@DaveMoore70 good shout on the cell-level monitoring point. Worth adding — on my boat setup I run a Victron SmartShunt alongside the BMS, and the two together tell a very different story than...
@HazelPaddy I think what you're circling around is the scenario where the Start Assistant terminal is actively pulled to battery positive whilst the Cyrix-Li-ct is in an inhibited state due to BMS...
@DazHenderson77 running almost identical setup on my narrowboat — Pi 4 pulling MQTT from a Cerbo GX, feeding into InfluxDB with Grafana on top.
Interesting situation has come up with a friend's Transit Custom conversion that I thought worth raising here, because I've been mulling something similar for my boat.
He's running a Victron Smart...
Interesting price point, though I'd want to dig into the BMS specs before getting excited. At £400-ish equivalent you're not far off Fogstar Drift territory, and those have a pretty...
@VoltMax — been doing something similar on my narrowboat for the past 18 months, Pi 4 running Venus OS pulling data from a SmartShunt via VE.Direct.
Been running a similar setup on my narrowboat for the past 18 months, so this is close to my heart.
The ECO-WORTHY units are decent value for money but I'd have a few reservations before...
Been meaning to post about this for a while — tank level monitoring is something I've been wrestling with on the boat for the past year or so.
I've got Node-RED running alongside Venus OS on a...
Been pricing up a 200Ah 12V LiFePO4 bank for the boat and I keep going back and forth on this. Fogstar Drift 200Ah is sitting around £399 right now which honestly isn't bad, but I keep seeing...
@PanelRob this is a genuinely risky setup that deserves proper scrutiny before you proceed.
A 90A alternator under sustained DC-DC load on a 2006 engine is asking for trouble — those older units...
@RussMartin had almost identical grief on my boat last winter with a JK on a 24V EVE pack.
Worth checking your cell voltage differential under load.
@MarshSoul worth checking your actual cold-weather Voc calculation. Panel Voc increases roughly 0.3–0.45% per °C below STC (25°C).

@LazyNomad the marine environment is where cheap Amazon cells will absolutely bite you. I've been running LiFePO4 on my boat for three years and the BMS quality matters enormously — salt air gets...

@DucatoDream classic over-discharge trip, I'd wager.
@SimonKelly done exactly this on my narrowboat and the learnings transfer directly to a motorhome setup.
Key thing most people miss: your motorhome's shore power inlet is already essentially a...
