@Nobby43 classic cliff-hanger — assuming you're seeing cutouts under heavy load, first thing I'd check is your battery connections and cable sizing.

@RhysGrant — classic cold lithium behaviour. BMS cutting out under heavy load is the likely culprit, not the Multiplus itself. Most lithium cells (Fogstar Drift included, from my own painful...

Reply by @Gazza24: Great thread @TracyGrant! I've been doing something similar with my setup in Yorkshire.
Picked up a "30A PWM" controller off Amazon for about £12 last spring to run a small 200W panel on my shed setup. Seemed like a bargain at the time.

Just converted my motorhome to a 200Ah Fogstar Drift LiFePO4 and now I'm helping a mate sort his narrowboat.

My tiny house runs almost identical — except I made the rookie mistake of undersizing the inverter first time round, so now I've got a Victron MultiPlus sat where a much cheaper unit should've...

I'm looking at fitting a DC-DC charger on the boat to top up a 200Ah lithium bank (Fogstar Drift cells) from the engine alternator when we're cruising.

Reply by Finn1975: @BorderCamper — worth mentioning that you can set up custom alerts per installation on VRM, so you can have different notification thresholds for the van versus the boat.

Mine's sat in the motorhome reading 87% SOC but the lights are already dimming — classic sign the Fogstar 100Ah LiFePO4 is actually closer to 40% in this 2°C overnight nonsense we've been...

Running almost exactly this on my 57-footer — Multiplus 12/3000 rather than the 1600, but same SmartSolar 100/30 and a pair of Fogstar Drift 100Ah in parallel.

PikeSeeker | 847 posts @DailyDream I kept both in my Sprinter conversion for about six months before ripping the relay out entirely.

Been going back and forth on this for weeks and I need a sanity check from people who've actually done it rather than YouTube influencers trying to flog kit. Setup I'm planning: 2x 200W panels on...

Gibbo53 | 67 posts This is exactly what I've been worried about with my tiny house build — I'm planning a similar EVE cell setup and hadn't really thought about winter charge cutoffs properly.

Pricing up a 100Ah LiFePO4 for my Transit connect conversion and the difference is doing my head in.

Picked up 8x 280Ah EVE cells from Fogstar last month for the cabin build and genuinely had to stop myself ordering a second batch "just in case" — the price per kWh is almost...

CliffSpirit | 203 posts | ⚡ Off-Grid Enthusiast Worth flagging something nobody's mentioned yet — your Multiplus-II 5000 is rated at 48V, so it'll only deliver around 4.5kW continuous to a Type 2...

Great shout from @HazelChild on the connections — I'd add that it's worth checking the actual contact surface area on those bus bars too, not just torque.

@SimonJohnson67 — coming from the narrowboat world myself, I'd say the mindset transfers pretty well actually.

Not a motorhome user but this is directly relevant to my garden office setup. Running a Fogstar Drift 100Ah and I was shocked last winter when I checked the BMS app first thing on a cold morning —...

The real headache wasn't the cells — it was convincing my Victron Multiplus that a £380 battery deserved its respect, but once I tweaked the charge profile it's been smoother than my narrowboat's...
