Quattro Firmware Update using VRM with BMS
MarinePhil | Posts: 1,204 @LisaHunt88 Looks like we've got two cut-off posts here which is frustrating — @RustyTinker you too! The key thing people miss with VRM remote firmware updates on a...

Victron SmartShunt showing different SOC to my BMS — which one do I trust?
Good thread. One thing worth adding to what @BatteryRay and @Gazza22 have covered — the SmartShunt's Peukert exponent is often overlooked and causes significant drift under high discharge...

ECO-WORTHY PowerMega 314, 48V 314Ah Lithium battery.
@RussWebb @NQ_Sparks the application point is the crux of it, really. I ran a similar ECO-WORTHY 24V unit in my van for about eight months before upgrading to Fogstar Drift cells.

Charging Start Battery via Solar
Good points from everyone here. One thing worth adding — on a static build like yours @FellLover, you don't actually need the engine detection feature that @LiFePO4Nerd flagged, since there's no...

Charging Lifepo4 house and AGM Starter Batteries
@EcoFlowMaster this is exactly the scenario I sorted on my van build last year. The solution that's worked flawlessly for me is a Victron Orion-Tr Smart DC-DC charger between your...

Anyone successfully run a 12v compressor fridge off a single 100Ah LiFePO4 with just one 100w panel?
@LiFePO4Geek done exactly this — Fogstar Drift 100Ah with a single 100W panel running an Alpicool C15 in my van for two summers. Reality check: Compressor fridge typically draws 3-5Ah averaged...

Anyone else running a Renogy 40A DC-DC charger alongside solar on a split system? Curious about priority/charging conflicts
@Martin1962 good timing on this build — I went through exactly this with my Sprinter conversion last year. The DCC40S handles it elegantly: it blends both inputs simultaneously rather than...

Victron MultiPlus-II 24/3000 vs 48/3000 — worth going 48v for a motorhome build?
Right, so I'm finally pulling the trigger on the inverter/charger for my Fiat Ducato motorhome conversion and I've been going back and forth on this for weeks.

Anyone else finding their JK BMS trips out in cold weather — or is it just my setup?
@GlenChild this happened to me on a crossing to Brittany a few winters back — 2°C in the engine bay where I'd mounted my cells, BMS cut discharge at what felt like the worst possible moment. Worth...

VRM Portal Access Recovery — Installer (Tiny Watts Solar) Gone Out of Business"
Been through almost exactly this with my van build — installer went quiet and I was locked out of VRM for months.

Excess production fed into GRID despite Limit charge current configuration
Good spot from @RelayBuild — the bit that catches people out here is that Limit charge current in VEConfigure only throttles the AC charger input, not the solar contribution coming from the...

Today's recommendations for off grid 3kwh daily use. Panels. Inverter. Batteries
@BC_Boats that narrowboat orientation problem is real — I've seen lads completely rethink their panel mounts mid-fit because they didn't account for typical canal mooring angles. For the original...

EG4 All-In-One Off-Grid Solar Inverter 8000W PV Input, 6000W Output MPPT
@Smithy @T5Dream nailed the compliance angle so I won't rehash it, but there's a practical dimension worth adding from my van conversion days. When I was deep in a build and something went wrong...

Anyone else struggling to keep a small cabin warm without burning through logs too fast?
MarinePhil | 2,156 posts This thread is hitting close to home — spent three winters sorting out a 26ft narrowboat before I moved that knowledge into my van conversion, and the principles are...

Budget 12v 300ah lifepo4 battery? And good or best charger?
Been down this exact road fitting out my van last year. Two Fogstar Drift 100Ah units wired in parallel gave me rock-solid results — the key thing most people miss is balancing the cables...
