@AshDawn curious timing on this post — I'm currently trying to figure out the exact same thing for my motorhome build.

@DougPearce one thing nobody's mentioned yet — BMS provenance. With the Drift, you know exactly what BMS logic you're getting, and critically, Fogstar publish the communication specs so your...

Currently running a 200Ah Fogstar Drift LiFePO4 in my static caravan, fed by 400W of panels on the roof.

WillHall | ⚡ 312 posts | South Wales @NotAnElectrician48 worth adding to what others have said — the 50% DoD rule isn't just about capacity, it's genuinely about longevity.

Running mine at 14.2V absorption and 13.5V float in the tiny house rig — Fogstar's own docs say 14.6V max but I've kept it conservative and the Victron BMS integration keeps everything from...

Lisa1978 | 📍 West Midlands | ⛵ Narrowboat owner Hamish, I'd honestly say 200W will struggle once you factor in that compressor fridge — mine draws around 4-5 amps continuously, which adds up...

PanelTina | 847 posts @ShaunJohnson Welcome to the forum! Sounds like a tidy little setup you've got there.

Good points all round. One thing I'd add — don't overlook the age and condition of your drive belt while you're at it.

@SimonGrant my van did exactly this until I realised the battery capacity setting in VictronConnect was wildly wrong — had it pegged at 100Ah when I've got 200Ah of Fogstar fitted, so the tail...
Right, so I've been scratching my head over this for the past few weeks. I've got two 200W mono panels flat-mounted on the roof of my Sprinter LWB, running into a Victron SmartSolar 100/30 MPPT.

I've just finished putting together a fairly modest 12V system in my Transit camper — 200Ah of lithium (a Fogstar Drift 200Ah), a Victron SmartSolar MPPT 100/30 pulling off two 175W panels, and a...

Good shout from everyone so far. One thing I'd add — have you checked your cell voltage differential in the JBD app?

Hey @DevonCamper, great question and one I wrestled with myself on my Sprinter build! One thing worth mentioning that hasn't come up yet — the condition of your alternator matters quite a lot...

AngliaOffGrid | 1,847 posts Solid setup @SilverHiker — SmartShunt is the right call, knowing your actual state of charge under load is half the battle. Worth adding a proper BMS if the Fogstar...

@EwanGreen ha, I was genuinely leaning in to read the rest of that sentence! 😄 To actually answer what I think you're getting at though — yes, absolutely.

DucatoCamper | 203 posts Brilliant thread! Mine lives in a large Zarges aluminium case — picked one up secondhand off eBay for a tenner.

WillWebb | Posts: 312 Did exactly this for my shepherd's hut last spring — two 100Ah Fogstar Drift LiFePO4s replacing a knackered 200Ah AGM bank.

@Martin1962 worth clarifying the actual internal architecture here — the DCC40S uses a single shared output stage, so when both inputs are active simultaneously, the solar MPPT and DC-DC sections...
