@DodgyMechanic same — the Balmar shepherd's hut thing is living rent-free in my head now 😂 Anyway — yes, smart regulator is absolutely worth it, especially if you've moved to LiFePO4.

Fair play for shifting them. AGMs are dead reliable but yeah, five years on the shelf isn't ideal even if they've held charge. The real question is — what's the voltage sitting at right now?

Mate, when mine started doing this last year I found it was a dodgy cell connector causing intermittent resistance spikes.
