. link That why I always point people toward seiko protected Evva or Keeppower.
For high amp use that is the one place where you often can’t use protected batteries. The overcurrent protection is normally not set high enough and it trips on you. Those samsung 25R are among the best choice for high amps. Its what I would go for. And that seller saftymind is trustworthy. http://www.ebay.com/itm/291309619722
If you must charge overnight get a metal box to charge in. Ammo box or cash box. If the batteries “vent with flame” it will contain the flames & you can just worry about getting away from the cloud of gas. I was just talking about how nasty the vented gas and chemicals are in this thread today. They do make lipo guard fire resistant bags but the cheap ones on ebay will burn through.
