Thanks to @Steve_S for this! Excerpted from another thread.
"I am no expert, just a critical observer.
There is far too much over concern about LFP cells sitting at "FULL" SOC. 3.65V and lower will NOT hurt the cells and over time they will self-discharge albeit quite slowly. The cells never sit there as they will always settle, typically to 3.5** Volts. Where keeping Voltage Hi is a problem, is with people "FLOATING" cells to Hi State. The other problems are also if there is a runner or lazy cell playing games in the battery pack. If FLOAT has to be in the equation due to charger type then it should be set to lower than max charge value, typically around 3.4V per cell equivalent."
I was worried about my cells dropping off 3.65v overnight, but now I know that it is normal.
