Hi, I work at an equipment checkout where we loan a number of Arri-S cameras. Currently we use them with Smith Victor 12V battery packs. The problem with them is that the re-charging power supply will light up green before the battery has reached the necessary >4.5As needed to run those cameras. I would love to have something that my student workers can easily recharge and know it's charged enough for our needs. Are there other batteries y'all have worked with that come with 4-pin XLR (or can be easily modded) that give better feedback? Best, Lev

Hi, I work at a teaching facility where we have six Arri-S kits with matte boxes. We've been able to maintain all the equipment for a very long time, but one thing we're running out of and can't seem to find are the trays that hold the 2 x 2" filters. We're down to one per matte box, instead of the two they can hold. Does anyone know where I can obtain more? Or is there a relatively sturdy DIY replacement? Could a holder be 3-D printed? Thanks for any advice! Lev
