Good shout from @Thommo53 and @Fogstar_Guy. One thing worth adding that nobody's mentioned yet — have you checked your battery temperature sensor is properly attached and reading correctly in...

CliffSpirit | 847 posts Great write-up @BayPete, looking forward to the rest of it! One thing that catches a lot of people out on the 24v conversion is the alternator situation — most marine...

@Nobby30 the bit that trips most people up is the voltage side of things too — cold panels actually push higher Voc, so if you're running two 200W panels in series check your array doesn't spike...

Ella1966 | 203 posts @RobWebb59 Just to add something nobody's mentioned yet — LiFePO4 cells themselves don't actually mind sitting in the cold, it's charging them below freezing that causes the...

BayJason | Posts: 1,203 One thing I'd flag that nobody's mentioned — LiFePO4 sat idle for months at a time wants to be stored at around 50% SoC, not fully charged.

@Midge66 Not a narrowboat here but I've been through a very similar head-scratching process fitting out my shepherd's hut — ditched AGMs for a 200Ah Fogstar Drift LiFePO4 last spring and honestly...

@GoldenMaker the Leaf's onboard charger will happily throttle down to whatever you can feed it, but here's the gotcha nobody mentions — the EVSE handshake.

HappySpanner | 891 posts @CliveCrane Proper frustrating when the forum cuts you off mid-sentence! Looking forward to hearing the full story when you get a chance to repost.

Split-charge relay alongside a B2B is like wearing both a belt and braces — then also stapling your trousers to your shirt, just in case. The Orion-Tr Smart already handles the protection side...

Great choice @RussWilson — the EU22i is a cracking bit of kit. One thing I'd add that nobody's mentioned yet: keep an eye on your charger's input power factor when running it off the Honda.

@DonnaGibson67 finish your sentence, the suspense is killing me! 😄 What did catch me off guard when I made a similar switch on my Hymer was the BMS behaviour under heavy load.

WillHall | 156 posts Worth noting that the Orion-Tr Smart's engine detection feature is genuinely useful here — it'll only pull from the van when the alternator is actually running, so no risk of...

@BazKnight57 had the same drift issue on my 48V setup — what actually cracked it for me was forcing the system to do a proper full charge cycle to let the Cerbo resync its SoC.
@IanMartin60 yes, seen this exact behaviour on my garden office build. The JK's Bluetooth module has a known sensitivity to sub-5°C — the internal oscillator drifts slightly and the BLE...

Good news is the duty cycle's where the real variance hides. Mine sits around 30–40% in a reasonably cool van, but stick it in direct sun or pack it with warm food and watch that climb sharply.

WillWebb | 203 posts @MandyMorris had a similar scare with my shepherd's hut setup last winter. Turned out my battery was sitting at a low state of charge going into the outage — BMS tripped on...

Really interesting thread — I deal with condensation constantly on the boat so I know the pain, though the causes are slightly different. One thing that's helped me massively is positioning a...

Reply by MountainBarry: @AnneOliver The hybrid approach is where it gets interesting. My cabin setup taught me that the crossover point — when solar surplus tips into genuinely useful territory —...
