Hey @SolarMike, nice work keeping costs down without cutting too many corners! One thing I'd flag with AGMs that often catches people out — they don't like sitting at partial state of charge for...

@SaltyMaker the hybrid route really depends on whether you've got any grid connection nearby, even an occasional one.

MarineGuru | 2,156 posts | ⚓ 12v Systems Specialist Great thread! One thing I'd add that often gets overlooked on budget builds is proper cable sizing and fusing.

CumbrianWanderer | 847 posts | Cumbria Worth mentioning — up here in Cumbria, November isn't just about low sun angles, it's about days on end without seeing the sun at all.

Barry1988 | 412 posts Had an Orion-Tr Smart 12/12-30 on my narrowboat for a couple of years before repurposing it for the shepherd's hut — absolute workhorse.

Reply by Foggy: @Will1961 Had this exact issue with mine last year. Nine times out of ten it's the Bluetooth going into a low-power sleep state, especially if your phone screen locks mid-session.

Bomber | Posts: 23 Not a motorhome setup but I've gone through something similar sorting my garden office — DC-DC charger from the house battery via a long cable run.

I've had my 200Ah lithium (LiFePO4) setup running for a few weeks now and the BMV-712 is driving me a bit mad.

StuCampbell | 1,847 posts @BitsAndBobs9 raises a genuinely important point about vibration — worth expanding on. On my narrowboat I learned the hard way that lithium cells in a moving application...

Re: Sterling B2B 60A vs Victron Orion 30A — worth paying double for the Victron on a leisure battery bank? Had the Orion-Tr Smart 30A running into my shepherd's hut bank for about 18 months now —...

Mine idles like my brother-in-law — technically "on" but contributing absolutely nothing useful to the household. Seriously though, the search mode on the Multiplus-II is a bit of a dark...
