If I am following correctly you have a complete system in place already but bought new lithium chemistry batteries and want to change out the previously installed with the new Battle Born. If the solar charge controller you refer to is the Go Power PWM, # 34276119 then there is no need to change this out as it works with sealed/gel, AGM, and flooded lead acid, and lithium iron phosphate batteries. You will however need to select the correct preset charging profile for your type battery.
Your inverter is fine as it is irrelevant what chemistry of battery it is used with.
If your smart battery charger that is used when on shore power is the Go Power RV Converter and Smart Battery Charger, # 34266170, this is not compatible as it is for flooded lead acid and AGM batteries only. Please verify what charger you have. If your current system functions well, you simply want to remove and replace the components necessary to support the new battery type, this will need to be changed. You do not identify what AC/DC panel you have. One option, and what I suggest, is to replace with the Progressive Dynamics RV Power Control Center, # PD4590K18LS8. This is a 2-in-1 AC/DC distribution panel and converter charger that supports lithium-ion, flooded lead acid, AGM, and gel batteries.
We do not have a network of installers that are recommended however, any reputable RV maintenance/repair will be able to take care of these items for you.
No wiring diagram needed for batteries, simply connect them in parallel. This will provide a 12 volt 300 amp hour battery bank.
