Been running a near-identical setup in my garden office for about 8 months now — 16x Fogstar Drift 280Ah cells, though I went with a Daly Smart BMS rather than the JK.

Squib79 | 578 posts One thing nobody's mentioned yet — double-check your battery sense wiring if you've got it connected.

@AshSeeker this is basically what I do in reverse — I've got a shepherd's hut and a narrowboat, and I've cross-fed between them during emergencies more than once. The main thing to sort is your...

Finally got my off-grid cabin setup stable enough to feel confident posting about it. Running a 400W Renogy panel array feeding into a Victron SmartSolar MPPT 100/30, with a 200Ah Fogstar Drift...

Really useful thread this. One thing I'd add that hasn't been mentioned yet — have you checked what your JK's low temp cutoff is actually set to?

Really interesting thread. I've been wondering about this for my garden office setup — currently running a Victron MultiPlus with a 5.1kWh Fogstar battery, mostly just powering tools and lighting.

RobButler | 📍 Derbyshire Peak District | Posts: 2,156 Good thread this. I'd back up what @Lefty92 is finding — the JBD and JK units especially have come on leaps and bounds.

SolarMike | Senior Member @KenCross great setup! The honest answer is: yes, but with caveats. Your 4kWp will rarely hit peak output here in the UK, so realistically you're looking at seasonal...

Great thread @CumbrianExplorer — cold weather definitely throws the SmartSolar's readings off sometimes. Worth checking your battery temperature compensation settings in the VictronConnect app.

Good timing on this thread — I went through exactly this decision last spring for the cabin setup and ended up going Fogstar Drift after a lot of hand-wringing. The thing that tipped it for me...

Mine idles at about 19W too — turns out the MultiPlus is basically a small electric heater that occasionally charges batteries as a side project.
Really important one that often gets overlooked at the planning stage: winter derating. Your panels will produce a fraction of their rated output on a grey January day in the UK — think 10-15% of...

@StormyViking what threshold are you using for the delta before it triggers an alert? I'm running something similar on the narrowboat — Cerbo GX pulling JK BMS data via MQTT, feeding into...

@VoltAlison meanwhile my Renogy setup in the shepherd's hut has been quietly judging every lead-acid battery owner for two years — welcome to the cult.

So I've ended up in a bit of a situation with my system. Started with two 100Ah AGM batteries I salvaged a couple of years back, then added a pair of Fogstar Drift 100Ah LiFePO4s last spring when...

@OllieThompson73 worth knowing that even with the built-in BMS on each Drift, when you parallel two of them you can get imbalances between the packs over time — each BMS is only managing its own...

ExpertWanderer | 312 posts | Transit owner @VoltAlison great choice! One thing nobody's mentioned yet — keep an eye on your charging sources.

@KeithClark71 had the exact same dropout issue with my 100/20 last summer. Turned out my phone's Bluetooth was the culprit — Android has this aggressive battery optimisation that kills background...
