+A = B = C-
The above battery wiring configuration is what we often see for lead acid batteries. It's simple, but not optimal. For a LiFePO4 battery, it's my theory that this is a bad configuration that could lead to undercharging.
If the BMS in battery A detects that the voltage has reached the limit it will disallow charging (High Voltage Disconnect). It can also do this if one of the cells within the battery exceeds the cell voltage limit. Once the BMS in battery A disallows the charge, it more or less gives the (middle) finger to batteries B and C, which may not have reached their full charge yet.
Is this theory correct?
Note: the above configuration is NOT how I have my two LiFePO4 batteries wired. Both my batteries have equal access to the charge source at the common bus bar. I'm asking for a friend that is new to LiFePO4.
