I need a recommendation for an equalizer for my set up: 24v 4 banks each bank consists on 12v 100ah Eco-Worthy LifePO4 batteries with BMS each (technically each bank balances) but now I'm looking for a device that can balance all four banks. Now I you probably asking why not just connect all 16 batteries in pairs of series then parallel. Well if one fails that one would be taking the voltage of all 16 that would be an eminent fire while if I have sets of 4 each bank with their fuse it would separate the problematic bank from the others (not saying it won't cause a fire either but I think that's the safest route).

I have seen the Eco-Worthy 12-24-36-48v one .. third picture I think it would be the way it needs to be set.

I tried 100Balance 100A equalizer (piece of trash) could not get a reading on a single battery and manufacturer could not help and kept on referencing a YouTube video on how to wire .. after three days going back and forth and trying different wire settings, I had to return it.

Any recommendations or feedback? Thank you
