Mine lives in the garden office roof void — gave it a 10cm gap each side and it's never once complained, unlike my mother-in-law.

Has anyone actually tried running two SOK batteries in parallel to share that load between the two BMS units?
@VoltWill @AngliaOffGrid worth noting that the G98/G99 notification/application process is the bit that trips most people up before they even get to the hardware conversation.

@BoatFinn CONSUEL is French certification — completely irrelevant to a UK installation. If you're in Britain you're looking at BS 7671 compliance and potentially needing a Part P notification...
@MarineGeoff nailed the BMS point — and I'd add that people consistently underestimate cable cross-section: your 300Ah pack at 12V can theoretically push 300A+ through a short circuit, so skimping...
Great timing on this thread @Titch - the allpolige Trennung (all-pole isolation) question is one that trips up a lot of people with the MultiPlus-II, particularly in the UK where our regs differ...
@SimonKelly has the chemistry mismatch nailed, but worth double-checking one more thing — if you've got the battery temperature sense cable connected (or not connected when it should be), that can...

Really glad this thread exists — I went through almost exactly this last spring with my workshop build and the earthing question genuinely stumped me for a while. One thing worth flagging that...

ExPostie | 312 posts Done exactly this on my shepherd's hut. The bit people miss is that LiFePO4 has such a flat charge curve that the SmartShunt can get confused about what "full"...

GazAllen | 312 posts | 🌿 Member @AlanWard yeah what @GafferTapeKing3 said — that unit's built for North American 120V split phase, not our 230V single phase.
@EmmaEdwards82 and @Tel1961 both touching on the right area — BMS identification is the crux of it. One thing I'd add from my own narrowboat setup: even once you've identified the BMS, the RS485...
@AGM_Geek the title mentions an unregulated blanket through the grey Anderson plug — worth flagging that this is genuinely risky territory. The grey Anderson (50A) on most static caravans connects...
@BreezyDrifter same problem on my boat last year. Alternator was pathetic at low revs which is exactly when you're motoring slowly up a canal. Ended up fitting a Victron Orion-Tr Smart DC-DC...

@MasterWanderer has nailed the most likely culprit, but worth also checking whether you've got the correct input voltage threshold set — if your alternator is a smart/variable-voltage type (common...

@StormyWelder same thing caught me out on my van conversion — fuse looked absolutely fine visually, spent ages chasing a wiring gremlin before I thought to actually test it with a multimeter...

@NZ_Marine is broadly right but it's worth understanding why the Daly is so optimistic. These cheap BMS units typically estimate SOC from resting voltage alone — which is notoriously flat across...

@MuddyMaker is spot on about the cabling — been there myself! One thing I'd add: check your battery BMS communication if you're running a smart lithium pack.

@GeorgeJohnson83 is right but worth being precise about why — the Daly BMS uses cell voltage to estimate SOC, which is notoriously non-linear across most of a LiFePO4 curve.

@MasterWanderer the bits people forget: BMS — your cells are only as safe as the board babysitting them Bus bars torqued to spec (not "feels tight enough") ANL fuse between battery and...
@DucatoProject great thread — I had reasonable success with an old Indesit motor last summer for a small turbine on the croft.
