Parallax Power Supply 7345
Hi folks I have a 2006 Jayco Eagle and the original IOTA power supply has given up the ghost. I'm looking at replacing it this weekend with a Parallax 7345 that I'm ordering from Amazon.com. I ...

Yes the Paramode Vabs was 14.2 which is lower than ideal for many RV type batteries, especially 6s which really like 14.8 or so.
I did break into the Paramode and use its internal adjustable pot to jack up the Vabs and it worked great after that. Except now the Float voltage was too high. (I didn't do float with it anyway.)
Also mine only lasted a year and then it ate itself for unknown reasons, and Mena's did something similar. An easy fix for a tech apparently, but the warranty procedure looks like a hassle, with you sending it in paying the shipping and then if it is agreed it comes under warranty it gets sorted out. So if shipping is $50, might as well blow that on a new $150 unit and not bother in case they refuse warranty. That's what I did, only I got a PowerMax as a replacement eventually, since I wanted to try one of those.
Temp comp may not matter for charging unless you are in extreme temps or have really fussy batteries. It does matter for the best Float voltage though. 13.2 is for 80F and 13.9 is for 50F so if you have that PD for your winter Float at 49N, doing 13.2, you will still need to do something extra. I don't know if the periodic shot of 14.4 would do much good there. 6s need a periodic run of 15.5 to keep them happy.
On the location of the temp probe, the Paramode had a ring terminal with the temp sensor next to that. So it went on the post. But what happens if your connection with other wires on that post is not perfect? It will heat up! :) So much for accurate temp comp.
PowerMax has a decent line of converters too, I really like mine.
