Can you reproduce this? It definitely shouldn't be happening, so make sure you had solar panels and not arrays. Also, what kind of cables did you use, and was this in survival?

Edit: What's this about a redstone engine? Also, I tested, and batboxes don't even destroy torches when they explode (which have a blast resistance of 0)
