Welcome to our anonymous survey! The Sons of Battery were founded by too much weight on our ribs and we now have a considerable reach and impact. Since I am asked relatively often about system weight, including by manufacturers, I would like to collect some data! In order to be able to answer more well-founded, perhaps also to be able to make a difference in the minds of some manufacturers (as I said, anonymous & voluntary)
7 questions without thinking, it takes less than 10 seconds, but it helps us enormously!
