The -mv suffixes I deciphered to be tuned settings for various aging levels. The BYD vs TMM batteries on Akari have a different capacity, and public spec sheets match neither :) BYD says initial capacity = 3056000 uAh TMM says initial capacity = 3217000 uAh the spec sheet says 3180 mAh, so presumably the TMM one was used in all models The constant current charge threshold is set to 4370 on the -4380mv bin and the DTs don't clearly specify a lower bound (maybe in the qcom,fg-data blob?), but 3.4 sounds appropriate Konrad
