LiFeO4 batteries can accept charge at very high rates that can overload an alternator if the charge rate is not regulated.
I am looking at using a DC-DC charger to charge batteries from the engine alternator. Watch the input requirements of these vs your alternator capacity. Ray on the "Love Your RV" u tube channel installed one and shows how they work. Their RAM truck has a high amperage connection terminal under the hood.
A rule of thumb we used in heavy trucks was to not exceed 50% of alternator capacity when adding stuff like inverters and fridges etc The alternator does not put out full capacity at low rpm / idle.
I have found solar to be pretty much useless in western Canada in winter.
Because of their fast recharge capability lithiums are particularly suited to "mechanical" charging I'm thinking.
Thanks. I'll look him up and try to find the vid's. It certainly seems like having something like the DC2DC is needed for the "new" type batt's.
And yes to the solar problem on this coast. It has to be accounted for that many reports on solar charging are from more Southern regions, where the sun is high, the skies are clear and there's nary a tree for miles. Bringing a gen. is a must if not driving much. And the ability to charge higher/faster would be best, as well as not doing damage if you don't charge to 100%.
