Hey Steve! A 460Ah battery is pretty large so you will want something with a higher output than the 30A # PD49RR you were looking at. A better choice would be the Progressive Dynamics 9300 Series RV Converter Charger - 12V - 60A # PD79RR. This will do a much better job and charge your battery at a faster rate.
If you don't mind spending the extra money you can even move up to the 80A Progressive Dynamics 9300 Series # PD89RR. I looked at the battery specs and assuming it is the 12V-460AH-250A-BT-Black the output would still be under what that battery can handle.
Are you upgrading from a different converter that isn't lithium compatible? What is the amp rating? Depending on what route you go you may have to replace wiring as well so it can handle the output. If you already had a 30A the one above will work with your existing wiring without any concerns, you will just have slower charging.

Hey Steve, how did things go with the Progressive Dynamics converter for your 460Ah lithium battery upgrade? Did the 60A or 80A model end up giving you the charging performance you wanted? Your update could make it easier for others planning a similar swap.
