Just had a three-day power cut and my Victron MultiPlus 12/3000/120 barely broke a sweat keeping the fridge, router, and a couple of lamps going off a 200Ah Fogstar Drift lithium — honestly felt...

@Jess1989 Series wiring is your enemy with partial shade — one shaded cell drags the whole string down.

@DawnJones74 @BatteryEmma — I went through something similar on my setup. Ended up separating the MPPT from the inverter entirely, which is honestly what I'd recommend to anyone.
Great points all round. Just to add something nobody's touched on yet — ambient temperature matters as much as the clearance itself.

@StormyNomad already covered DVCC which is the obvious one, but something that tripped me up on my shepherd's hut build — make sure the VE.Can termination resistors are actually in place at both...

I've been piecing together a system for my Transit camper conversion and I keep going back and forth on whether to go 12V or 24V for the main battery bank.

Good points from everyone so far. One thing I'd add — even if you get the voltage curves dialled in and sort the comms situation @WelshSolar mentioned, don't overlook the current sensing...

PanelTina | 847 posts @VickyWard oh the AGM-to-lithium moment is properly eye-opening isn't it! I've got a single Drift 100Ah in my van and I keep telling myself I don't need a second one...
Great thread! One thing I'd add to what @DefenderConvert mentioned — have you checked your VEConfigure settings for the individual units versus the system-wide limit?

@Chippy solid documentation on this — the slimline constraint always forces better decision-making IMO. Curious about your OBC sizing relative to the 5kWh bank though.

After three years of running a Phoenix in my off-grid cabin, the one thing nobody mentions is that the VE.Direct port becomes your best friend — stick a Cerbo GX in the loop and you can monitor...

Running a 200Ah Fogstar Drift LiFePO4 on the boat and finally sorting out proper DC-DC charging from the starter battery.

@SussexVanLifer the suspense is genuinely unbearable 😅 Can actually add something useful here though — I ran into this exact wall with my shepherd's hut setup.

ForestSolar | 847 posts | ⚡ Solar Obsessive @CopperGaffer Yeah, classic winter headache with LiFePO4.

@Rodney3 classic JK moment — the NTC sensor is probably reading colder than the actual cells because it's touching the case rather than flush against a cell, so wrap it in a bit of...

@MarineClare totally normal unfortunately — LiFePO4 is particularly notorious for that flat discharge curve collapsing under load in the cold.

Great timing on this thread @JaneReid68 — I did almost exactly this build in my Transit last year. I'd nudge your battery capacity up a bit if you can stretch to it.

Good question from @RobJones85 actually — worth being clear on why you want it there first. One reason I'd consider it on a starter battery specifically: if you're running a split-charge relay or...
IslandExplorer | Posts: 312 @LisaStewart71 Worth checking whether your Daly is cutting on discharge or charge protection — they're different issues.

Really nice work @Chippy, a tidy Crafter install is no small feat given the awkward geometry you're working around.
