Question:
Is there an upgrade for the Magnetek 7345 45amp unit that will charge lithium batteries and is there any possible issues with trailer wiring problems. If no replacement can I use solar on a lithium battery to get the 14.6 volts for lithium charging while pulling my trailer. Thank you

There is not an upgrade to make the Magnetek 7345 compatible with lithium chemistry battery banks. You will need to completely replace your power center for going to this chemistry battery. I suggest the Progressive Dynamics Mighty Mini AC/DC Panel and Converter/Smart Charger - 45 Amp # PD4045KA. This 2-in-1 AC/DC distribution panel and converter charger keeps your power systems easily accessible inside the RV. It works with lithium and lead acid batteries by using a custom charging profile for lithium and multistage charging for lead acid.
Use of solar panels for charging lithium chemistry battery banks requires a solar controller that is rated for lithium. Such as the Go Power PWM Solar Charge Controller with Bluetooth, # 34276119.
