I read an ESP runs at 20 uA in deep sleep mode. Assuming this is true...
Take the capacity of one LiFePo4 battery to be 650 mAh.
Amps*seconds*minutes
0.00002*60*60
= 0.072 Ah
So one 650 mAh battery should last roughly 650/72 = 9 hours under constant load? That seems really low. Did I make an error?
