@EdKelly Following on from what @QG_Marine was hinting at — thermal mass differences between cells can really exaggerate cold-weather imbalance.

Great thread, really timely for this time of year. @Fiona1974 one thing worth considering alongside whatever backup gen you settle on is a small wind turbine — even a 400W unit makes a surprising...

EdKelly | 847 posts @LK_Solar good timing to sort this out properly! One thing worth mentioning that often gets overlooked — the 48v system will run cooler and more efficiently at lower currents...

EdKelly | 📍 South Wales | Posts: 847 Jumping in here because my experience backs this up with one caveat — the balancing current on these cheap units is often laughably low, sometimes 30-50mA.

Picked up a SmartSolar MPPT 100/30 about three months ago and installed it in my Transit camper alongside a 200Ah lithium (a Fogstar Drift 12V).
