Remember, those are spikes that last milli-seconds. It's all about duty cycle. If you are pulling 160A for 100ms every 10 seconds (1%), and then 15A for the remaining 9.9s, that equates to 16.45A average. Most electronics/switches/etc have a burst duty cycle that they can run. As long as you stay within that range, all is well. Unfortunately, Deans do not publish that level of data so it's hard to tell, but they say their connectors have less resistance that equal length of wire, so you should be fine.
