PCBA procurement and/or manufacturing

[0xjairo]

Hello, first of all, very cool and interesting project!

I'm interested in making a BMS-C1 PCBA for use at work, for internal testing. I'm interested in characterizing Li-ion batteries that we use in our systems, specifically interested in the health/capacity of our batteries (we have dozens of batteries). As you may imagine the batteries that we have in circulation have a pretty wide range of charge cycles and more generally, age/capacity. These batteries are installed/removed from our deployed system through the course of the day (multiple battery cycles per day) and also in every day development.

The batteries that we use are commercially available and are charged with a commercial charger but as the age of our batteries increases, we'd like to understand their individual capacity and/or health.

The BMS-C1 looks like a good fit for running capacity tests, coupled with an electronic load and software tools collecting data.

Questions:

• Has the BMS-C1 been used in a prototype or production system? I'd like to understand how usable it is in its current state.
• What version (tag or commit) of the hardware is best for making a PCBA
• Do you use a contract manufacturer for fab/component procurement/assembly? Ideally we can get a fully assembled PCBA (turnkey) from a manufacturer, but have no issue assembling in house.

Thank you for your time!
