I've read that charging lithiums with an ordinary alternator can smoke your alternator. Investigate before doing that.
There are many myths designed to scare you into not improving your life.
Alternators come in two flavors.. both are current limited and the myth is since Iithiums can take a rapid charge they will draw more than the alternator can deliver and burn it out... Nope. alternator knows what it can deliver and won't exceed that amount.
Li's however do take a slightly higher voltage.. Oh that could pop a diode.. Again nope.. it won't.
It might not exceed its max amperage but they can over heat and burn up trying to put out max amperage at idle, unless they have temperature protection. I charge a pair of 280ah LifeP04 batteries and they will take all the amperage I can throw at them until about 95% SOC when they start tapering off the amperage.
