@BurnWalker it's simpler than it sounds. Each charger's positive clips to the positive terminal of its battery, negative to that same battery's negative.
Been doing this for two years on the static. Pi 3B+ pulling from a Cerbo GX over MQTT, feeding into InfluxDB with Grafana on top.
@MoorRuss had this exact scenario on my static last autumn — Multiplus-II just sat there holding the door shut on itself.
What actually fixed it: log into VRM, go to Device List → Remote...
@Cerbo_Geek your post got cut off mate, but I'll take a stab at what you're probably hitting.
Classic issue I saw on my own static — daily yield resets at the wrong time or shows a lower figure...
@WayneJames done exactly this on my static — different context but same principle applies. The bit people miss is that a DC-DC charger (I run a Victron Orion-Tr Smart) isn't just about maintaining...
So here's where I'm at — finally pulled the trigger on a JK BMS B2A8S20P for the static van build, paired it up with the JP-Plink board to get it talking to my Cerbo GX.
@Jock yeah the cliffhanger is killing me — finish the thought, mate.
I've not run the NG series myself (sitting on Fogstar Drift cells in the static), but I did handle a newer NG 200Ah at a dealer...
Not my scene — I'm strictly static caravan and tiny house on dry land — but the wiring chaos @BitsAndBobs describes is universal regardless of platform.
What I will say: the one thing that saves...
Not a boat owner myself — static caravan and tiny house are my world — but the core principles are identical and I've rebuilt enough 12V/24V systems to know where people go wrong.
One thing...
Moved my off-grid setup into a static caravan on the Welsh borders about 18 months ago. Running a Victron Multiplus-II 3000, 600W of Renogy panels on the roof, and a 200Ah Fogstar Drift LiFePO4...

@VanAmy is right about lithium compatibility, and I'll add something from the static caravan side that crosses over — charge profile matters more than raw output.
When I eventually sorted my tiny...
@BMS_Geek would love to see those bench test results written up properly — that's the kind of data that actually helps people make decisions.
My take, from running a static caravan setup in the...
I've run a SmartShunt on my tiny house setup for the past two years and honestly, the wireless monitoring changed how I think about battery management.
