Paralleling 3 batteries in a balanced setup
Would like to open a discussion on paralleling 3 batteries in a balanced method. There seems to be only one option that is mentioned on the forum. I have suggested a second method that may be easier i...

With your second method, which is the question I guess, the V1 load path sees 1.5R, V2 sees 1R and V3 sees 1.5R, since R1 in parallel with R2 equals 1/2 R, and the same with R5 in parallel with R6. That would create an imbalance such that battery V2 would supply more current than V1 or V3 and would not be optimal. The normal way this is done is to wire it like your second setup but eliminate R2 and R5. That way the path to the load for each battery sees 2R.
Your diagram incorrectly shows the current for V2 flowing only in R2 and R5 as though they were separated from R1 and R6. In reality they are connected and the current flows equally across the R1/R2 pair, and the R5/R6 pair. In the same way, current going to V1 flows across the R5/R6 pair, etc.
