Re: connections for? EcityP Smart S5-13 BMS

hello guys, You'r all doing nice reverse engineering with this terrible OZ which is so difficult to get litterature about! As of my understanding the bleeding strategy is quite well done, based on voltage delta between cells. However it may have a drawback. If for some reason one cell has a higher c...
