Hi,
Try comparing in watts. 6 x 225 = 1350 watt-hours. 6 x 370 = 2220 watt-hours. In each case 50% is useable. Of course to get to 48 volts you need 8 of each. Few rv's have the space for 8, and few have that much storage capacity.
2220 x 8 = 17760 watt hours, getting you near the range of storage for an electric car.
If you really intend to run a 4400 watt inverter "flat out" you may be better off with 12 volt jars, or if you have the bucks six large 2 volt cells.
The other issue is how to recharge a large bank.

one is 225 amp hrs other is 370 amp hrs.
well it looks like i can only pull(t105) 10 amps per hour and(l16) 18 amps a hr for 20 hrs
its sound like it wouldn't last long powering a camping ? but i feel like this is way more then enough batteries with a 4400watt 48volt magnum inverter
