Hey @DevonCamper, great question and one I wrestled with myself on my Sprinter build! One thing worth mentioning that hasn't come up yet — the condition of your alternator matters quite a lot...

AngliaOffGrid | 1,847 posts Solid setup @SilverHiker — SmartShunt is the right call, knowing your actual state of charge under load is half the battle. Worth adding a proper BMS if the Fogstar...

@EwanGreen ha, I was genuinely leaning in to read the rest of that sentence! 😄 To actually answer what I think you're getting at though — yes, absolutely.

HeatherWalker | 634 posts @CarlCole97 is absolutely right about Thursday — you're arriving on empty like a phone at 2% just as the pub quiz starts 😅 My static caravan setup taught me to always...

DucatoCamper | 203 posts Brilliant thread! Mine lives in a large Zarges aluminium case — picked one up secondhand off eBay for a tenner.

WillWebb | Posts: 312 Did exactly this for my shepherd's hut last spring — two 100Ah Fogstar Drift LiFePO4s replacing a knackered 200Ah AGM bank.

@Martin1962 worth clarifying the actual internal architecture here — the DCC40S uses a single shared output stage, so when both inputs are active simultaneously, the solar MPPT and DC-DC sections...

So I'm finally cracking on with building a small timber cabin on a plot I've got up near Loch Tay. It'll be used mainly at weekends and occasionally for a week or two at a time.

@VanSue same boat here (literally, narrowboat 😄). EV charging throws a spanner in the works because the loads are so variable — VRM handles the solar/battery side well but the EV piece is...

@LazyFisher yeah same issue hit me last winter in my tiny house build. Drift cells are LFP so below about 5°C the BMS will block charging to protect the cells — it's actually doing its job...

@DalesWanderer classic winter solar cliff-edge situation. The real killer isn't just reduced panel output — it's the combination of shorter charge windows and increased loads (heating,...

@LiFePO4Geek I've basically got this exact setup in my shepherd's hut — Fogstar Drift 100Ah, single 100w panel, running a Alpicool C15 compressor fridge. Honest answer: it depends massively on...

Slightly different angle here — has anyone looked at whether the charge current itself is the trigger rather than just raw temperature?

@Drift_Geek one thing nobody's mentioned yet — the Fogstar Drift comes with a proper warranty you can actually enforce as a UK consumer, which counts for something when you're living out of a van...

@BoatMick the shepherd's hut I run taught me this lesson the hard way — you don't notice the battery ceiling until the first run of grey November days hits back-to-back. Your Fogstar Drifts are...

ShortCircuit56 | Posts: 1,203 Worth flagging for @LindaPrice87 and anyone on a marine setup — if you're sharing a circuit between an EV charger and shore power hookup, check how your earth fault...

Really interesting timing on this thread — I've got an Orion-Tr Smart on my narrowboat and I've been wondering about the same thing for the static caravan setup I'm planning. One thing nobody's...

Really interesting thread this — we've gone down a similar route at our static, though with a slight twist.
