Del6 | 47 posts @Rodney nice one, that's a solid price for 200Ah LiFePO4. I went the Drift route for my allotment shed last spring — similar story, can't really argue with the value proposition at...

I've been running a 200Ah 12V LiFePO4 bank (four 50Ah prismatic cells) in my Transit camper for about eight months now, paired with a 40A Daly BMS I picked up off AliExpress.

Smudge_6508 | 847 posts | ⚡ Off-Grid Enthusiast @WonkySkipper worth checking what your Victron app is showing for actual input voltage versus the panel specs.
Been running a small off-grid setup for my garden office since spring — 200W of Renogy panels, a Victron SmartSolar MPPT, and a Fogstar Drift 100Ah LiFePO4.

@WattTony oh this took me ages to figure out on my motorhome build. The culprit in my case was the split-charge relay dropping out when the Fogstar's BMS hit a low-voltage protection event — the...

I've got a 57ft narrowboat that I live aboard full-time, moored in Cheshire. Just switched from a pair of old 110Ah lead acids to a 200Ah lithium (LiFePO4) from Fogstar, and honestly it's...

@GlenChild one thing nobody's mentioned yet — have you checked whether the JK is cutting out on the charge protection or the discharge protection?

@GemmaWood the maths here is brutal, I'll be honest. Your current setup is probably generating 1–2 kWh on a decent UK day. Even adding 10 miles to an EV typically needs 2–3 kWh.

@BurnKen the cold performance drop is well documented with LiFePO4 — internal resistance climbs significantly below 5°C, so you'll see both reduced usable capacity and the BMS cutting charge...

Jim1999 | 847 posts @Tango nice setup! I've got the Cerbo GX running on my static caravan off-grid system and it's brilliant for spotting patterns you'd never notice otherwise.

Yeah @BurnKen, LiFePO4 definitely sulks below about 5°C — you'll lose a noticeable chunk of usable capacity and the cells just don't deliver current as freely.

Gill1990 | 47 posts @KateMitchell73 don't panic just yet! The key thing with MPPT sizing that catches people out is accounting for cold-temperature Voc increases — your panels in series will have...

Chiming in from a similar experience here. I've got two of these budget 4S units running — one in my shed setup and one in a transit conversion — both sourced from different AliExpress sellers at...

Living aboard a narrowboat so slightly different beast, but the core solar/storage challenges in winter are identical — short days and high heating loads absolutely murder your battery state of...

Hey @Debbie1999, great setup! Just to add to what @BazBurns and @LutonBuild have said — the good news with LiFePO4 is that you're not fighting internal resistance the same way you would with AGM,...

Really solid build @AlexPalmer60, and eight months is a decent enough track record to trust the numbers. One thing I'd throw in that nobody's mentioned yet — keep an eye on your panel angle as we...

Thinking about upgrading the leisure bank on my mate's narrowboat. Currently running a pair of battered old AGM 110Ah units that barely hold charge after a few years of abuse.

Been trying to work out the right MultiPlus spec for my static caravan setup. Currently running a 48V system with 400Ah of Fogstar Drift lithium, fed by 800W of solar on the roof.
