I have set up a new solar panel system for my RV, with 4- 200ah lithium iron phosphate batteries. I don't think they are charging properly. When I purchased the batteries, I did the initial full charge on each battery separately with a lithium iron phosphate specific battery charger to 100%. Now that they're connected to my panels and charge controller. I seem to be getting a very uneven use of the batteries all four seem to be sitting at different states of charge. Some of its rather drastic by 15 to 20% or more. The batteries are in parallel connection and I staggered the connections and the charging point from the charge controller to try and equalize the charge between the batteries. I attached a photo of the way I connected the batteries. I guess my long-winded question is, should I have done something different for the initial charge of the batteries before putting them into the system? Or could something else be causing my inconsistent charge rates between batteries?
