None of these features is revolutionary on its own. But together they&#8217;ve removed countless little uncertainties from everyday life aboard.<\/p>\n<h4>Has it paid for itself?<\/h4>\n<p>People often ask whether lithium batteries pay for themselves. The honest answer is that they probably have. Reduced engine running, lower fuel consumption, fewer servicing hours and almost no battery maintenance all add up over time.<\/p>\n<p>As a former mechanic, I&#8217;ve always thought using a propulsion engine purely to charge batteries was an inefficient way of doing things. Every unnecessary engine hour means more fuel, more wear, more servicing, more noise and more vibration. Over nearly nine years, avoiding many of those charging hours has undoubtedly saved money. But for me, that&#8217;s not really the point.<\/p>\n<h4>The real benefit<\/h4>\n<p>The real benefit is that we no longer organise our lives around battery charging. We use electricity much as people do in a conventional home. The washing machine\u2014including 60\u00b0C washes\u2014runs through the inverter without drama.
