Lithium Battery Pack

With 4 parallel sets of 3s you''d have 4 BMSs and only make parallel connections at the ends of each series chain. Of course this is an expensive solution but it has to be considered as viable if the cost and risk warrant it. If the cost and risk don''t warrant it then just parallel 4 batteries and hope for the best with a single BMS.
