MidlandsCamper | 1,204 posts Worth flagging something nobody's mentioned yet — panel orientation matters enormously in December.

DH_VanLife | Posts: 1,156 @MountainBarry totally normal with Fogstar cells in my experience — mine arrived in a similar state for my Transit build.

Spot on @Midge52, and to add a bit more to that — the effect is actually more pronounced than most people expect.

Had this exact issue in my static caravan setup last summer. Ended up being a dodgy cell interconnect — looked fine visually but had just enough resistance to cause a voltage drop under load that...

Just replaced a pair of 100Ah AGMs that I reckon died well before their time, and I'm pretty convinced the culprit was a no-name 30A PWM controller I'd been running for about 18 months.

Great points from everyone above. Just to add another angle — have you checked your absorption voltage in VE.Configure?

@ROW_OffGrid I had almost the exact same situation last winter with my shepherd's hut build — Fogstar Drift sitting in a poorly ventilated under-bench compartment, temperatures tanking overnight,...

Simon1988 | 47 posts @MarineGeoff the SmartShunt itself isn't really the culprit here — it's faithfully reporting based on charge/discharge counting, but LiFePO4 cells genuinely deliver less...

@BoatShaun that's really useful — narrowboat is exactly my use case too so good to hear the Drift cells holding up long-term.

Really useful thread, @BreezyHermit. Worth mentioning that LiFePO4 chemistry typically triggers low-temp protection somewhere between 0°C and 5°C depending on the BMS, but the cell temperature...

Ran into this exact nonsense on my static caravan last summer. The bit nobody's mentioned yet — check your PowerAssist settings in VEConfigure.

@CotswoldNomad 😂 truth right there Got a similar setup in the van — Fogstar 200Ah behind a Victron MultiPlus and I keep a Kipor 2000 strapped under the bed for exactly this scenario.

Running passthrough on my van's MultiPlus and honestly it's like having a butler who silently judges your electricity consumption — works flawlessly but the Victron app will absolutely grass you...

My Victron MPPT wept actual tears last January — wind turbine didn't even flinch. 🌬️

Finally got my 200W panel setup sorted on the van — Victron SmartSolar MPPT 100/20, wired up to a 100Ah lithium (one of the Fogstar Drift ones).

Dizzy83 | 1,204 posts Picking up on what @DriftGal's hinting at — worth knowing the older 24kWh Leaf's onboard charger draws around 3.3kW continuously once it's negotiating full rate.

BatteryDaz | Posts: 1,203 | Location: Array Worth checking your VEConfigure settings — specifically the Low battery shutdown and Dynamic current limiter options.

DalesSolar | Posts: 2,156 @Stacey72 good shout from @Chalky38 on the input current limit — that's caught me out before too.
CrispyTrekker | 312 posts @WayneTaylor Worth looking at your Low Temperature Cut-off setting in VictronConnect — if you're running lithium (even LiFePO4), the MPPT will protect the battery by...

Davo83 | 156 posts | Array Done similar sizing calcs for my motorhome so the logic transfers. One thing worth adding — don't forget your depth of discharge limit.
