charging battery from generator

Need to know the limit of the battery plug connection on Generator. 2 amp, 5 amp, 10 Amp?
Need to know battery charger specifications

Very likely the generator powering your on-board converter or charger. But you can tell us what converter you have and whether it is a "smart" one.

If you have a decent converter, the answer may very well be generator to shore power cord/converter to battery.

The 7 way plug battery connection is just a (comparatively thin) wire that goes to the battery. Better to skip it for use with a generator and connect whatever directly to the battery with appropriately large wires.

Typically the battery connection on a generator is rather low current, intended mainly to recharge a starting battery dedicated to the generator.

Unless you have advanced, intelligent converter already installed, adding one will be the best way.
My camper factory converter will go to overheat when I start charging deeply discharged batteries.
2 hr of generator run charge very little becouse converter was mostly off, cooling down.

The fastest is not always the best way. I would plug the 50/30 amp power cord into the generator and let the convertor charge the batteries.

Generator to battery is what 7 amps? Very slow.
Battery charger? What size? 5 amps is slow 60 amps would be fast.
7 pin connector very slow.

For best results you need 60+ amps and 14.4+ volts right on the battery.

Even better might be solar....

Inexpensive and effective way is to upgrade the converter and be sure there is not too much voltage drop going from converter to battery. Progressive Dynamics converter is $125.00 A real battery charger is about $400

x2 on solar but more money

choice to

Charger, NOT converer

Camper is a new 2016 Grand design Reflection
I am unsure of the convertor in it. The camper is stored
out of town and if I cannot get to it with in a week
battery gets real low. I forget about generator to shore power as another option. Thank you all for suggestions
