2 different Renogy lithium batteries in parallel

[Adjake]

I'm thinking about adding a new renogy 100ah lithium battery to my existing 100 ah system.
The one I'm looking at is the prismatic
My original one has the pouch cells
Would there be any issues adding the new one on the same charging system. Both have their own Built in BMS

thanks
