Tell me if my calculations are correct.
(20) Tenergy D Cell 10,000 mAh batteries
price= $200
Volts= 24 Volt
Ah= 20 Ah (this one I'm not sure of, take 10,000/1000=10/10=1*20= 20Ah **********???)
(30) Energizer D Cell 2500 mAh batteries
price= $107.10
volts= 36 Volt
Ah= 7.5 Ah (not sure about this either, take 2500/1000=2.5/10=0.25*30= 7.25 Ah **********?)
