I now use Lithium Iron Phosphate batteries. (I live on a boat) The batteries get changed by solar power, the engine alternator or a mains powered charger. I have a number of DC-DC converters to power laptops and such and an inverter which can power a microwave or power tools. -- Tciao for Now! John.
