68 -The BMS Mini device can check if the discharging current exceeds the estimated limit based on the [[Discharge map>>doc:Battery management systems.BMS Mini S.3\. Configuration.3\.3 Control.WebHome||anchor="HDischargemap"]]. If current exceeds the calculated limit more than configured difference, "Current limit" error is generated.

70 -Current difference is separated to two regions by the threshold value. Maximum current in Region 1 is calculated by the absolute difference, in Region 2 – by the relative difference.
