What Current Setting to Use for 680 1S Battery: 6A or 7A?

First time 1S user here as well - I'm using 1A - is this correct? 👀

My LAVA 3s pack says charging with 1C - 2C. So in your case that would be anything between 0.6A and 1.3A I think. Please correct me if I'm wrong.

Assuming you're talking about charging rate, 6A against 680mAh is equivalent to 8.82C - pretty dangerous to charge at that rate and significantly reduces battery lifespan. Going above 2C in most cases is not a great idea.

I think you mean .6A or .7A? 1s chargers dont go that high, the Vifly whoopster maxes out at 1.3A per port 

You shouldnt charge at over 3-4C its just gonna become a paper weight after like 20 cycles (best case scenario)

Umm, that is pretty high for 1s. I charge my 550mah with 0.6/0.8 amps. Or maybe you tried to say 0.7 amps. Also whoopstor has only 1.3 amps max.
