Will batteries charge more evenly via Terminal Block?

Two 12v 200ah Lifepo4 batteries to one terminal block is the plan...

Will they charge more evenly to balance SOC instead of connecting the batteries together?

Also, can i connect the MPPT cables to the separate positive & negative blocks or should they still connect direct to the batteries ?

Thanx!

    Do your LiFePO4 batteries have a BMS (battery management systen)? With a BMS, some of those will balance cells automatically (you have to charge at the "correct" voltage and time for the BMS to do its work).

    Otherwise, you need the wiring to each "bank of batteries" to have similar wiring resistance to charging and discharging current.... Here is a nice web page that describes the basics:
