The Deans connector is rated for highter amperage than the Sermos. I fly big R/C helis and no one uses Sermos anymore...they melt over 50A. Everyone uses Deans. They are good up to about 100A.
4mm bullets are good too...just no polarity protection.
The attached pic is my 30 size electric heli. I get 80A spikes on my data logger. I use Deans.
