Google Mini Rechargeable Battery Pack

thingiverse

I set out to create a custom battery pack for my Google mini, one that I could easily recharge and take with me on the deck or wherever else I wanted to go. After finding the original design by Hopo28, I decided to put my own spin on it and see what I could come up with. To make things easier for others who might be interested in building their own pack, I included a detailed spreadsheet with all the necessary parts, wire lengths, printing times (which varied depending on my Snapmaker equipment) and other important details. When printing the covers for the circuit boards, I opted to print them in quantity and added a raft to ensure the best possible quality for my setup. Only the charging circuit board is glued down, and I took extra care when assembling the voltage amplifier by applying a small drop of glue to prevent any potential changes to its 5V value. Using an earlier version of this design, I was able to get around six hours of battery life at 75% volume. I made sure to design the pack with replaceable batteries in mind, which also made it easier to ship via ground through the US Post Office (I simply had to remove them first).
