Expand Victron Smart 12.8/200Ah LiFeP04 House Bank

Our flooded lead acid house bank is at end-of-life. I would like to start a new 12V bank with 1 or 2 new Victron Smart 12.8/200Ah model BAT512120610, then expand it up to 6 over the course of six months to a year (for a total of 1200Ah) if this is possible.

At the time of capacity expansion, if:
1) all existing batteries are wired in the Posts style (see diagram below); AND
2) the existing bank is fully charged; AND
3) the new battery is also fully charged (via separate IP65); AND
4) voltage is identical on the existing bank and the new battery prior to connection,

is there any reason why this plan would not work?


I understand that the ideal is to have ALL the batteries exactly the same age and SOC from the very beginning, but this isn't always the case.

Perfect moment to switch to a 48V system.
