Wiring Balancers: "bridging" Inputs from one balancer to another

Hello,

I am building up a system consisting of 4x 170Ah, 12V lead AGM batteries in series. I attached the schematic below. I have the following question:

Would it be okay to "bridge" the input to one balancer to the next one like showed in the schematic?

From electrical point of view the plus-minus pairs of two batteries are nearly same polarity, they are connected with busbars or short cables with a crossection >16mm² (still in planning).

But I am not sure if this wiring will lead to problems that will make the Balancing not work... like voltage drops over the Balancer connection cables leading to higher errors in voltage measurement or maybe something else I am not aware of.

The description in the manual does not make it 100% clear to me if this wiring would be okay or not.

Does someone have experience with that?

Regards
