Thanks, julesa! I had missed that the BMS also controls the charging source. D-oh! I just looked at the schematic again and it's making sense now. The return side (-) of the charger has to pass through a power FET which is switched according to the charge level of the pack.

I have a question that I can't seem to find the answer to. If you considering a series string of 40AH LiFePO4 cells, the charging current for such a pack is going to be in the 10A to 20A range. The BMS being discussed here will only shunt 1/2A, leaving the rest of the charging current to go...
