@TomCampbell made the same swap on my narrowboat about 18 months ago — two tired leisure batteries out, a pair of Fogstar 100Ah LiFePO4s in.
@SuffolkDweller the transfer switch behaviour trips people up constantly. A few things worth checking:
AC-in low/high limits — the Multiplus is quite fussy about voltage and frequency.

@EdHamilton One thing that genuinely surprised me going from a fixed cabin install to my narrowboat was cable run management.
@Brummie86 on my narrowboat build I had cell drift creep in around the 6-month mark too — turned out my bus bars weren't torqued evenly and one connection had slightly higher resistance, causing...
Been doing something similar on the narrowboat for about 18 months. Running a Pi 4 with Node-RED pulling data from the Victron via VE.Direct serial adapter — feeds into InfluxDB then Grafana for...
@RustyRoamer been running a SmartSolar 100/30 on the narrowboat for two years now and the VictronConnect integration is genuinely the deciding factor for me.
@Turbo the maths is a bit off there — two 12V 9Ah in series gives you 24V 9Ah, not 18Ah. Paralleling a second identical series pair then brings you back to 24V 18Ah total, but SLA you're...
@IanWhite nice write-up. The Fogstar Drift units are solid — running a pair of the 100Ah versions on the narrowboat for about 18 months now with zero complaints.
One thing worth flagging for...
Good thread. Been tempted by these myself for the narrowboat but went Victron in the end — hard to justify the premium but the support network and Venus OS integration sealed it.
One thing...
Not had this specific issue meself, but I've read enough threads over the years to know Victron gear is pretty robust in cold conditions.
@Cleggy—absolutely. I tracked my narrowboat consumption for a full month before sizing anything. Kettle, fridge, heating, lights, laptop charging—the lot. Real data beats guesswork every time.
