Converter kaput need to buy better one.
I'm fairly sure my converter is kaput. It will not charge my 6VX2 Batteries and I want to go to two banks of 6V batteries. I did work for our summer 7 week trip. So how do you size a new converter....

The RV's 30a has nothing to do with the converter size.
The converter size in amps is related to the power output of your generator, measured in VA. A typical converter has 0.7 power factor.
If your generator can run 1600w (VA) as its rating, then your input to the converter can be 1120 watts. Typical converter efficiency is 85% so output would be 952 watts. Output is in DC and you want 14.8v for those 6s, so 952/14.8= 64.3 amps. So you can have a 60 amp converter, but not a 75 amper unless you have more of a generator.
I like the adjustable voltage you get with the PowerMax LK models so you can also crank it to 16.2v for equalizing the 6s every so often as , eg Trojan recommends. Nobody else makes a converter like that, and check out the price!

You can do all four 6s at once with a 100 amp LK, but you need more like a "3000w" generator to run it. Maybe a 2500.
