Question:
I currently have the PD9270 converter. Looking to upgrade to Lithium batteries.....two 12v 165Ah batteries in parallel. Should I go with the PD9360 or PD9360 converter? Current converter is 70A with 6 gauge wire.

Hey Phil, thanks for the information. To replace and upgrade your Progressive Dynamics PD9270 converter, I recommend the Progressive Dynamics 9300 Series RV Converter Charger -item # PD79RR. If you move up to the 80A item # PD89RR you'll have to replace your 6 gauge wiring with 4 gauge wire. It will charge a little bit slower is the only issue.
You listed the same part numbers so I am not sure what the 2nd converter you were looking at was. We do not have a 70 amp one that is compatible with lithium batteries like item # GP99QR.
If you have any additional questions feel free to throw them in the comment box below.
