Got a right head-scratcher with my setup that I reckon a few of you lot will recognise. Running a Victron MultiPlus-II with an ET112 meter clamped on the output side, and I've got one load that's...
@SuffolkSolar worth noting that 48V LiFePO4 in a metal cabinet creates some interesting busbar routing challenges — particularly keeping positive and negative runs short and symmetrical to avoid...
Good shout from @BrookLover there — BMS disconnects are a sneaky one that catches loads of people out. One thing nobody's mentioned yet: check your actual cable losses between the MPPT and...

@MarinePhil nailed the Fogstar point — those Drift cells have a frustratingly flat voltage curve mid-range, so your Daly is basically just guessing between 20% and 80% SOC like it's on a pub...
Been running a Victron Multiplus-II 24/3000 in my van conversion for about eight months now, and I've had a frustratingly similar experience to what others seem to be reporting after moving up...
@MarineClare had this exact scenario with my garden office setup — Multiplus II and a Fogstar Drift 200Ah.
DriftKing | 634 posts | South West Great thread. One thing nobody's mentioned yet — sync events are your best friend here.

Got a Fogstar Drift 200Ah sitting in my shepherd's hut and I'm trying to work out if it'll keep a small chest freezer ticking over through the night without me waking up to a puddle of sad ice...

Had the exact same drama last spring with my Honda EU22i — pulled the cord about forty times before admitting defeat and actually looking into it properly. Nine times out of ten with a...
Been meaning to post something like this for ages. Running a Pi Zero 2W in the shepherd's hut pulling data via Modbus TCP from the Victron kit — surprisingly capable little thing for the...
Been running this exact combo on my narrowboat for about eighteen months now, so thought I'd chip in. My setup is a 280Ah DIY LFP pack with a JK BMS wired up to a Victron SmartSolar 100/30.
@AZY_Marine right so quick maths from someone who's definitely not an engineer but has killed enough batteries to have opinions — 200Ah at 12V = 2.4kWh, but you're not touching that last 20%...

@WhatsAFuse65 makes a fair point but I'd add — it's not just the bank capacity, it's your BMS continuous discharge rating.
@MarineGeoff useful to know the translation cheers — seen this crop up on French forums when I was researching my shepherd's hut build. Common culprits for voltage drop on a 100/20...
@OldSailor78 yeah the BMS issue is the thing that kills me about budget batteries — not the cells themselves necessarily, just the protection circuitry is garbage under real load. I run Fogstar...

Great thread @VickyFisher! I've been running a similar setup on my off-grid cabin for about eight months now.
@ExChippie October in the Lakes with roof panels is basically decorative at that point — mine were generating less than my kettle uses just thinking about boiling. Ended up running a Victron...
@ForestDaz finish your sentence mate, we're all hanging here like a soggy solar panel in November. But yeah — had this exact faff on my narrowboat when I was tinkering with the Quattro setup.

@SuffolkSolar great project — I went down a similar rabbit hole for my narrowboat build last year. One thing worth thinking about with 48V packs in metal enclosures: busbar routing and inter-cell...

CaddyProject | 312 posts | Array Worth adding the practical workflow I use: BMV-712 = my day-to-day SOC reference (Peukert set correctly, tail current dialled in tight) BMS = my protection layer,...
