General Specifications of Lithium cell
8.1 Abbreviation Definitions
C1 —— the rated capacity (in ampere-hours) of the cell for a one-hour discharge.
I1 —— a current corresponding to the one-hour discharge capacity (in ampere-hours), which is equal to, in numeral, the C1.
In the following specification 1I1 (A) = 280A.
SOC —— the state of charge.
DOD —— the depth of discharge.
