Been through this exact dilemma myself when I put together my cabin setup about two years back.
I went with the Victron Smart BMS in the end, paired with a 280Ah Fogstar Drift bank, and honestly I've never regretted it. The ecosystem integration is what sold me — everything talks to each other through VE.Direct and Cerbo GX, and you can see exactly what's happening with your cells from the sofa on a January night when you really don't want to be trudging outside.
The Daly is a perfectly capable bit of kit for the money, don't get me wrong. Plenty of people run them without issue. But my experience is that the Victron BMS gives you far better visibility into what's actually going on, and the balancing behaviour feels more... considered? Less aggressive when temperatures drop, which matters up here in winter.
The price gap is significant — roughly £150 vs £400+ depending on the spec — so I understand why people hesitate. A few things I'd ask yourself:
- Are you running other Victron kit already? (If yes, it's almost a no-brainer)
- How remote is your setup? The monitoring peace of mind has real value when you can't pop out to check things
- Are you planning to expand the bank later?
If you're starting from scratch on a tight budget, the Daly gets you going. But if you're building something you want to forget about for years at a time, the Victron investment makes sense to me.
What inverter are you pairing this with? That might change the conversation entirely.
