So I've been scratching my head over this for a few weeks now. I've got a 2019 Transit Custom conversion with a 200Ah lithium leisure battery (Fogstar Drift 200), and I recently fitted a Victron...

Hey @MaxShaw, worth checking your input voltage under load — if the alternator's output is drooping at all when it gets warm, the Orion will back off its output to compensate.

Rodney3 | 847 posts @CliffSpirit good shout on the EU22i — rock solid bit of kit. I'm in similar latitude territory (North Wales) and run an Ecoflow Delta Pro as my main buffer with a Yamaha...

@LazyNomad I've got Fogstar Drift cells in my static and they've been solid, but for a boat I'd actually push you harder toward them than I would for a land setup.

Been running Drift cells myself — though mine are in a 48V bank feeding a Victron Multiplus for whole-house backup out here in Kent.

@MuddyTrekker that 24/3000 is a cracking find at £280 — I picked up a MultiPlus II 48/3000 about two years back and it's been faultless. The thing people don't realise is the PowerControl feature...

So I've been living on a narrowboat for three years, right, which means I've developed a slightly unhealthy relationship with Victron kit and Fogstar cells.

Curious about something similar on my narrowboat — I've got a Renogy DCC40S paired with 300W of panels through a Victron SmartSolar 100/30, and I've been wondering whether the two charge sources...

Picked up a pair of 200Ah LiFePO4 prismatic cells last week from a seller in Birmingham, came with a 24V 100A Daly BMS already wired in.

Aye, looks like the forum ate everyone's replies as well as the OP — quite the mystery thread this one!

ExTrucker63 | 1,204 posts @GlenSimon one thing worth looking at that nobody's touched on yet — have you checked whether your DC-DC charger is drawing any parasitic current when the van's parked...

@MultiPlusFan this is almost certainly a combination of your absorption/float thresholds being set too high for winter conditions and the MPPT's algorithm being overly conservative when array...

Ella1974 | 📍 North Yorkshire | ⚡ 320W / 150Ah LiFePO4 @BPH_Boats One thing I'd add — ask the seller for the serial number before handing over any cash and check it on Victron's website.

MarineSophie | 214 posts @BorderWanderer North-facing roof on my cabin too — honestly the tilt angle saved me more than anything else.

Compo27 | 89 posts Something worth considering that nobody's touched on yet — AGMs have a notoriously narrow voltage window compared to flooded cells, which makes voltage-based SOC estimation even...

Been running a fairly standard 12V setup in my Transit-based van for the past three years — 100Ah AGM, 200W of solar on the roof, and a Victron MPPT 75/15 controller.

@JennyPalmer same boat here literally (narrowboat life 😄) — what I found helped massively was adding a third panel.

@MarshSoul worth checking your actual cold-weather Voc calculation. Panel Voc increases roughly 0.3–0.45% per °C below STC (25°C).

On my boat the panels basically become decorative art in December — lovely to look at, absolutely useless for charging my Fogstar lithiums before teatime.

Got a Pi Zero 2 W running on my cabin backup setup — dead cheap and pulls barely any power which matters when you're watching every watt. One thing nobody's mentioned: I've got mine set up to send...
