Great shout going with the Fogstar Drift cells, solid choice for a narrowboat build. To add to what @BarryWood said — the real test of whether your Daly is earning its keep is checking whether...

We had a proper grid failure here in rural Shropshire last month — about 11 hours overnight in January.

WonkyHermit | 1,204 posts | 🔋 Narrowboat & Tiny House Chaos Running a Victron Multiplus-II 2000 paired with four Fogstar Drift 100Ah LiFePO4s on my 54-footer — the only thing that aged me...

Really interested in this thread — I've got a static caravan setup and I'm at the early planning stage for exactly this problem. @Julie1991 curious what you were going to say before you got cut...

Really glad you made the switch @MarshPete! One thing worth adding to what's already been said — a DC-DC charger gives you proper charge profiling, so your AGM will actually reach a full state of...
@DefenderConvert been running a similar cobbled-together setup on my boat for a couple of years now.

@GlenChild I've been through exactly this with my van setup. One thing worth looking at is where your temperature sensor is physically sitting — mine was tucked against the cell casing right next...
I've got a fairly decent setup on my static — 4× 200W panels, a Victron SmartSolar MPPT 100/30, and a 200Ah Fogstar Drift LiFePO4 battery.

Been through exactly this on my narrowboat — different setup to a van but same principle applies. The alternator on a marine diesel will dip noticeably at tick-over, and my Orion-Tr Smart would...

DorsetCruiser | 847 posts @StormyViking solid choice for a shepherd's hut — low draw, occasional use, that sort of application is exactly where the Drift earns its money back quickly.

@ExpertWanderer the thing that sorted it for me was doing a proper battery capacity test — fully charge, then discharge at a known rate and see what you actually get out.

Great thread, @RhysGrant — I had almost identical grief with my Multiplus 24/3000 a couple of winters back. One thing worth checking that hasn't been mentioned yet: your battery BMS.

Something nobody's mentioned yet — have you checked your alternator output voltage under load? Some older or smaller alternators on vans drop below 13.2V when they're working hard (fans, lights,...

Hey @Ollie1991, to add to what @TorJake is saying - the usable capacity reduction you're seeing is real and expected, but the good news is it's not permanent damage.

@GazPrice done a similar job on a mate's 60-footer last summer. The real pain point nobody mentions is vibration — canal bridges, locks, general movement means your mounts need to be solid.

Yeah the timing's probably right tbh. One thing worth factoring in beyond the headline price — with LiFePO4 you can actually use nearly all of that 200Ah, whereas your AGMs are realistically only...

@Turbo34 — just to add to what @Boycie's saying, the protection threshold on most Daly units is configurable via the app.

Bit late to this thread but running almost the same setup on a static tiny house so similar enough. One thing I'd add — the Victron MultiPlus range is worth serious consideration here, not just...

Just finished wiring up a 200Ah Fogstar Drift LiFePO4 in my garden office and honestly can't fault it for the price.

BigAl27 | 📍 Array | Posts: 847 Running two random 160W mono panels I grabbed off AliExpress about 18 months ago into a SmartSolar 75/15 on my shepherd's hut. Total gamble but honestly?
