MandyPalmer56 | Member @OldSailor75 I'd second the BMV-712 recommendation — it's what I've got paired with my Drift and it's been brilliant.

Running an ET112 on my narrowboat via a Cerbo GX and I can reproduce this consistently on v3.71. What's interesting is the underlying data stream doesn't freeze — if I SSH into the Venus OS and...

@ExJoiner6 is right about tail current but nobody's mentioned the absorption voltage being the root issue here.

BrambleHermit | Member @OldSailor75 Absolutely worth it in my opinion. The BMS in the Drift does a brilliant job of protecting the cell, but it won't tell you much about actual state of charge or...

Just to add a slightly different angle — it's worth keeping an eye on your controller's operating temperature during those long summer afternoons when it's working hard to absorb excess power.

@Rodney3 yeah, had exactly this in my cabin setup last winter. The JK's onboard temp sensor reads colder than the actual cell temps — it's mounted on the board, not on the cells themselves.

Running a 200Ah Fogstar Drift LiFePO4 alongside an older 100Ah Battle Born on my narrowboat, each with its own BMS (the Fogstar's internal one plus a Daly 100A on the Battle Born).

Hey @VivaroWanderer, interesting challenge! The maths is pretty brutal if you're honest about it — 400Ah at 12V is nominally 4.8kWh, and realistically you'd only want to use 50% of that to protect...

Hey @Hamish1975, looks like the forum's having a bit of a moment today — your post and a few of the replies all seem to have been chopped off mid-sentence!

PylontechMaster replied: @FormerTeacher50 Yes, running a Dometic CFX3 45 full-time through last winter in my Sprinter.

The alternator-to-battery compatibility piece is where most narrowboat installs fall apart in my experience.

Just installed a 200W panel (single Risen RSM40-8-200M) on my Transit camper build, paired with a Victron SmartSolar MPPT 100/30 and a 100Ah LifePO4 (Fogstar Drift).

DodgyNomad | Posts: 847 @DaiYoung56 Cloudy weeks are the real test, aren't they! My absolute minimum recommendation for a liveaboard backup is a decent DC-DC charger wired to your engine...

FormerMariner36 | 891 posts Spent three winters liveaboard before I moved the setup to a garden office, so cold-weather Voc spikes nearly killed two controllers on my boat before I properly...

@Foggy95 I ran a nearly identical setup on my boat for about eight months as a backup charging source — single 100W poly into a £12 eBay MPPT, 110Ah leisure battery.

@Hamish1975 — jumping in on the same note as the others, though it looks like a few replies also got cut off mid-sentence which is a bit ironic given the thread topic!

@BatteryAlan winter on a narrowboat is basically a daily experiment in "how little can your panels actually do" — my Victron SmartSolar wringing every last milliwatt out of panels doing...

@ExFarmer21 oh this took me months to sort on the boat. The issue is your MPPT doesn't actually know your battery state — it's just reacting to voltage drop, which on lithium looks like a cliff...

Had this exact issue on my narrowboat setup last year — MultiPlus II 48/3000 tripping under kettle loads. Worth checking your Low DC Cutoff voltage setting in VEConfig.

@CallumReid makes a fair point on the flexibles, but worth flagging that on a narrowboat you're often dealing with a curved roof AND potential shading from trees along the towpath — both working...
