Hillhater said:Sure,.....but again you are avoiding the point...that there is no totally safe, non flamable , 18650 lithium pack .flippy said:.......and howmany cars that run on liquid dino juice burn down every day for no reason? .....
Remember your statement earlier....
flippy said:18650 is the only way.
a single 18650 hold roughly 10~12Wh, cannot puff up and at worst so some venting at the top. oh, and you need a hammer and chisel to pierce the sides.
so if a 18650 goes thermal you have only a small fraction of your pack going. usually you can acutally still use it.....

i dont see a claim of perfection in there. that is what you make of it.
let me rephrase:
of all the options out there the 18650 form factor is the most safe/least dangerous you can use.
better now?
