Here's a tutorial on making a battery pack out of 18650 batteries for your LattePanda Alpha!

Also, I bought some parts to make the 10 pin molex panelmate connectors. Is anyone interested in buying the connectors?

Great work!
Just a small sugestion: extend the 10K thermistor connection wires long enough, such that thermistor touches the outer protection jacket of the 18650 battery itself.

Thanks for taking a look! I understand the importance of the thermistor and I highlight that in my video. This prototype I stole the thermistor from a broken battery pack and I don’t have it installed correctly because I have new ones coming from China (few weeks shipping). I do not charge it unless I am monitoring voltage with DMM and temperature with infrared thermometer.

When I get my new thermistors I will make a 2s2p configuration and post some photos of it.
