If I want to know the health status of my batteries, I want to know 2 facts: the battery capacity and the (un) balance of the individual battery cells.
Both can be determined by the BMS and supplemented with an Victron Shunt.
It’s a different story if you want to know the status of a used unknown battery, such battery could be damaged by very high charge and dis charge current or a short circuit.
Sounds great 
Will continuo with another track in this thread:
For those running Victron systems for several years:
How do you usually interpret battery behaviour over time in VRM?
VRM provides a lot of data (voltage, current, SoC, temperature, etc.), but I’m curious how people determine whether the battery behaviour is still normal.
For example, do you mainly look at:
voltage behaviour under load
cell balance
SoC patterns
charge/discharge behaviour
temperature trends
Or do you rely mostly on BMS information?
Just interested in how people interpret the VRM data in practice.
Only way to tell with my old Lifepo’s is to test them. They are batteries in a sealed case with no way to access any information.
