I need some help

I have 4 Lifepo4 24v batteries with built in BMS for each. I have them hooked up in series-parall for 48vdc. I am drawing on all 4 with a 48v motor and a 48v-12v converter. Each battery has its own battery charger and a seperate Solar MPPT charge controler.

Batteries 1 of the first series and Battery 4 of the second series discharge at a different rate and will totaly dicharge if I do not keep them charged.When I charg them they all charge ok but discharge way differetly.
Bat 2&3 are fine. Any ideas how this could happen?
