Max Charging Current of typical GC2 battery

Now,

Try parallel 2-banks 4 batteries with a typical onboard converter.

Start engine. Waste time.

An RV converter stops charging at about 90% state of charge. Keep it in mind.

Using a 1,500 lb oxen (your generator) to power a Little Red Wagon, toy converter. Waste of a good generator and noise pollution.

Say the GC2 battery bank has been drawn down to 25-50%, what will be the max current they will initially accept?

For sure it's greater than the ~24A max my solar charger has reported as that was limited by the solar panel outputs.

that also depends on the battery bank. Is this a pair of GC2's, or 4?

Thanks, that's a lot of amps!

If ya extrapolate both sides of BFL's ugly graph, I suggest 90-100A would get the battery to 14.4v in short order and then taper from there. His graph is based on starting @ 50% with a charger that would max @ 14.4v, @70A, his 2GC held 70A for 30 minutes before hitting the charger set pt and tapering.
