Setup
I 3D-printed one of these cases to use with a XIAO nRF52 / SX1262 Meshtastic node.

However, the 18650 3.2V Li-ion attery I have is unprotected and I want to be safe, so I bought battery protection boards:
10pcs 1S 3.7V 3A li-ion BMS PCM battery protection board pcm for 18650 lithium ion li battery https://a.aliexpress.com/_mr9W3lj
I soldered the battery contact pieces to the B- and B+ of the battery protection board. Then I soldered the P+ and P- to the BAT + and - on the Xiao NRF52840. This video mostly sums it up.
Question
I know this may be pedantic, but I know my limits and would rather get things right. Before I put the battery in, I want to confirm:
- Is this design safe?
- Are there ways I should test the design first?
- I used whatever cable I had laying around, but is there an ideal gauge to use from Battery->Xiao and from Battery->BMS?
- Are there recommended ways to improve this design such as a fuse?
