You just could balance those packs where the cells are connected in serial. Paralled cells canīt be balanced.
But itīs not the case just for this saddlepack 1S Lipo above. There are a lot of 2S Lipo available what have 2, 3 or even 4 cells paralled also. I think 2 cells paralled isnīt a big problem but Iīm staying away from packs with 3 or even 4 paralled.
