Dragged a 200Ah Fogstar Drift LiFePO4 off the narrowboat and bunged it in the shed — runs the laptop, monitor, a small fan heater on low, and the LED strips no bother.

@WattAndrea — been down exactly that road with my static caravan setup. The Cerbo handles mixed chemistries technically, but you'll want to be careful with your charge profile.

So I've been running a Alpicool CF35 in my Transit conversion for about three months now and I'm constantly waking up to low battery warnings.

@Scouse when your "200Ah" Amazon cells arrive at 140Ah actual capacity, that £80 saving evaporates faster than canal water in July 🚤

Good shout from @Megan1960 on the tail current — that one catches so many people out. Something else worth checking @DaleLover: have you verified your battery capacity setting in the BMV-712...
@Curly raises the sneaky one — also worth checking if that Daly is actually cutting off when it should, because mine looked fine in the app right up until it silently let a cell hit 2.8V and I had...

BrambleHermit replied: @Lisa1978 Something worth considering that hasn't been mentioned — what's your battery temperature like?

@NorfolkBoater — seeing exactly this on my motorhome setup at the moment. Worth checking whether your Voc is exceeding the 100V input limit when temps drop.

Neil1978 | 47 posts @CamperBaz Nice setup — Scottish Borders will definitely test your system come January!

ColJames74 | Posts: 847 @BordersSolar nice upgrade! One thing worth knowing with the Daly specifically — the low temp cutoff kicks in around 0°C and will simply disconnect charging, which can...

Had this in my shepherd's hut last February — brutal wake-up call. Ended up wrapping the battery box with some cheap closed-cell foam insulation and it made a surprising difference.

@OffGridFreak running EV charging from a 1.2kW array is basically asking your solar to sprint a marathon — my boat setup taught me that lesson the expensive way before I started treating the...

@Wardy26 one thing nobody's mentioned yet — the JK BMS has separate low temperature cutoff thresholds for charge and discharge, and they're both enabled by default at relatively conservative...

@WattAndrea running something similar on my boat — Cerbo GX with a mix of LiFePO4 and an older AGM bank. Main thing to watch is the charge profile.

ShaunWebb | 156 posts | ⚡ DIY Enthusiast Great thread! Mine came in at £294 for a modest but solid setup — 200W panel from a Facebook Marketplace find (£45!), a Victron 75/15 MPPT which I reckon...

@KenCrane funny you should mention the EPever — I ran one of those Tracer units in my shepherd's hut build for nearly a season before upgrading.

Running almost the same setup in my Sussex-based Defender conversion, except I went full Fogstar Drift 100Ah and paired a Renogy 40A DC-DC with a Victron SmartSolar 100/20. The thing that caught...

Taffy55 | 📍 Mid Wales | ⚡ Victron/BYD setup @OldSailor78 snap - that exact scenario is what pushed me into sorting proper home backup too.

@Tel1997 had almost exactly this with my shepherd's hut setup last July — scorching week, south-facing roof, and my JK kept cutting out around 2pm each day like clockwork. Turned out the BMS...

Ran mismatched panels on my narrowboat for a couple of years — 2x 100W Renogy plus a random 60W panel I found secondhand.
