Hi poviliukas20,

What is kind of the batteries do you use?
The power specification for Orion board is input: 6~12v.
According to our test and research, it is suggested to use rechargeable Li-ion battery or rechargeable nickel-metal hydride, nickel-cadmium which can be bought from amazon or local shop. Or Alkaline battery with good quality like Energizer, DURACELL.
Please kindly change the batteries have a try.
