That’s close to what I paid for my Nucleus nano. I just read the specs and I’m not much in favour of the built-in battery of the hand controller and it doesn’t say whether it can be powered by an external source. Tilta also says that the Nucleus Nano hand controller can’t be powered via USB, but it can.
I was digging this, until I saw the amount of power the motor requires. For gimbal use I don’t see this working out too well.
Not having an external battery for the controller isn’t the greatest, but you can probably use a portable 5v usb powered brick to keep it running if it dies. Definitely a great affordable option, though.
