Battery Management System -> cells balanced to different voltages
« on: September 29, 2012, 06:31:19 PM »
Hello All,

I've just tested my 48V BMS... After charging the whole pack, I measured the voltages on each cell... Part of the cells (the first 8 cells from 1st to 8th cell) were balanced to 3.5V each one, but the next 8 cells (from 9th to 16th cells) were balanced to 3.3V. Could someone explain this phenomena? Should it be so balanced or this is a problem with BMS? The cells are identical.

Thank you!
