I am a Chinese DJ，I installed four 12V battery packs on Numark Mixstream Pro for the first time in September 2022, and the handle has been working well, with a battery life of 7 hours. Considering that the four battery packs have separate protection boards and will charge and discharge each other, I recently changed to using a set of 6 21700 batteries, three in parallel and three in series, battery capacity: 9800mAh, and added a 12V voltage regulator module and a separate power switch, because Numark Mixstream Pro will lose power when in standby. Now my Numark Mixstream Pro has a battery life of 12 hours, and it has perfectly participated in two outdoor performances.

Nice mod, where did you plugged in the voltage regulator? To the board somewhere or did you soldered to the main power input?
I connected the voltage regulator module behind the battery pack, the battery pack to the voltage regulator module, and the voltage regulator module to the controller power interface, so that there is a continuous 12V voltage

Awesome mod having it all internal. On my Roland controller I use a CAT car jumper battery and it lasts longer than I have ever played for.
