I think best upgrade for dry camping would buy the best batteries eg. true deep cycle and a separate charger.
You seem to be really hung up on specific gravity. Specific gravity is the best way to make sure that each cell is healthy and it's true state of charge but I fail to see what your problem is with my decision along with 1000s of other RVrs who have decided to care for their batteries in the best way possible and by battery manufacturer and industry standards by choosing to change to a quality 3 stage charger from a 2 stage charger.
I have made the switch to Trojan T-125 6volt deep cycle batteries over a year ago. I have 260 watts of solar panels on my roof. The charge controller for the solar panels is a true 3 stage providing 14.4 volts when needed to care for my batteries.
So exactly what is the issue with wanting and requiring the same type of charging quality out of my converter/charger? Are you saying that a 2 stage is sufficient over a 3 stage charger? If so why?
The long and short of it is that it is MY money I am spending, not yours. It is MY battery bank and I feel I am making a very good and sound decision in how I am maintaining it. My decision is not based on only "one factor" but research I have done using data gathered from industry leaders like Trojan, Exide, Xantrex, WFCO as well as the testimonials of many other RVrs who have been doing the dry camping thing for much longer than I have and those who have also made the decision to change to 3 stage chargers. Are you saying ALL those people are wrong?
It's obvious from your posts you don't agree with my decision, I get it. However it is my decision, my rig, my $1200 battery bank that I have to pay for if it gets screwed up and for that fact I am going to spend what it takes based on the best information out there how to care for it, not just one factor like specific gravity!
For what it's worth a WFCO or PDI 3 stage converter/charger only runs about $200 give or take, slightly more than I have paid for 1 battery in my 6 battery bank. I think it is a very wise decision to pay the money for a good 3 stage charger and stop killing them with the worthless converter supplied in my rig. And yes I do own a hydrometer and yes I do check SG on a normal basis.
