self discharge rate

[John Frum]

My system has been sitting idle for a couple of weeks.
The weakest cell in the pack dropped ~2mv in the last 24 hours.
Pack is at 24.4 volts and no balancing has occurred.
These are eve cells from Basen.
Anyone seen this or similar?
What is the typical self discharge rate for the eve cells?
I don't think the spec sheet mentions it.
Off to double check.

>=95% after 30 days.

FWIW, my Eve cells are sitting at 3.46V after being fully charged about 4 months ago.
