New 6 volt batteries, problem?
Hey everyone, Hoping for some input on the new battery situation. We have a 2015 class C, about one year old next month. I’ve replaced the converter in my WFCO 8955 with a Progressive Dynamics 9270...

Unfortunately, I don’t think I have access to a 6v charger, to try and bring up the one batt.
True, I only fired up the engine for a moment (<30 seconds) and looked at the volt meter and afterwards thought it maybe should have been higher. The voltage was checked at the battery. I know it’s got to be near a 20’ run, maybe more, from the alternator to the battery, so I just chalked it up to voltage drop there.
Update after first night, still seeing a more voltage drop than previously experienced on light 5-6 amp loads, dropping to <11.8 now under these loads this morning. Looking forward to replacing them, as I can tell already they will have more capacity than what they replaced. I really wish I had room for 4 batteries, if I get two more, will have to locate the second pair 15’ away in a compartment and deal with venting as well. Still thinking about it, but will probably be happy enough with two for now.
I think we will make it through the weekend fine, and I will likely be exchanging these. The place I got them from received a newer shipment since I purchased these, and will be examining the replacements closely before taking them home. Maybe an upgrade to the 125's would be nice.

I saw 13.2 at the batteries while the engine is running. This is, all, however immediate after being plugged in for 3 days into the PD 9270.

You should have seen the 13.2 w/o the engine running, if you checked it immediately after disconnecting the PD power. And w/ the engine running, you should have seen 14.2.
Your PD seems fine, but your alternator charging has a problem, as does at least one battery
