When a lightning bolt struck Ben Franklin’s kite in 1752, it sent a direct current of energy to the key he’d tied at the end of the kite’s string. Ever since then, we’ve been looking at ways of generating, transmitting, storing, and using that energy — and modern human existence is now totally dependent upon it.
Our motorhomes, caravans and campervans are obvious examples of this dependence. They all need a source of electricity to function.
Even our gas appliances and diesel heaters are reliant on having some form of electrical power to ignite their burners. It’s therefore important to know how much 12 volt (V) energy your motorhome has stored before settling into a long stretch of freedom camping.
