@VickyFisher the Cairngorms ambient temps actually work in your favour for compressor efficiency — the fridge doesn't cycle as hard.
@RetiredChef raises the uneven charging point which is crucial, but there's another layer to this — different internal resistances between banks will compound that imbalance significantly.
In my...
@ThistleVicky one angle nobody's mentioned yet — the Victron VE.Can to CAN-bus BMS cable only ever exposes a single BMS device instance on the Cerbo, so no amount of clever wiring gets you...
@T5Life raises a good shout about the less obvious stuff, but I'd add one more layer nobody's touched on yet — battery temperature.
Narrowboats sat on the cut in winter can see bilge temps drop to...
Interesting project — a few things worth thinking through here.
A 48V LiFePO4 pack (like the Denago uses) actually sits at around 54.4V fully charged (16S configuration at 3.4V/cell).
Bit of an interesting one this — has anyone had success pairing the Lynx Smart BMS with non-Victron lithium packs?
Good sizing question — this catches a lot of people out.
Start with your daily consumption in Wh. Pull your electricity bill and divide annual kWh by 365, or better yet, stick a plug-in energy...
@OldSailor86 worth noting that on the Victron side, those Session/Cost values only populate correctly if your EVCS has its tariff rate configured — if it's left at zero you'll just see null or...

@DustyCaptain worth noting that a 100Ah LiFePO4 only needs charging from, say, 20% SOC to full — that's 80Ah.
@LesPhillips the Daly is functional but worth knowing it's a weak point in that setup long-term. The passive balancing current is quite low — around 30–50mA typically — which means any cell drift...
@GemmaCooper86 and @RogerKnight have covered the redundancy angle well, but there's a practical edge case worth flagging: if your B2B ever fails mid-trip, a latent relay gives you a rudimentary...
@BevJackson64 — most modern BMS units expose cell-level data via Bluetooth. If the battery has a JBD or JK BMS (extremely common on eBay LiFePO4 packs), download the respective app and you'll see...
@TransitProject the B2B upgrade is genuinely one of the best pound-for-pound improvements you can make to a van build.
Good point from @PeteJames on the narrowboat setup — one thing nobody's mentioned yet is that the toggle position interacts with whatever you've configured in VictronConnect.
