Hi all, I'm wondering about the feasibility of building a rather high voltage 18650 battery pack.
would need to be 670v and around 30a although only looking for 5-10 min of capacity. I'm thinking this isn't really feasible but currious what thoughts people have? Aside from the obvious high risk and related danger from that voltage level and power capacity I'm wondering what would be the other major issues? From what I've researched it would seem I likely need two cells in parallel with around 180 pairs in series, and that series cells need balancing circuits, I'm suspecting accomplishing the balancing for that many cells would be the main difficulty as well as the risk for a cascading failure?
