Thank you for your info/opinion. I read that PD was a decent charger and one of the better chargers. More BS I suppose if what you say is true. Now the real problem. My batteries are not sitting on a bench inside a very large room within a very large building. RVs are a fine example of 10 pounds of crap in a 5 pound bag. I will need a charger that will replace the unit that is inside WFCO power panel, as did the Progressive Dynamics replace the original lead acid charger/power supply. These are not just chargers. They need to function as DC power supplies for the RV when they are powered up, supplying RV power while charging the battery bank or when the battery is off-line or missing. I'm not sure if there is an actual difference here in overall charger/power supply design. I guess it's back to the drawing board for me, researching converter/charges for lithium batteries... maybe... if what you say is true. I don't see how PD can exist without severely bad reviews or is this going to all come to a head as the data rolls in? Being an early adopter has it's risks.Ah now we're getting somewhere. Your problem is because Progressive Dynamics has NOT A CLUE how to charge LiFePO4 batteries. They simply slapped a "Li" profile (Li batteries are not rechargeable so really should be Li-Ion or LiFePO4 this shows how little they actually know) on a constant voltage power supply.
Your charger NEVER drops to float. It provides 14.6V forever or until you manually turn it off.
Sadly you're not the first person to be mislead by BS marketing by a lead acid charger company who has not a clue what they are doing. We get called to cunult of a few RV instllations and we've seen this same charger ruin more than a handfull of banks and we're not even in the RV industry.
Scrap that boat anchor of a charger and get a real charger, one that is 100% custom programable (Victron IP22 or Skylla IP65) for your next set of Relion batteries.. This is not the fault of Relion it is 150% the fault of Progressive Dynamics.
This industry has become the wild west of BS..... So damn frustrating...
Question: Would I be better off going back to the original, I think settable, lead acid charger from WFCO if I can't get something to fit?
