MixPre-6 LiPo Battery Backpack

Here’s my DIY solution to powering the Sound Devices MixPre-6 audio recorder. The official “L Series” battery sled (MX-LMount) works great, but I wanted something to meet my specific use case. It’s a flat “backpack” that hooks under the MixPre via claws on the front and back, with a short wiring harness that connects to the existing 4xAA battery sled on the back of the recorder.

Updated to v2 (June 03 2020): New side cleat (mixpre-batt-side-cleat-v2(print2x).stl) is more durable and has larger hook end so recorder can stand on it’s end without falling over from the offset weight of the battery pack.
