1. A method of using second use batteries, the method comprising:
communicating an external load demand to battery management modules (BMMs) of first use batteries and second use batteries;
communicating, by each of the BMMs, the state of health (SoH) of the respective first use battery or second use battery to the other BMMs;
by the BMMs of the first use batteries with a highest SoH, engaging the first use batteries to meet the external load demand, wherein the highest SoH is determined by the BMMs by ranking the SoH of each battery relative to the other batteries; and
by the BMMs of the second use batteries, setting a discharge limit for each of the second use batteries based on the SoH of the respective second use battery, and controlling the second use batteries to supply currents not to exceed the discharge limits of the respective second use batteries to load-share with the first use batteries.
