Your existing converter is only going to put out the same amps as it was before. If you are not adding additional loads and just wanting to increase your run time you will be fine as is.
If you want to upgrade your converter and increase your charging efficiency then a converter that goes to more than 13.6 volts and heavier wire will be needed.
Edit. The switch that I link to up above will also let you run your batteries in two Banks.
The current charger/converter I have is a Progressive Dynamics 4560 rated at 60 amps. It also shows to be a 4 stage charger with a boost mode that puts out 14.4 volts. So I am guessing I should be fine with that. Correct?
