I have (280 qty) LiPo 7.4v2S w/BMS modules. I am wondering if it is advisable to put these in a 40P7S configuration with a 7S BMS on top "OR" break each 2S pack apart and remove the module level BMS then do a 3.7v 80PS7 configwith a 7S BMS? I'm a beginner and have been trying to learn from all you folks, but I've not been able to find anything about BMS on BMS interactions. I'm attempting to make a portable solar generator. Any help would be greatly appreciated!
