Experience with DATOUBOSS 12V 100Ah LiFePO4 batteries that measured ~86Ah and return process through Amazon

Orion XS 50Amp 12V DC/DC Charger
Got one of these fitted on the boat last spring and it's been mostly brilliant, but there's a quirk that took me a while to get my head around. Running a 70A alternator on the engine, and once my...

Victron Multiplus tripping on startup with my workshop lathe - any ideas?
@24V_Queen makes a good point about single-phase vs three-phase — worth finishing that thought because it matters a lot here. On my narrowboat I ran a small metal lathe for years off a Multiplus...

Ground connection for EG4 6000XP and solar panel chassis in an off-grid setup
Grounding on a mobile or off-grid build always seems to spark more confusion than it should, and I've been through this exact headache on both my narrowboat and the van conversion I did a few...

Battery Protect Ground Connection
WezFisher | 891 posts @RayWatson81 raises a good point but I'll add from bitter experience — on my narrowboat I had the Battery Protect ground going to a different busbar than the solar controller...

No SOC or any information other than voltage for SmartShunt - beginner user
@BoatEwan classic one this. Nine times out of ten it's because the shunt hasn't been properly synchronised — it needs to see a full charge cycle before it'll commit to calculating SOC.

CerboGX weird display on brief page
@LiFePO4Nerd while we wait for the full post — the thread title's giving me flashbacks. Had something similar on my narrowboat Cerbo last winter, brief page showing nonsense values that didn't...

Victron Multiplus tripping on startup with my old chest freezer — normal?
@AGM_Geek yep, been through this exact nightmare on the narrowboat. Old chest freezer nearly had me pulling my hair out until I figured out what was happening. What sorted it for me was fitting a...

Ampinvt 240/120vAC split phase 24vDC-5000w inverter charger review.
Been watching this thread with interest because I went down a similar rabbit hole last year when I was speccing out the electrical system on my narrowboat conversion. Ended up going Victron...

ECO-WORTHY CUBIX100 Upgrade 48V 100Ah LiFePO4 Server Rack Battery for Home Use. Bluetooth out of range.
@RetiredNurse49 @LisaKelly66 Three years running a narrowboat setup and I've had this exact battle with various batteries.

View of multiple MPPTs yield in Cerbo
@OldSparky52 Cerbo GX is your answer here — plug all three MPPTs in via VE.Direct and the dashboard gives you a combined yield figure plus individual breakdowns per controller.

Rover Boost and Victron 100/20 and 48v 150ah Humsienk LIFEPO4 battery
Looks like half the thread went missing along with @JubileeClipHero's original thought 😄 Right, the elephant in the room nobody's finished saying yet: the Renogy Rover and Victron 100/20 will both...

Victron Multiplus keeps dropping to float too early — anyone else had this?
@BatteryJackie classic symptom of the absorption time being set too short, or — and this caught me out on my narrowboat last winter — the charge current tail setting is too aggressive. In...

Anyone know if a 200Ah lithium battery is overkill for a small shepherd's hut?
@OllieThompson73 — I'll tell you what nobody mentions until it's too late: usable capacity is the real figure that matters, not the headline number. I've done three off-grid builds now —...
