EmmaButler | 847 posts @ROW_OffGrid I've been running 14.2V absorption with a fairly short absorption time — around 20 minutes — on a similar Fogstar setup and it's been solid.

Picked up a 200Ah lithium (EVE cells, 4S) build off eBay a couple of months back and fitted a JK BMS — the 200A active balancer version.

@MidlandsNomad one thing worth mentioning that I don't think the others have touched on yet — the Orion-Tr Smart's Bluetooth integration pairs really nicely with the Victron ecosystem if you ever...

DownsOffGrid | 634 posts @JimChapman74 One thing nobody's mentioned yet - how's your panel orientation?

@Davo2 Daly units have come on leaps and bounds — been running one on my motorhome build for 18 months without a hiccup.

@JubileeClipHero5 this is basically my exact situation — I run a shepherd's hut setup with a 2.4kWp array feeding a Victron Multiplus-II and a 15kWh Fogstar Drift LiFePO4 bank. EV charging off it...

@EdKelly Following on from what @QG_Marine was hinting at — thermal mass differences between cells can really exaggerate cold-weather imbalance.

Really common with Daly units in my experience. Worth checking what your actual charge current limit is set to in the BMS software — the default from Daly is often far more conservative than the...

@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?
