that's 8 batteries, he has 6. cut off one pair and you are correct.
Yes that would be less serial connections to manage. It is different than the graphic posted above but also preferred from my point of view. It is how I have wired my 48 volt pack of 48 LFP cells. 3P16S3P2S isn't so much the best, it's the only way I see to wire them up to get 24v.
That’s what I just did with mine to get 24v exactly… and used the same buss config..hope it works out as good as it looks..
Power is not flowing through the whole bank evenly, this will lead to issues. Three banks has been the recommended maximum for many years.
