Not quite so. The voltage depends on the charging current. If a battery has an equilibrium voltage (at I = 0) 12 V and internal resistance 20 mOhms, for I = 50 A the charging voltage needs to be 13 V, and for 100 A respectively 14 V.
I have two 12V AGM batteries connected to the panels via MMPT charge controller 150/85. The battery is for example at 95% charge. The charge controller is saying that it has 15 amps of current to send to the battery, but when I view my battery monitor, it is showing that only 8 amps of charge. Is this due to the state of the solar controller?
There are many types of BMS (and many definitions of "normal"), but generally, in case of too high a charging current, a BMS will not limit the current to an acceptable level but simply stop the charging, and yes, this does protect the battery, but there will be no charging.
The Battery State of Charge (SoC) is the ratio of the current charge in the battery to its maximum possible charge. It is like a fuel gauge for batteries. For example, if a 1000mAh battery only gives 800mAh, it has 80% of its original capacity. 2. Internal Resistance Measurement. How Internal Resistance Reflects the Health of the Battery:
