Yes, it will work.

The battery near the charger end will charge faster and discharge slower than the battery at the load end.

If you want to balance them, have the charger feed the top negative and bottom positive, have the load tap the bottom negative and the top positive. Now all batteries will charge and discharge uniformly. It is all about balancing the resistance of the wires to every battery.

So this is what you're saying and should look like to help balance all the batteries correct?

Someone did an in-depth analysis of how to wire your batteries to maintain the best balance. The answer was in the middle I think. Anyone know where that thread is? I can’t find it and don’t remember who posted it.

Summary:

ideal is equal wire length for all batteries. Think tree with branches, no 2 batteries on the same path. Paths can merge at nodes, but no battery serves as a node. All batteries pass through same number of nodes too.
