Fogstar Drift vs others — 2025 battery showdown
Been running a Fogstar Drift 5.12 in my van conversion for about 18 months now, and I reckon it's worth the conversation.

How to set up a Cerbo GX monitoring system
Been running mine hardwired for two years across boat and van setups. The Cerbo needs rock-solid comms with your batteries and inverter — WiFi introduces lag that'll mess with your monitoring...

Battery heating solutions for winter vanlife
The lads above are spot on about the BMS protecting itself — that's non-negotiable with LiFePO4. But here's what actually works: Passive heating is your cheapest start.

Why is my MPPT not reaching full power?
The 150/60 is your bottleneck here, mate. That's a 9kW theoretical max from your array, but the controller can only push 60A — so you're capped at whatever voltage your batteries are sitting at.

DC-DC charger getting very hot — normal?
The Orion's thermal design is actually quite clever — it's passively cooled, so there's no fan to fail, which is brilliant for reliability.

Can I charge LiFePO4 below freezing?
The BMS won't let you charge below 0°C—that's a hard stop to prevent lithium plating on the cells, which properly ruins them.

Sailing yacht off-grid — what works at sea?
Salt corrosion is the real killer, not just the spray itself. Victron's definitely robust, but you need proper IP65+ enclosures and regular inspection of connections—even sealed gear can have...

How to check battery health with a multimeter
@MarineGaz and @RelayNomad are spot on. Resting voltage gives your baseline, but internal resistance is the real health indicator — that's where battery degradation shows up.

How to crimp MC4 connectors properly
The fire risk @BlownFuse mentions is dead serious — I learned that the hard way on my van conversion.

Victron Orion-Tr Smart vs Renogy DCC50S
Been through this choice myself when setting up the van. The Victron edges it on integration—if you're running a Multiplus or MPPT alongside it, the networked comms are worth their weight in gold.

Compressor fridge vs absorption — which for a van?
Compressor's the way forward for a van, honestly. Absorption fridges are rubbish when you're mobile — they hate being on uneven ground and take hours to stabilise temperature-wise. I've got a...

Free/cheap sources of 18650 cells for DIY packs
Salvaging from old laptops works, but the real goldmine is power tool batteries — DeWalt, Makita, Bosch packs.

Sterling B2B charger — still the best?
Sterling B2B chargers are solid units, no question. Mine's been running in the van for four years without a hiccup — handles the jump from alternator to leisure battery smoothly even when the...

Pure sine vs modified sine wave — what's the difference?
The stepped waveform of MSW genuinely does stress reactive components — capacitors and transformers especially. That whining @Lefty72 mentions?

Best tilt angle for UK solar panels year-round?
The 20° pitch is actually pretty decent for year-round generation in the UK — you're not far off the often-quoted 35° sweet spot for winter performance.
