If you had an application where you would expect max constant draw not to exceed 100-120 amps what battery would you get considering that you would run them in parallel for a total of 10,000 Mah and 18.5V?

All prices shipped for a set of 4.

1) Turnigy 5000mAh 5S 20C Lipo Pack = $215
2) ZIPPY Flightmax 5000mAh 5S1P 40C = $353
3) Hyperion 5s 4200 35C = $380

Even the 20C should theoretically handle the draw no problems as it would only be 10C but.....
Any thoughts, do you think 20C will be enough for the task at hand?

Not an electrical engineer here - but from everything that I have read on here and a couple of other sites ... when it comes to boats the higher the c rating the better!

I'm sure more knowledgeable guys will chime in on this!

my preference would be the hyperion for better quality, but all should be able to provide the amps you need. even at 20c that should give at least 30c burst for 20 seconds. 150 amps
