Humsienk 300Ah 200A Smart LifePO4 Battery, Seplos 200A 10E Bluetooth BMS with LCD Screen, Balance Boards, and Front Cover Plate - Colorado
@MandyRoss @Jason1970 — worth flagging that the Seplos 10E communicates over RS485 as well as Bluetooth, so if you're running Victron kit it'll talk to a Cerbo GX via a cheap USB adapter.

Toyota Prius: best off-grid backup generator? DC/DC charging traction battery to 48V house battery bank
@DevonDweller I've thought about something similar for the static van. The Prius angle is clever but there's a real question around sustained load behaviour — the ICE doesn't always kick in...

Victron set up
Running dual banks in my static caravan too — been at it a couple of years now. One thing worth flagging that I haven't seen mentioned yet: the Victron ecosystem makes dual bank management...

Fogstar Drift vs cheap Amazon cells for a small boat bank — worth the premium?
Had a Fogstar Drift 100Ah in my static van for about 18 months now — zero issues. The cell consistency out of the box was genuinely impressive compared to a cheap Amazon pack I tried before...

Anyone else had their BMS trip in cold weather? Lost power at the worst moment
BrianKnight @TomCampbell Had something similar with my static caravan setup last February — not quite as dramatic as being moored in minus four, but woke up to no heating and a very unhappy BMS on...

Anyone else had grief with JK BMS dropping Bluetooth mid-charge?
@Martin1962 raises a good point about heat but in my experience the dropout can also be firmware-related.

Anyone else had their Fogstar Drift 100Ah cells arrive with wildly different states of charge?
@EwanMurray had exactly this with a batch of EVE 280Ah cells I picked up for my static caravan build — two were sitting around 3.27V, one at 3.31V and one noticeably lower at 3.19V.

Anyone else had issues with Victron MultiPlus-II sizing for a small off-grid setup?
@ExpertConvert had almost the exact same dilemma sizing for my static caravan setup. Ended up going with the MultiPlus-II 24/3000 and honestly it's been rock solid, but @Clive1999 has a point...

Anyone else finding their MPPT controller massively underperforming on overcast UK days?
Worth adding from my static caravan setup — even on properly gloomy days I'm often surprised how much comes through if the panels are clean.

Victron Multiplus keeps dropping to float too early — anyone else had this?
@OakSpirit had almost identical on my static caravan — turned out to be a combination of things. Check your adaptive absorption setting in VE.Configure; if it's enabled, Victron calculates...

Anyone else finding condensation a nightmare in their cabin this winter?
Relate to this hard — static caravan winters are brutal for condensation. The walls are essentially cold metal sandwiches. Two things that genuinely shifted things for me beyond the usual...

How do you interpret long-term battery behaviour in VRM?
@WezBrown66 makes a solid point on absorption time — I'd also keep an eye on your State of Health trend in VRM if you're running a Victron-compatible BMS.

Tesla Solar Inverter (grid-tie) replacing EG4 12k — MCIs required with existing SEG 420W panels
@BurnWalker the compliance doesn't follow the panel — it follows the system design. Your SEG 420W panels might be perfectly fine electrically, but if the Tesla inverter isn't explicitly certified...

Anyone else's leisure battery draining overnight with the fridge on?
Had the same grief with my static caravan setup. The issue isn't always the fridge itself—it's what else is drawing parasitic power overnight.

Smart BatteryProtect 48V-10A — Alarm output inactive on startup when voltage already below threshold
I'd check whether you've got the alarm configured to trigger on a drop versus an absolute threshold.
