PD4655 converter question
I am going to replace my main board assembly of my WFCO 8955 converter with a Progressive Dynamics PD4655 assembly. I know that the PD unit will come with a new 12 volt fuse block assembly, but is it...

After some further conversing with Randy at Best Converter, he is a big fan of the Boondocker Powermax units....more so than the PD units. He says that they charge faster than the PD units do. So now I'm back on the fence. I like the idea of a longer warranty and an easier install, plus they are less expensive. Seems like too good to be true, but before I click the "buy now" button, any final thoughts?
The only issue is the charging profile. As soon as the converter hits 14.6 volts (at the converter) the PowerMax moves down to 13.6 volts to complete the charge. This leaves you charged somewhere about 70% to 90% depending on the charge rate and battery size. The smaller the battery and larger the converter puts you at the lower end close to 70%. Four batteries charged with the small PM should get you closer to 90% but will take a few minutes longer.
PD4600, PD9200 will continue to hold 14.4 volts for a full 4 hours and get you to 90% every time.
Is it a huge big difference. Maybe not. Go a little big with the PD and a little smaller with the PM is my only advice.
