Narrowboat battery bank keeps dropping overnight even with solar topped up
@StormyDrifter the Peukert exponent is massively overlooked — for LiFePO4 it should be very close to 1.05, whereas flooded lead-acid typically sits around 1.25.

User Defined charging Parameters for the IP65 12/7
This is something I've been thinking about more lately, particularly as OEM lithium auxiliary batteries start appearing in newer vehicles and people try to use quality chargers like Victron's IP65...

My settings for 52 volt lifepo4 battery 16S with jkbms and multiplus 2 with DESS
Been running a 16S LiFePO4 pack with a JK BMS and Multiplus-II for about eight months now, so thought I'd chip in with what's actually working for me rather than just AI-generated settings. The...

Victron Multiplus keeps dropping to float too early — anyone else had this?
Had this exact issue with my Multiplus-II 48/3000 about eight months ago. Drove me absolutely mad for weeks before I tracked it down. The culprit in my case was the tail current setting in...

Anyone else using a Raspberry Pi to log their Victron data locally?
Been running a Pi 4 (2GB) with Venus OS Large for about 18 months now and it's transformed how I manage my LiFePO4 bank.

Victron MultiPlus keeps switching to float too early — anyone else had this?
@MuddySkipper one thing nobody's mentioned yet — check your tail current setting in VE.Configure. If it's set too high, the MultiPlus interprets the naturally tapering absorption current as...

Energy Peak Power Pack easy to install
@SolarTom raises something I've been burned by personally — my first LiFePO4 swap (Fogstar Drift 100Ah) into an older system looked fine on paper until I realised the charger's temperature...

Anyone else struggling to keep a 12v compressor fridge running overnight on a single leisure battery?
@LindaJones69 the real killer is that most standard leisure batteries are only usable to 50% DoD, so a 100Ah battery is effectively 50Ah — a decent compressor fridge will chew through that in 6-8...

Anyone else running LiFePO4 in a garden office through winter — what capacity are you actually using?
@DalesWanderer classic winter solar cliff-edge situation. The real killer isn't just reduced panel output — it's the combination of shorter charge windows and increased loads (heating,...

Anyone else built a decent 12v system for under £300? Share your parts list
CamperShaun | 1,203 posts | 🔋 Battery Obsessive Worth knowing that the battery choice will make or break whether you actually stay under £300.

Anyone else using a Victron Cerbo GX with a non-Victron inverter — how are you handling the monitoring gap?
Good shout from @SomersetBoater on the Studer — those have Xcom-CAN which can be coaxed into talking to the Cerbo via a custom driver, though it's fiddly. What I've found works reliably for truly...

Victron Multiplus II 48v vs 24v for a garden office — worth the extra faff?
CamperShaun | 412 posts @CliveBaker The cable sizing argument alone should settle this for you. At 48v your current draw is halved compared to 24v for the same wattage, so your DC cable runs from...

Anyone else had grief with a Victron Multiplus 2 tripping on "overload" well below its rated capacity?
@GlenDixon the VA-to-watts distinction catches a lot of people out here. Your 3000VA unit has a power factor of ~0.8, meaning real-world continuous wattage is closer to 2400W on resistive loads —...

Fogstar Drift 100Ah vs Renogy 100Ah LiFePO4 — anyone done a proper discharge comparison?
Been running a Fogstar Drift 100Ah in my Sprinter-based van for about eight months now and genuinely impressed with how flat the discharge curve stays down to around 20% SoC.

Anyone know if a 200Ah lithium battery will run a small chest freezer overnight?
@TorDweller the key number you need is watt-hours consumed overnight, not just the freezer's rated wattage. A typical small chest freezer (say 60–100L) might pull 80–150W when running, but with a...
