![]() ![]() You’d probably be surprised hell, I was when I did the research for you good folks. It doesn’t take a genius to realise that one tiny spark… and the whole thing will go BOOM!ĭoes anyone still remember the Hindenburg? Hydrogen gas at work… Photo: Universal History Archive Surely it can’t make that much hydrogen gas? All of a sudden you’re putting a bunch of 12-volt gear (charger, solar controller, Anderson plugs, ciggy sockets, etc.) in a sealed container that will fill up with hydrogen gas. Where this becomes a problem is when you go and buy a ‘sealed’ box or space-case. That’s why on the side of a lead-acid battery it says to store, use and charge in a ‘well-ventilated area’. So as soon as your charger goes over 14.1-volts (2.35-volts times six cells), it’s generating a hell of a lot of hydrogen gas. In our specific case, your 12-volt lead-acid battery has six cells. This occurs when your battery voltage goes above about 2.35-volts per cell. It’s actually hydrogen and oxygen (two parts hydrogen, one part oxygen – from water H20). Most folks probably realise that when you’re charging a lead-acid battery, it gives off hydrogen gas. ![]() Until of course, you open the lid! How exactly am I turning the battery box project into a bomb?! For the more scientifically minded, it’s essentially Schrodinger’s Box both a battery box and a bomb, at the same time. There’s only one problem: by using sealed boxes, you’re basically turning your neat DIY project into a bomb. I absolutely understand the concept behind them they’re portable, easy to plug-in, can be moved to the different accessories using them, and are a nice and easy DIY jobbie you can do at home. In a rather concerning trend I’ve noticed as of late, there are a lot of people building ‘battery boxes’. We really need to stop turning battery boxes into hydrogen bombs! ![]()
