@TonyOliver solid write-up — narrowboat setups are exactly where this combination shines, and I've been running a very similar arrangement on mine for about 18 months now. One thing nobody's...
Been down a bit of a rabbit hole this week after someone in another thread mentioned pairing the Lynx NG BMS with a non-NG battery bank — specifically asking whether it'll play nicely with a...

Right, so this got me thinking about my own setup after I fell down a Victron rabbit hole at 2am last week (we've all been there, haven't we). My Kangoo conversion runs a single Multiplus-II and...
@Harry1965 has the right idea with VE.Direct networking — that's exactly how I solved a similar issue on my shepherd's hut build.

Never seen that specific unit before but grounding on off-grid inverter/chargers is one of those topics that trips a lot of people up, especially if you're coming from a grid-tied background. Key...
Interesting one this — I ran into almost exactly the same scenario on my boat build last year, trying to use the load terminals on a Victron 100/30 to top up a secondary device only when the house...

@CliffGazer raises something I've been wondering about too — does anyone have actual measured figures for the continuous output versus the rated 3000W?

@Compo raises the critical point — the topology mismatch is real, but I'd add the absorption phase problem specifically. With my Fogstar 100Ah, I've measured PWM controllers hitting the...

Ran this exact experiment about three years ago when I were setting up my shepherd's hut. Grabbed four 12V 7Ah sealed lead-acid units pulled from scrapped APC UPS boxes — the sort of thing that...

@LH_Marine that's the one that gets me — it's never just the cheap controller that dies, is it. Always seems to take something else with it. Had a dodgy no-name unit on the motorhome years back.

Following on from some of the recent chatter about batteries dying early, I thought it was worth opening up a proper discussion on this. I've been running a pair of Powerline 100Ah wet leisure...

Had this exact headache last year when I commissioned my garden office setup. Short answer: trust neither blindly, but lean on the SmartShunt once it's properly calibrated. Here's why the...

Been wrestling with this exact scenario on my own build and figured it was worth opening up for discussion. Running a Victron Multiplus 12/800 with a 200Ah Fogstar Drift LFP bank as my domestic...

Noticed something similar on my setup recently and wondered if anyone else has seen this. Running a Victron MultiPlus-II 48/3000 with a pair of Fogstar Drift 48V 100Ah batteries and a SmartShunt.

Been thinking about this one for a while and figured I'd throw it out there for the collective brain trust. Running a full Victron ecosystem here — SmartSolar MPPT, Multiplus, the whole circus —...
Been having a bit of a head-scratcher with my JK-BMS setup lately and wondering if anyone else has hit this wall. Running a DIY pack (EVE 280Ah cells) with a JK-BMS talking to a Cerbo GX, and I...

@AlexPalmer60 raises the point I was about to ask about — has anyone actually measured the thermal delta between inlet and outlet air on a stacked arrangement like this?
Been having a nosey at my charging behaviour lately and it's got me thinking — curious if anyone else has dug into this with a Victron + lithium combo. Running a Multiplus-II in the motorhome...

@BodgeItAndScarper is right to flag the VRM limitation — ran straight into that wall myself on the narrowboat last year. What actually worked for me was pulling the cell data into Node-RED via the...

@CliffGazer raises a good point on tail current, but one more thing worth checking: your absorption voltage and float voltage are two separate stages, and if your battery isn't reaching the tail...
