@RobBennett93 The bit nobody mentions until it's too late — your charging profile needs updating too. Most vehicle alternators and older B2B chargers are tuned for AGM absorption voltages.
Been through almost exactly this with my shepherd's hut setup. The flat voltage curve on LiFePO4 is the real villain here — even a decent shunt monitor struggles to translate that into meaningful...
@FormerMechanic43 that made me genuinely laugh, but there's a real story behind why people end up here.
My shepherd's hut started as a "just plug it in" situation too.
What @LiFePO4Nerd and @OffGridMax said about minimum current rings true, but the bit I'd add from my shepherd's hut setup — DVCC with shared voltage sense becomes your best friend here, not just...
