Here's a rough example for a lfp: at 13.3v the state of charge is approx 90%. Turn on an 1200W airfryer the voltage drops to 12.4v (at…

an inverter will add 5-10% or more, so if the appliance requires a sustained 1250w the battery will be supplying > 1300w. That'd make it…

Yep, out of the box it's annoying. Takes a couple of mins to fix though, almost zero difficulty. End up with reliable, fine control over…

bamzero is correct about the update. Also, the 75/15 mppt maxes out at approx 220w for a 12v lfp, 440w for a 24v lfp. Over provisioning the…

If you can view cell voltages (crack this battery open), balance the cells, keep the cells between 3-3.6v, never charge when battery temp…

I'm happy if anyone finds "Stand up straight with your shoulders back" and it's ilk helpful. I'm not gonna argue. But I'm gonna be cheering…

I have the voyage and the previous paperwhite 212dpi. The differences are minor nevertheless real, e.g. better screen contrast, better…

Can't say exactly how long is battery life - I mostly use on ac - but have used for 8h+ on cheap $5 worth of alkaline D cells: lcd still…
