Best battery charger options
I’m running (2) 6v 215AH gc2’s wired in series for a 12 volt system. I am trying to figure out the best/quickest way to charge them with a generator. We will have limited times where we can use the g...

how fast you can charge is highly dependent on the generator and battery type. Most 2000W generators can run a 60A converter a few a 75A with nothing else on before they overload.
If you have a 3KW generator you could run a 100A converter.
Next check what the battery can take. I have 4 GC-2's and run a PD75A and PF 55 in parallel at times and start an intial charge at 120A or so. Basically the same as 60A on a pair.
Progressive dynamics or Iota are FAR FAR FAR better than a WFCO. The WFCO will likely never give you more than about 15-20 A charging current regarless.
And it won't get you a full charge at home.
And in any case you can get the batteries up to about 80%SOC pretty quick. The last 20% will take hours regarless of converter so when the batteries hit 80% cut the generator. For the last 20% solar is a good choice, or full charge at home.
