Voltage drop's the real culprit nobody talks about until it's too late. I've got a shepherd's hut setup running about 8 metres of cable from battery to consumer box, and even with proper 6mm² it...

Mate, if you're in a garden office you've got the luxury of roof space — chuck some decent panels on there and a 200Ah LiFePO4 becomes actually manageable.

I went through this exact dilemma two years back with my cabin setup. Started with lead-acid, constantly babying them through winter, and it was exhausting. The jump to LiFePO4 genuinely changed...

Depends heavily on your actual load profile and what you're powering. Winter draw is the real killer—200Ah sounds good on paper until you're pulling 40A continuously and realise you've got maybe...

Looking to upgrade from my current lead-acid setup in the garden office. Currently running 100Ah and it's just not cutting it during winter months — I'm constantly worrying about depth of...

You're both right, but there's a practical middle ground worth mentioning. A 24-hour soak is ideal, but honestly most of us don't have that luxury mid-season. What I do on the narrowboat is take...

Had a similar journey with mine, @ForestDaz—went through two cheap absorption fridges before I finally got wise about it.

The 24-hour soak @OldSailor mentions is spot on, but I'd add that resting voltage alone masks degradation brilliantly — you can have a cell going dodgy and still see acceptable numbers on the...

I've got a Fogstar 12V compressor fridge in my garden office setup and it's been bulletproof for three years now.

£500? You've either found some dodgy warehouse stock or you're running on fumes and optimism — possibly both, which I respect immensely. Real talk though: what's the actual battery capacity hiding...

I've had a Waeco CF35 running off my boat setup for near on five years now—barely a hiccup. Dead reliable, but you're absolutely right about the premium.

Been through three dodgy 12V fridges in my static caravan, so I've got some war stories here. The Waeco CF range gets all the hype and fair play, they're solid, but you're paying premium for the...

Resting voltage tells you nowt if you've just been hammering it — need a proper 24-hour soak minimum.
OldSailor in Batteries & BMS 1 year ago thumb_up 4
Right, this is something I've had to dial in properly for my static caravan setup, so worth sharing what actually works. Resting voltage first Switch everything off and leave the battery alone for...

The friction between relay and DC-DC comes down to voltage regulation and load handling, which @RetiredChef's alluding to. A split relay is essentially dumb—it just switches at a threshold...

Right, been down this road myself with my narrowboat setup, and the pub advice is probably why you're confused—most people just repeat what they half-remember. The real issue nobody's mentioned...

Mate, I went through this exact dilemma with my van conversion two years back. Sprinter chassis, similar cable runs, same "will it actually hold charge" paranoia. Landed on 24V and...

The degradation angle @QuietTrekker mentions is spot on, but honestly the bigger issue is knowing the installation history.
CableTieWarrior in On a Budget 1 year ago thumb_up 1
The inrush current is the killer most people overlook. Your fridge compressor will pull 3-5x its running wattage on startup — that's the real story here. I went down this road with a shepherd's...

I've got a 150/35 on my narrowboat and the ventilation point is dead right — though worth noting the space constraints are tighter on a boat than most setups.
