<p>Hi rickg1,</p><p>it's hard to tell battery capacity this way. the test I've made was for the highest amp discharge test. for battery capacity, i would need to make another video testing that whether the battery really hold 38Ah or it's a joke. and to achieve that i would make electronics dummy load to have fixed current drawn out of battery. say fixed Load=12A, then 38Ah / 12. result would be battery should survive for at least 3 hours under continuous load. you just give me an idea for my next video :)</p><p>hope this helps</p><p>Regards,</p><p>Hassan Al-Mahmoud</p>
