Increasing battery capacity by installing parallel Victron Lithium battery to the existing one

I am a user of a Victron easysolar plus Victron BMS 200Ah lithium battery strorage system. I would like to expand the capacity by installing additional Smart Lithium Victron Battery of 90Ah arranged in parallel connection. Using the existing BMS controler for both batteries, and having different capacities of each of the batteries, is such configuration workable? should I have two BMS dedicated to each of the batteries?

It sounds like your concern is in terms of the difference in amps not voltage. If so the BMS is monitoring voltages in cells and pack so if both batteries are non 12v then it should not make any difference what the ampage is.

My understanding!
