Re: Payload Power Sources
Great Plains Super Launch Mar 27, 2020 | 13:42 pmJoe,You're just reading or interpreting the curves the wrong way. The X or horizontal axis is A-H, not run time.The greater the current, the lower the A-H time. So in your example of .5 amp versus 1 amp, the .5[…]

Re: Payload Power Sources
Great Plains Super Launch Mar 27, 2020 | 13:20 pmThe discharge capacity in Ah changes a little, due to internal I2R losses, so you get a bit more Ah from lower currents vs higher currents. That's also why the voltage is a bit lower. It's not showing you the[…]

Re: Payload Power Sources
Great Plains Super Launch Mar 27, 2020 | 13:13 pmJoe,The graph that you have shared has the horizontal axis in units of Ah (Ampere*hours) not in hours. It is fine.This means that all current draws are about 7.5 Amp hours with the smaller draws performing better than the large[…]

Payload Power Sources
Great Plains Super Launch Mar 27, 2020 | 13:02 pmI am very confused on a battery pack. Say you have a pack that can run 1 amp of current draw for 10 hours. One would think that if you only drew 0.5 amps that it should run for 20[…]

Great Plains Super Launch Mar 23, 2020 | 13:19 pmThis conversation reminds me of some work my students did several years ago. Attached are a few slides from our presentation at the 2013 GPSL in Pella.That work was inspired by Ron K6RPT's long duration floaters and relates to Joe[…]
