high everybody,at the end of summer i had a few tech topics about the house battery,I found out that the 2 batteries I had was the problem one was cheap and the other fail the load test so it was bad.I,m getting the rv ready for use and I decided that I am gong to install 6 interstate u2400 battery in the rv because we do alot of dry camp.I was looking at my converter/charger and its a magnetec 950-2-4.It looks like its the original equipment that came with the rv and my question is should I upgrade to a better one.The shop recommends the progressive dynamic model pd9260 with built in charge wizard. Would this be I good upgrade or is it a waste of money since the magnetec works.I,m worried about damaging the new batteries.Its going to cost me 145.00 per battery here in BC.and the new converter/charger is 290.00.
