I would recommend also comparing the voltage ripple values. It will give you a better idea of how much you're "stressing" the controller and batteries due to the batteries amperage output capabilities.

Here's a link to a post by Patrick on ripple voltage: http://www.rc-monster.com/forum/show...2&postcount=11

It explains what it is and acceptable ranges. Being that you're around 32 volts, anything below 2.2V is good, 2.3 - 3.2V is okay, 3.2-3.8V is marginal and somewhat risky, and anything above 3.8V could potentially damage the batteries and/or the ESC.

P.s: I forgot to tell/ask this CC staff yesterday...on ur site i think u got a word writen wrong... It says "Are u looking for something specfic?" Should it be "specific"? Just ignore if i am wrong... as English is not my language =)

haha yea, that should be specific, I'll let the webmaster know on Monday so he can get that fixed.

I checked the ripple on the log and the Max during that session was 2.26. I just noticed though that with all the data parameters being logged the XL only logs 8 minutes of data (must be a memory capacity thing). I would like to try and capture the entire run so i can see how the pack behaves at closer to LVC (25.6V). Thomas, would you say that the "Ripple" is the most important data to monitor regarding a batteries ability to supply the required current?
