Charging batterys from a 3500w generator

I am new to the liveaboard scene and I have a new 3500 generator I got on the cheap from a pawn shop due to the cord mechanism being damaged.

I have two 6v golf cart batts which I need to charge and I am trying to figure out a way to charge them as quickly as possible off the 110v or 12v feeds available from the generator. Assuming a three-stage charger is needed needed here I am wondering what is a good brand of marine batt charger under say 250 bucks used or 500 bucks new that will plug into the 110 receptacles on my generator and deliver enough charging amps to top off my 2 6v batts in..let's say a 18-hour period... how many amps -size charger would this be roughly and in light of my low budget, charging needs, and power source for the 3-stage charger ( 3000w/3500w peak basic-type worksite/emergency generator and (other source.... 9.9 Merc outboard w/generator feed...thanks for any ideas ...

Iota DLS-55/IQ4 55 amp smart charger. Draws a max of 13 amps @ 108V or about 1400 watts, so will leave you power for other things.

Current price $218.78 including shipping from Northern Arizona Wind and Sun. Just installed one on a client's boat last weekend.

Great charger for the $$$. Your two golf carts won't take much more than 55 amps charging current anyway, and the Iota can serve that up for as long as needed.

I also use an Iota with the IQ option. Mine is a 45 amp and charges my 4d batteries in a few hours.

Unless the op has a 6 volt charger they will have to be in series.
