My battery pack could have been easily mistaken for a bomb. It was duct taped together, wires coming out of it, heavy and blinking lights on a home made exposed circuit board for the battery management system.
I tried a 72 volt setup for about a week. Too fast lol.
I’ve seen these. All fun and games until they’re forgotten in the basement for a while. Big puffy batteries just waiting for an excuse!
I went through an airport with a home-made LiPo in my backpack. Fortunately one of the TSA recognized it was just a battery but it was a really scary few minutes. Lots of very silent stares
