    Just wondering if I am going to run into trouble here:

    Currently have 48 X 200Ah LiFePO4 in 16s3p configuration as solar battery with 2A JK BMS, considering adding an additional 16 X 315Ah, 16s1p LiFePO4 bank with a second 2A JK BMS in parallel. Both will be connected to a bus bar and then onto inverter.

    Anyone have this configuration and will the imbalance of the resistance of both packs cause much of an issue I am wonering?

    Running 16s4p Calbs and 16s1p 315ah prismatic cells on a jk

    No issues at all, the current is split roughly 2/3 calbs 1/3 prismatic. (The calbs are about 700ah in total)

    Connected them at roughly the same voltage and after a cycle or 2 they have matched up

    That current split would suit alright, thanks @graememk
