Balance configuration for 3 x 12v batteries configured for 36v

Greetings all.

There are configuration diagrams for every configuration imaginable except for a 3 battery, 36v system.

I need a diagram for connecting two battery balancers (or one if that is possible) to three 12v batteries connected in series to create a 36v system.

Please do not just say, “it’s the same as such-and-such” a system. Please give a point to point connection., and knowledgeable and factual explanations are welcome.

I can look at the setup for a 48v system and copy it, dropping the orange wire on the second balancer leaving the black wire as both would be connected to the same point. Would that be correct?

I am sure the solution is simple, and I would like a simple point-to-point answer, but it is nowhere to be found. Getting rid of the 32v system is not the simple answer.

You need 2 balancers, the wiring is the same as for 48V but without the 4th battery and the 3rd balancer.

This setup has been working as expected since you shared it with me in 2020. Thanks Matthias.
