Has anyone done any dc to dc charging for lithium batteries. How does it work with the DD alternator?

Basically, in layman's terms they are step-up pulse charger to increase the voltage needed for Lithium batteries in stages to protect the alternator, I installed a Renogy on my daughters RV after replacing the alternator twice,if you have solar hers takes the solar out of the loop to keep from over charging while driving
