I said 200A because my kelly is capable of 200a but sure in the video i draw less than 200A
3p a123 26650 is way too low for the demand if you expect decent voltage sag.
the sag of A123 is due to the 1/IR per Ah of the A123... the lipo are better . The C rate of the A123 can be 30C and the nanotech be 20C, they are both determined differently due to the different operating range of the A123 and the lipo...
lipo: 3.7 nom 3,0V min delta is 0.7V
A123: 3.3 nom 2.0 min delta is 1.3V
this mean that for the same IR and C rate and Ah , the A123 will sag twice
