Tomáš Klouda Whydo you give so high amount of stars when you are disappointed and it doesn't work for you? :-O

Tomáš Klouda Unless you have different version than everyone else, there is no need to unscrew the battery holder. You just swivel that small lever under the screw to remove it.

Tomáš Klouda I am sorry, but you obviously didn't read the description, as there is not a single word about it being shipped with or containing battery. It ships with two cables with standard DC connectors on them. The barrel one is used on laptops and LED lights and the yellow one on majority of hobby batteries, as this is targeted on hobbyists. So together with USB-C PD you have three ways to power it, but you are still complaining 😮 There is even image in the description showing it connected to hobby battery using that XT-60 connector.

Tomáš Klouda Did you really try to power it from your PC? 😮 Than consider yourself lucky, you didn't burn your PC. You need source capable of delivering 60W and USB port on your PC is definitely not built for something like that!
