    Li-Ion discharge limit circuit

    As i know - it is not possible to modify the cut-off voltage of those prot ic's. Just make a low batt warning light. :poke:OR you need light driver with cut-off.

    I made balancing circuit for my 2s5p li-ion pack by my self, but i used protected cells for this pack, to be shure not to drain them too mutch. I used balincing circuit because, if using only protected cells or pack with pcbs from them, the overall available pack capacity will drop after each...
