I have a Arri 16BL but the battery is missing. I know I need a 12V battery and a XLR-4 cable to power up my BL. Below are the images of my BL. Can anyone tell me where I can get these items please? https://ibb.co/qnjtqSc https://ibb.co/n7rsxry

Hi, I need the service manual as well. Would anyone send it to me via foneboard@gmail.com My name is Kam. Thank you so much,??
