I have to discuss this with our outfitter as it is beyond my capabilities.... I wish they would offer more AMP on lithium battery option. thanks for taking the time to write. This gives me an idea about other solutions....Charging rate depends on how you wire the alternator to the battery system. A Victron Orion will deliver 30 amps. They to go from absolutely empty State of Charge (SOC), which you should not get to but for simple math's sake, will take 200 Ah / 30A = 6 2/3 hours. If you install 2 Orion in parallel you can cut that in half. Lots of schematics on the Victron website to show you how to do this.
You can also use a Cyrix device under the control of a Victron BMS to run the Bulk charging phase then let an Orion do the Absorbtion phase and then you'll be able to slam 100A or so at the Bulk charging. That will ramp the first 80% or so of the charging in 1.5 hours or so, then hand it over to Orion to finish it off at 30A as you can't slam 100A in until full, you need to let the LiFoPO4 batteries have proper charging phases.
The reality is with only 200Ah, you don't have all that much to put back in each day, so 1 or 2 Orion in parallel will likely do you just fine.
