Correct, the numbers refer to C-Rate at some combination of Temperature * SOC
That's a little less clear, here is a larger uncropped screenshot:
View attachment 34656
Or view the
full datasheet here
They give seemingly somewhat contradictory guidance.
2.2.6 states 0-60 are the absolute limits
2.2.7 shows very low C-rates under 0
Also bear in mind, while many datasheets have a table similar to this, this one is specific to Ganfeng Lithium 100Ah cell. My purpose of posting was to illustrate the general broad trend and relationship between SOC + Temperature + C-rate, it should not be treated as a reference table for anything beyond that specific cell from that specific manufacturer. From what I've seen there can be meaningful differences between manufacturers
^ This is how I Interpret it too ("when temperature is X and SOC is Y don't exceed a C-rate of Z")
(
@fafrd I responded to your later comments in a PM since its another subject, but short answer, the table above is probably not related to your issue).
