14 years of battery bank experience. Witnessed results of one fire involving 4 strings of L16s at 48 volts. Fire was confined to battery storage area. Not from an explosion but overcharging a dead string. On a personal note, I have seen and felt the shock wave from an exploding 8D 30 years ago. Hopped in a cabover semi truck to start it and the battery exploded under the open drivers door as soon as I turned the key. The metal lid of the battery box blew into the bottom of the cab and flew 75 feet and the concussion wave stunned me. I didn't know what had happened until I got a whiff of the sulfuric acid mist in the air. More effective than smelling salts. I bailed from the cab and hit the ground running. The top half of the battery had disintegrated into shrapnel. Never, ever, think there is not tremendous explosive energy in a battery. Nathan Jones Power Source Solar Inc. 417-827-0738
