Hello
I am acquiring learning data for a LiFePO4 battery.
Will the status bit change from 4 to 5 after about 5 hours of relaxation time after discharging?

Is it true that LiFePO4 is not needed for more than 5 hours?

Hello Takayuki,

Please reference the document below for updating a complete learning cycle, but yes 5 hours is a good relax period until the first DOD is taken but you can go longer as well without an negative effects taking place. Another thing to note is that if you are stuck on status bit 4 than please reference the FAQ below.
