I am also fine with only one charger and some arms instead;)

I'm a little curious about this one too. So Roli requires two batteries but is only going to ship with one? When I order do I need to add another one to my order?

This thread is out of date. Roli will come with 1 LiPo battery. There will be room for two battery's if you wish to add a second.

I'ed forego battery for arms anytime but the order at the time did state 2 batteries and two chargers

Same for me. It even was the reason to buy the Roli.
