Video - Eneramp battery and Little Rosie, replaces Battleborn and Victron

Stumbled across this video last night and it's got me thinking. The Eneramp setup looks genuinely tidy — especially the way Little Rosie handles the BMS and comms in one compact unit. Reminds me a bit of when I first switched over from my old lead-acid bank to Fogstar Drift cells; that moment where you realise the whole system suddenly makes sense rather than being a pile of compromises held together with fuse wire.

What's catching my eye is the claim around drop-in simplicity versus a Battleborn setup. I've got a Victron SmartShunt and a Cerbo GX in my garden office system, and honestly the integration side of things is what keeps me loyal to that ecosystem. The question I keep asking watching this is: what does the comms story look like for Eneramp with Victron kit? The video's a bit vague on that.

Has anyone here actually got hands-on time with one? I'm curious whether:

• The BMS data is genuinely accessible or just locked away on a proprietary app
• How it behaves under real UK winter conditions (I'm in the north, so cold discharge is a proper concern)
• Whether Little Rosie handles multi-battery parallel configs cleanly

I'm not in the market right now — my 280Ah bank is doing the job for the garden office loads — but I could see myself revisiting this when it's time to expand. The Battleborn price point always felt steep for what you were getting, so if Eneramp can genuinely challenge that with better integration, that's worth following.

Would love to hear from anyone who's taken the plunge.

Compact BMS unit with comms built in sounds great until it's the one thing that bricks your whole system at 11pm on a Bank Holiday weekend 😅 — my Victron setup at least lets me argue with individual components when something goes wrong in the static van.

@HeatherWalker that's every BMS ever made, to be fair — at least Little Rosie sounds like she'd apologise nicely before taking the whole van down with her.

@DaleLover fair point but there's something to be said for having a known failure mode with established support. My Victron setup has thrown fits at stupid hours too, but at least I've got a community of 10,000 people who've seen the same fault code.

Eneramp looks interesting on paper. Probably fine. But "looks tidy in a video" and "survives three winters in a damp shepherd's hut" are very different things. Battleborn and Victron aren't cheap, but they're proven in real installs, not just YouTube thumbnails.

How long has Eneramp actually been trading? Genuine question — I couldn't find much history on them. That matters more to me than how compact the unit is.

@SaltyHiker raises the point I'd push hardest on — support longevity. Victron's ecosystem has been around long enough that even obscure firmware bugs are documented somewhere on the community hub. With a newer unit like Little Rosie, you're essentially beta testing on your actual installation.

That said, I've got a Fogstar Drift 200Ah paired with a Cerbo GX in my garden office setup, and the BMS comms integration was genuinely painful to get right initially. If Eneramp have baked that all into one unit cleanly, the concept is sound.

My concern is what protocol Little Rosie speaks — if it's proprietary rather than CANBUS or RS485, you're locked in permanently. Anyone dug into the technical spec sheet rather than just the marketing video? Datasheet transparency would tell you everything about whether this is a serious contender or a pretty box.
