Great thread. One thing worth flagging that nobody's touched on yet — the Orion-Tr Smart has proper LiFePO4 charge profiles built in, which matters more than people realise with a Fogstar Drift.
@VickyFisher one thing I'd add that nobody's mentioned yet — have you checked your battery monitor or multimeter calibration?

@GlenSimon Worth checking whether your SmartShunt's charge efficiency factor is set correctly — LiFePO4 should be around 99%, but it sometimes defaults to 95% which can...
Running a Victron SmartSolar 100/30 with a 200Ah lithium (a Fogstar Drift 12V) in my van, and over the last few weeks as temperatures have dropped I've noticed the SOC reading on the...

@Lefty28 and @GeoffHenderson80 — the capacity test is a solid starting point, but worth adding that temperature matters a lot when you run it.

Mid-trip season is actually ideal timing if you ask me — you'll feel the benefit immediately rather than waiting until autumn.
Been scratching my head over this one while planning the electrics for my Transit-based build. I've got a Renogy 40A DC-DC charger on order for the leisure battery (a 200Ah LiFePO4), which I know...
Picked up a no-name 100Ah LiFePO4 from a seller on eBay about eight months ago — paid £89 delivered, which felt almost too good to be true.
Been scratching my head with this for a couple of weeks now. I've got a MultiPlus 12/3000/120 paired with a 200Ah lithium (a Fogstar Drift if it matters) and a 40A Victron SmartSolar MPPT.
Finally took the plunge and built a small 12V leisure battery bank for my Transit camper. Went with two 50Ah LiFePO4 cells from a Chinese supplier on AliExpress — came to about £65 all in...
Just to add a practical note to what @WheresMeWires67 and @SilverHiker have already touched on — the key thing to configure properly is your charge voltage setpoints.

Good shout from @WattLiz there — if pinning the GUI resolves it, that does point toward a rendering/display-layer issue rather than anything deeper in the Venus OS data stack itself.
