I've worked with my brother on building powered battery units for other equipment like cordless drills and so on. It can be done and done well. I'm glad to see you work this problem. I was thinking of attempting this with one of our worn out batteries so we can reuse the battery Protection Circuitry. This may help with the battery check. Good hardware hack.zuberio wrote: ↑Fri Jan 18, 2019 10:04 pmI built 2 powered battery units for my group's BLK360s. Considering the amount of scanning we did with them it really saved the field team a lot of frustration from having to wake up every 2 hours to swap a @#[email protected]$ battery. I used an eBay DC-DC step down converter with an old laptop power brick + a 3D printed BLK battery shell in order to make things happen. One caveat is that you need to use v1.4.1 of the BLK360 data manager and immediately start downloading a file before the data manager checks the battery state. You'll notice I do this in the below video - just do it off the bat and cancel, this side-steps the battery state check in this version of the data manager.
Here's a video I made demonstrating the hardware hack.

We've since traded in our BLKs for an RTC. Thus, I have the 2 powered battery units available if anyone is interested.
