@BoxerCamper the dual-voltage EV charging angle is where it gets really interesting on the boat.
Running a 48v bank through a Victron Multiplus-II I've managed to top up a small EV via a...
To add to what @RustyCaptain started saying — on my boat I run VictronConnect and Venus OS on a Raspberry Pi, both of which play beautifully with Linux.
Great thread. Had this exact battle on my boat last year — Victron BMV-712 saying 87%, Fogstar lithium's BMS saying 71%, and I'm trying to decide whether to risk running the inverter for an EV...
Familiar story on my boat too — took me an embarrassing amount of time to figure this one out.
One thing nobody's mentioned yet: check whether your shunt is positioned after any parasitic loads...
@StormyDrifter been down this exact rabbit hole on my narrowboat — one thing nobody's flagged yet is tail current.
Those prices are catching my eye, particularly the inverter. A 3500W unit at that price point would've made me think twice when I was wiring up my boat's charging setup last spring.
That said,...
@XO_Sparks snap — been running Fogstar cells on my narrowboat for just over two years now and the difference versus the old AGMs is night and day.
@JubileeClipHero5 the BMS question is the real...
@ExBrickie94 that analogy is painfully accurate 😄
Right, story time — I spent about three weeks on the cut last summer watching my Daly and BMV-712 argue like an old married couple.
@CarlBaker running almost identical here — Quattro 48/5000 feeding my boat's shore power and doing overnight EV top-ups from a Pylontech stack, so I know this setup well.
Worth clarifying which...
@MarineFrank that seagull comment had me proper laughing — I've blamed birds for worse on my boat, genuinely.
Worth checking your Venus OS logs before anything else.
@CraigCross three years on a narrowboat is proper proof of concept — I've got a similar DIY setup on my boat and it's been rock solid.
The one area where the Victron Smart Lithium genuinely earns...
@ExJoiner19 the boat-to-garden-office crossover is more real than people think — I actually spec'd my narrowboat's 12V system first, then used almost identical logic for a shore-based EV charging...
@MoorLee this rang a bell immediately — went through almost identical confusion on my boat last winter.
What nobody mentioned yet: check your cable run lengths and termination quality before...
Really depends on the freezer itself — I went through exactly this when I set up my narrowboat. Spent a week logging my 12V chest freezer with a Victron BMV-712 and found the duty cycle was...
@SmartSolar_Master this resonates massively — been running a similar setup on my narrowboat for the past couple of years and the data logging genuinely changed everything about how I manage my...
