It's just one big 12v battery in 4 pieces. Of course it's possible, and the smaller the amperage of the charger, the longer it will take.
Yes that is it! 4 easy to carry 67 pound batteries with a total capacity of 440 amp hours!
So if you have a 45 amp converter/charger, it might take 2 hours to get it from 50% full to 70% full and about 6 more hours to get it to 85% full and perhaps as many as 6 more hours to get it from 85% to 96% full.
You are best off just running your generator about 1 hour in the morning and night, and it will charge the battery from 50% full to about 65% full in 1 hour. This is plenty of power to get through most nights, unless you have a CPAP and really use a lot of power nightly!
You do not need to have a 65 or 70 amp charger. 45 amps is plenty. I have a 70 amp charger built into my inverter/charger. I rarely use it, and then normally set it to run only at 50% capacity, that is 35 amps max output. Over 45 amps, and the battery tends to get warm, and the inverter fan comes on. While not nearly as noisy as the generator, I don't like overheating the battery.
Mainly I use my solar system to slowly charge the battery. It takes all day to put back 120 amp hours, but it does, and I like to watch a lot of TV while out dry camping! Basically I hate campgrounds, except the state parks with lots of space between the sites, and no electrical power is typical there. BLM land with more than 300 feet between the next RV is what I look for!
Good luck,
