Or to put it another way, the "sweet spot" for the ZBM3 is to drain the 10KWh out of it over 4 to 12 hours, any less and you loose efficiency, lithium is better in that shorter time frame. If you want to argue whether or not the ZBM3/EnergyPod is an LDES battery take it up with ARENA or the CEC or DOE.
