BatteryJason | Posts: 1,203 @DerekDixon AGM is just paying twice — ask me how I know 🔋😭 Went Fogstar Drift 200Ah in the shepherds hut and haven't looked back; pairs beautifully with a Victron...

Love this idea @Spud — I've been thinking about doing exactly this on our 60-footer. One thing worth considering with the Drift as a pure standby unit is keeping it on a trickle maintenance...

I picked up a 24kWh Nissan Leaf gen 1 battery pack off eBay about four months ago for £380. The cells tested at roughly 18kWh usable after degradation, which I'm genuinely happy with for the...

@GoldenMaker interesting experiment. The Multiplus-II 3kVA will technically push enough watts to feed a 7.4kW EVSE but you're going to hit a wall pretty fast — 400Ah LiFePO4 at 24V is only ~9.6kWh...

Running both simultaneously is actually counterproductive in most cases. The split-charge relay was designed for lead-acid chemistry — it'll dump alternator voltage directly at whatever your...

@Mark1978 — 2-3mV after top balance is practically perfect, your cells haven't "drifted badly," they've just remembered they're new and need about 20-30 proper cycles before they settle...

Solid setup @SolarMike! The Victron 75/15 is a great shout even on a tight budget — that bit of kit will outlast everything else in your system tbh. One thing nobody's flagged yet: watch your load...

After the two outages we had in Norfolk last winter (longest was about 6 hours), I've been thinking seriously about a dedicated backup system for my garden office rather than relying on extension...
Been running almost the exact same setup but with a Renogy 40A DC-DC into a 200Ah Fogstar Drift 12V — genuinely curious whether you're seeing any conflict between the two charge sources fighting...

Did this same swap on my boat about 18 months ago — honestly the weight difference alone was worth it.

Had exactly this on my boat last season. Check your battery capacity setting in VEConfigure — if it's set too low, the Multiplus calculates absorption time from that figure and cuts out way before...

Got one of these in my garden office build last year — still going strong. One thing I'd flag that nobody's mentioned yet: keep an eye on the low-temp cutoff.

Really feel for you @Fiona1974 — three days of solid overcast in a shepherd's hut sounds grim. I've been running a 100Ah AGM as a dedicated emergency buffer alongside my main lithium bank for...

Great thread this, been running something similar on my static caravan setup for about 18 months now. One thing nobody's mentioned yet — watch your absorption voltage settings carefully.

Woke up on Saturday morning to find my whole system dead — no loads, inverter offline, the lot. Temperatures had dropped to about -4°C overnight here in the Lakes and my JK BMS (the 200A 8S model...

Great thread — I had something very similar on my 100/20 last spring and it drove me absolutely mad.

MoorClive | 634 posts Good thread, @TinaHenderson. One thing worth adding that nobody's mentioned yet — insulation around the battery itself makes a surprising difference.
