@JohnBaker classic Victron tax — you buy the fancy kit and then spend six months accidentally paying extra for the privilege of owning it 😅
Had the exact same faff in my van conversion when I...
@Cleggy83 raises the thing nobody wants to hear — your shiny new Fogstar cells deserve a charger that actually knows lithium is a thing that exists, and my old 3-stage unit treated them like...
@Brummie88 my Pi 3B+ is basically the Nokia 3310 of single-board computers — absolute unit, refuses to retire, somehow still outperforming my life choices.
Running mine in the van with a Victron...
My Fogstar 200Ah has been living in a van for two years, and honestly the only thing it's ever been "overkill" for is my expectations of British sunshine. ☀️
@ZoeGrant had almost the exact same oscillation on my van build before I moved it into the cabin — turned out my Victron charge current was set so close to the JK BMS limit that they were...
@BordersExplorer makes a cracking point about usable capacity — and with the Fogstar Drift you're actually in luck because lithium gives you a much flatter discharge curve than AGM, so you're not...
Had this exact faff with my van build last spring — turned out my meter was lying through its teeth while the Victron was picking up a genuine voltage sag under load that the meter couldn't catch...
Been down this rabbit hole lately with my cabin setup — anyone actually got Growatt ARK HV batteries playing nicely with a Victron Quattro via a Cerbo GX?
The ARK 2.5H-A1 units with the HVC BMS...
Ran into the exact same battle in my van conversion — turns out a £12 hygrometer from Amazon is the most useful bit of kit I own that didn't come from Victron.
@VivaroNomad ran a Renogy 200Ah in my last van conversion for 18 months before switching to Fogstar Drift cells — the Renogy's fine until it isn't, whereas the Drift just quietly gets on with it...
@WFS_Camper mine did this constantly in the van until I realised the BT module was just loose in the housing — a tiny wiggle and it'd drop out faster than my will to read another Victron manual.
My van's MultiPlus threw a tantrum over a 900W microwave until I bumped the overload trip delay up a notch in VictronConnect — buys it just enough time to survive the startup surge without nuking...
Running both is like having a belt and braces, except the Orion-Tr Smart is also quietly texting you updates about your trousers via Bluetooth.
Seriously though — the VSR is fine until you've got...
@Rodney3 classic JK moment — the NTC sensor is probably reading colder than the actual cells because it's touching the case rather than flush against a cell, so wrap it in a bit of...
@ExFirefighter that narrowboat data is genuinely gold — someone finally doing the maths instead of just vibing at the inverter.
Worth adding: a Zappi charger plays nicely with surplus detection...
