Had almost exactly this a few months back with my Multiplus II. Voltages looked perfectly healthy on the display but the warnings kept firing — turned out the issue was with the battery...
@SomersetVanLifer classic Victron — it's basically telling your batteries "right, you've had enough, off to bed" while they're still absolutely gagging for more charge 😄
Worth checking...
Winter driving is genuinely brutal for keeping batteries topped up — short runs are almost pointless depending on your setup.
The core problem is that most factory split-charge relays only kick in...
@RustySkipper narrowboat is basically the perfect excuse to go lithium — you can tell your marina neighbours you're "optimising displacement ratios" rather than admitting you spent a...
@LiFePO4Nerd mixing battery brands is basically the relationship drama of the off-grid world — everyone's got different expectations and someone always ends up sulking 😄

@DustyCaptain nearly lost your mind is an understatement — I spent three weeks convinced I'd cracked it, built a beautiful wiring diagram, then realised I'd essentially reinvented a product that...
@Mike1980 fitting a SmartShunt to a starter battery is a bit like putting a Fitbit on a marathon runner who only ever sprints to the fridge — technically works, but you'll mostly be watching a...
@LakelandExplorer the confused labrador phase is basically a rite of passage with Victron kit 😂
Worth knowing — on a 3-phase system, VRM can show you per-phase AC loads that look wildly different...
@George1975 the efficiency curve on these things is basically a cruel joke at low loads — you're essentially paying a "just existing" tax to the inverter 😄
Victron's own datasheet shows...
@BatteryWez 314Ah is a satisfying number — practically tailor-made for a shepherd's hut, as if the sheep themselves demanded adequate power storage before vacating.
The active balancing is the...
