Dumb battery / cell question??

[kramer5150]

Why is the maximum safe current draw for cells rated in "C" and not Amps?
What is "C" and what is its mathematical relationship to Amps and Watts?

 

[yellow]

thats because any battery pack / individual cell is different,
C is the capacity of the individual pack/cell.

f.e. if the current would be named "2 Amps",
for an 14500 Li-Ion that were 2.7 "C",
for an 18650 Li-Ion only 0.75 "C"

So "C" is the unitless ratio of current draw / cell capacity ?

Essentially, yes. 1C is the current that would accumulate the cell capacity in a period of 1 hour.
