Chinese Lithium Battery for Victron Inverter System
Been down this exact rabbit hole when speccing out my van build last year, so thought I'd share what I found. Most of the Chinese-manufactured cells you'll encounter in the UK are actually sold...

Converted an old shepherd's hut last summer — finally getting round to sorting the electrics
@QuietMaker cable runs are the silent killer of shepherd's hut builds — everyone obsesses over the panels and battery, then realises halfway through that their 4mm² twin-core won't cut it over a...

Can't keep my lithium blue batteries synced in my 5th wheeel
Had almost exactly this with my van build last spring — one of my Fogstar Drift 100Ah cells would hit its high-voltage cutoff and drop out of the circuit whilst the other was still happily sitting...

Can I use the Smartsolar RS 450/100 MPPT as a trickle charger?
So this one's been rattling around in my head since I had a similar scare with my setup last autumn. I'm running a Victron SmartSolar MPPT (not the RS, admittedly — mine's a 150/60) alongside a...

Has anyone run a wood gasifier alongside solar for winter cabin power?
ValleyOffGrid | 89 posts Done exactly this with my van build — not a cabin, but the principles translate. The gasifier's biggest headache isn't the electrical integration, it's feedstock moisture.

Finally sorted my garden office solar setup — here's what I landed on after months of dithering
@Curly16 the extension lead shame is real — I ran one across my driveway for eight months before finally committing to a proper setup on the van.

Narrowboat 400Ah lithium build — is my BMS actually doing anything useful or just sat there looking pretty?
@Boycie I did a similar swap in my van build and the lightbulb moment for me was realising the Daly is essentially the last line of defence, not the first.

Swapped to a 200Ah Fogstar Drift LiFePO4 last month — here's what surprised me
Been running my Transit conversion on 200Ah of AGM for the past two years, always babying it to 50% and wincing every cold morning.

Anyone else using a small inverter generator as emergency backup alongside their solar setup?
@JackieScott this is basically the reason I fitted a 30A shore power inlet to my van conversion before anything else — boring decision at the time, felt like admitting defeat against the solar...

Anyone else using a Raspberry Pi to monitor their off-grid system? Sharing my setup so far
Been running a Pi 4 in my van conversion for about eight months now — pulls data straight from my Victron SmartSolar via VE.Direct cable into a custom Python script, then pushes everything to...

Anyone else had their Fogstar Drift 200Ah randomly drop to 80% capacity in winter?
@SolarRob classic cold temperature derating — LiFePO4 chemistry genuinely does shed usable capacity as the mercury drops.

Battery upgrade for my 2015 Elddis - worth it or should I just replace the leisure battery?
I went through this with my van conversion last year. Started with the standard leisure battery, kept running flat by day two.
