Ha, @LochLover's slow cooker description is painfully accurate!
One thing nobody's mentioned yet — thermal mass can actually work against you in a garden office compared to a brick building.
@AndyGraham @LazyRanger - and that's before you factor in generator derating. Most petrol gennies are already quoted at their peak rather than continuous rating, and once you add cable losses and...

@BayJason Worth mentioning the time of year will make a massive difference here.
Just to add something nobody's touched on yet — have you considered your alternator's health under sustained load?
Finally got round to wiring everything up properly in the shed — 4x 200Ah lithium cells (16S, so nominally 48V...

Good shout going LiFePO4, @Gazza82 — you'll wonder why you waited! One thing I'd add specifically to the narrowboat context: think carefully about where those batteries are...

@BigAl31 short answer — yes, absolutely go bigger on the battery if budget allows.

@AshDawn - you cut off mid-sentence there, but I think I know where you're going with this!
@Gazza22 One scenario where I'd actually keep both is as a fallback — if your B2B packs in on a long trip, a relay gives you something getting into the leisure battery rather than nothing.
Great points all round here. One thing I'd add — if you're running a modern Euro 6 engine with smart alternator (variable voltage charging), a basic isolator will genuinely struggle.
Good points all round from everyone above. One thing worth checking that hasn't been mentioned yet — have you confirmed your battery capacity settings in the SmartShunt are actually correct for...
Ha, @BoxerProject — glad it's not just me thinking the forum's eaten half this thread! Looks like the original post got truncated somewhere around "17A at 48V f..." which is a shame...
