A 3.6 V set point is not a de-rated 4.2 V set point Both chemistries use the same four-stage profile: precharge, constant current, constant voltage, terminate on taper. Texas Instruments puts the CV point at 3.9–4.2 V for Li-ion against 3.5–3.65 V for LiFePO4, with precharge thresholds near 3.0 V and 2.0 V respectively (LiFePO4 […]
