Even WITH the Sterling B2B, the extra wear on the alternator will make this configuration a very risky proposition.
How do I know? Because I have that exact Sterling and that exact Electrodacus in a T1N, and my Bosch 200 A alternator lasted a total of 16 months of very occasional use before its clutch pulley wore out. My alternator's effective lifespan ended up being measurable in mere HOURS.
What the alternator was DESIGNED to do and what we are ASKING it to do are two different things in this scenario, even if the numbers on paper seem to make sense. Numbers on paper are not equal to conditions of wear in real life.
At this point, I am 100% convinced that the only SAFE non-solar way to charge lithiums in a T1N is by using a second alternator. A second alternator is a very expensive proposition because of the mounting bracket availability issue. For the moment, I will omit those details and that research.
Rather than belabor the alternator failure details in this post, I'd encourage you to read this account of that failure below (non-monetized blog post).
Understand that if your alternator fails the way mine did, it could easily put your rig in danger, and your life in danger, because when its degradation causes the chassis battery voltage to fall too low and the computer to shut down, your T1N is just going to stop dead in the middle of the freeway, wherever you happen to be at that moment (possibly with a 70 mph big rig bearing down on you). That is what will happen if you don't catch that kind of failure in time to save yourself from an uncontrollable shut-down.
