> the limitation is in the amount of power that can be pumped into them You could say that. You could also be more pedantic and say that this comes at the cost of some decrease in battery life (and efficiency) due to the resistance resulting in some amount of heat in order to facilitate this high-speed charging process. But I don’t know if the ROI on improved battery life would be worth the complexity, size, weight, and cost of a two-stage charging process. As battery tech improves, that resistance continues to come down.
