Regenerative braking captures kinetic energy during deceleration and feeds it back into the battery, but its overall efficiency seems to vary a lot between setups. I'm trying to understand whether the limiting factor is primarily the battery's chemistry and its charge acceptance rate, or if the motor/controller's algorithm and hardware play a bigger role. How do these elements interact, and what typical trade‑offs should we expect when tuning for maximum energy recovery? Would love to hear experiences or references.
Does regenerative braking efficiency depend more on battery chemistry or motor control?

I’ve found the battery chemistry usually sets the ceiling – my Lada’s Li‑FePO4 pack stopped accepting current above ~30 A, so even when I tuned the controller for a more aggressive regen curve the extra energy just got rejected as heat. In practice you can squeeze a few percent more out of the motor/controller, but the real limit is how fast the cells can absorb the charge.
