@Adrian_Joachim

The protocol is somewhat standardized but the ec does expect certain batteries. The laptop side of the communication is actually open source, you can see how it talks to the battery

Anyone in this thread knows how to tune(or at least get accurate data) the battery pack? I ran into this problem and did a few tests but I don’t know how to read the BMS chip.
