You guys are missing the point of my original question. If I use a fireproof container for charging at home, I certainly would also in my truck. Make no mistake, I don't want my Lipo's to burst into flame regardless of where I am charging.

Let me clarify my question. I am referring to the safety of the charger and the battery. In other words, when a vehicle is not running its battery has a nominal voltage of 12V. When you start the vehicle that voltage jumps to approximately 14.4V. I am asking whether this change in voltage will damage either the charger or the battery. I have heard from one source that it may damage the charger but this person is not someone I would consider to be an expert, or even knowledgeable on the subject so I thought it would be a good idea to ask those who know.

Thanks for your input,

Brian
