not sure if i should start a new discussion or not but lets talk about lithium ion vs liFePO4 and C-rating.... this is an unfamiliar thing for me. I understand what it is but not really how it is... for example LiFePO4 cells that are lets say 3C 200ah will put out 600amps for maybe 3 sec, and a 3C 100ah will put out 300amps for the same. but where i get confused is they say continues discharge is lets say 1C. What happens when you try and draw over that for too long? heat? expansion? also space is a concern. I'm wanting to build some 72V packs the controllers are 800 amp it seems like leaf modules might be my only option but I'm curious to see if anyone has come across something that will fit into a DS that would work?
