There is also the amp=draw profile to consider...do you draw 3000W for a few seconds, and then cruise along at 300W for several minutes to allow everything to cool down? or...do you apply 3000W continuously?
Higher volts can have a spark jump through the air a farther distance, and the XT90 has been used with apparent success in 24S system (a nominal 88V, peak 100V fully charged). Voltage shouldn't be an issue, so...lets focus on the amps.
Try them out on your user-profile, and if they get too hot to touch, I would recommend upgrading to a larger connector. The AS150's seem to be well-regarded (Anti Spark, 150A).
Regardless of what the web-catalog might say, I would not use these at 90A continuous, and...I actually use them, and like them.
Ahhh okay now I'm starting to understand -thanks for clearing things up. Yes my controller only does the peak 90a for 10sec max, the back down to cruising speed. I have a temperature gauge and Cycle analyst and will conduct some tests.
I contacted hobbyking and they also said voltage at these levels dont matter and XT90 with 6 awg should be fine with my batterybloc modular setup- have a bunch of series XT90 adaptors (parallel ones for balance charging). Only thing they said is it would have a hard time soldering 6 awg to XT90's
