I’ve been owning a FP2 for nearly a year now. One of the first things I remarked was the lack of battery power. So a friend and me decides to find a way to put more juice into it.
The design is intended to:
- meet safety regulations by taking the hardware of an existing battery case for another phone
- Add heat sink capacity by including a 1€ coin above the CPU
- maintain one unique external USB port for charging (both battery and phone) and data access
- cost less than 50€ in total
We found a way with a KiwiBird battery case originally designed for Samsung Galaxy S7 (similar dimensions as FP2).
I just posted hte design on Thingiverse: https://www.thingiverse.com/thing:3414721

Feel free to share your ideas and comments! If there is interest, I might open a new thread to post more details about how we designed this…
