That's correct Maurice. Everything with your Progressive Dynamics 4000 Series RV Converter w/ Charge Wizard and AC/DC Distribution Panel item # PD4060K is functioning correctly. The converter output with no load is 13.6 VDC and on full load it'll be less than 12.6 VDC.

You would need to use the Progressive Dynamics 9300 Series RV Converter Charger item # PD79RR to charge up to 14.6 V.

If you have any additional questions go ahead and throw them into the comment box below and I'll be happy to help you.

Hi Gerry. Thank you very much for your answer. So I gest I will have to buy something more that already have to be able to charge my battery to full capacity. I will surely consider buying from you if I decide to. Thanks again. Maurice

@ToG You're welcome! Sadly that is correct and I do recommend purchasing the Progressive Dynamics 9300 Series RV Converter Charger item # PD79RR when you're ready to upgrade. Lithium batteries don't have memory issues like you see in other batteries so you've got some time. What kind of RV or trailer do you have?

@Maurice That's a nice setup! I've seen a few of those at tailgates and never turn down a chance to poke my head in. Got any fun trips planned this year?
