“ You definitely need a DC-DC charger for charging from your alternator.”
Not necessarily...With 440w of solar and a single 200a/h LFP, I neutered the 7pin plug charging wire as being unnecessary - Harvest swiftly handles everything...And even with the alternator, so long as the amps are kept at a reasonable level for continuous charging (depending on battery C rate and alternator output), of say 25-30% you should not have an issue...
BTW, Victron smart shunts may be a bit pricier (than the China stuff), but so then is your LFP Battery investment, right??
