Yeah, noticed the same @JimKelly. Part of it's probably the pound taking a hammering against the dollar over the past year or so — these cells are priced in USD at source and the margins get...

The DC-DC is doing a different job entirely — it's charging from the alternator properly rather than just piggybacking off the chassis battery.

SolarJason | 512 posts | 🔋 Battery Obsessive @GarySmith58 The bit nobody mentions — JK's low-temp cutoff defaults are conservative from factory, often set around 5°C charge protection.

Hey @RustyTinker, worth checking what your BMS cut-off voltage is set to as well. LiFePO4 cells don't love being discharged hard in very cold temps — most BMS units will throttle or trip earlier...

QuietSparky | 1,203 posts Worth checking what low-temperature cutoff your BMS is configured for — many ship with charging protection kicking in around 5°C, which is actually correct behaviour...

Great thread @Spud! I've got a Drift 100Ah doing something similar on our boat, though mine's semi-integrated rather than fully isolated — it sits on its own bus bar with a manual isolator switch...

@Nobby30 — saw exactly this on my shepherd's hut setup last winter and it took me an embarrassingly long time to work out what was happening. Short version: cold panels are more efficient, so your...

@CrispyWelder snap — virtually the same stack on my boat. The Cerbo is genuinely transformative once you accept its quirks with non-Victron gear. The trick I found was using a Victron Smart Shunt...

@Moorey40 this is basically the origin story for every single person on this forum, isn't it 😄 My shepherds hut started as "just a couple of panels to run a lamp and charge my phone."...

So I've got a 2006 Westerly Griffon that I live aboard about four months a year, mostly down at Lymington.

Tommo30 | 147 posts @WrongFuse96 nice one, that Fogstar Drift is a cracking bit of kit for the money. Curious what your actual loads are day-to-day?

EdHamilton | 412 posts | Member @Titch is almost certainly right about the MultiPlus — it handles the transfer switching internally, which is the whole point of that unit.

Good shout from @SaltyMaker on the insulation front. One thing nobody's mentioned yet — have you checked your cell-level voltages under load?

Mine did the same in my garden office setup — turned out the absorption time in VictronConnect was set embarrassingly short, basically treating the battery like it had already done its cardio when...
Robbo51 | 1,243 posts @DefenderSolar worth knowing that Fogstar actually recommend doing a proper top-balance before first use regardless of how they arrive — it's in their documentation if you...

Updated the VictronConnect app on my Android yesterday (v6.00 something, can't remember the exact build) and now the battery status screen on my SmartShunt 500A just looks completely different to...

@MartinParker64 Something nobody's mentioned yet — check your battery temperature compensation settings.

HeatherWalker | 312 posts My JK did exactly this in my static caravan last January — turns out the low temp cutoff was set to 5°C which sounds fine until you realise your pack spent the night at...

@HazelPaddy — yes, this is a well-known headache and you've stumbled into one of the genuinely problematic LiFePO4 applications. The core issue: LiFePO4 has a very flat discharge curve, so your...

SunnyTinker | 312 posts @MandyMorris worth checking whether it's actually the BMS cutting out or the inverter/load dropping below the low-voltage threshold.
