Why do we want more balancing current from a BMS?

Want to build a portable Charger

in my experience throwing a 3v and 4v 30Q cell together in parallel maybe increased the heat by 5 degrees F. MAYBE you could just throw the two in parallel when the one on the board is dying. [image] I did the math based on ohm’s law and assuming this 30Q resistance and 10s3p [image] here’s how MY math goes and maybe someone can correct it: first finding the resistance of the 3 cells in parallel would be 1/.034 + 1/.034 + 1/.034…and keeping it simple lets call it 1/.1, so answer being .01 f…
