A chisel tipped iron at about 700F and rosin core solder is the ticket. Regular lead-free solder has a way too high melting point and makes it very challenging to solder.
I don't know where on the planet you're located, but if you absolutely want the ez-solders and you're in the US, you can find them here:
All the positive comments on this type of connector, and you still need to buy accessories to make them easy to solder to! In any case, a quality soldering iron such as the temperature regulated Weller 100 watt iron makes soldering these types of connectors a couple second project. Trying to solder Deans and similar connectors with a unregulated 30 watt soldering iron is a lesson in frustration. This type of soldering iron is either to hot, or not hot enough.
As for me, those APP connectors work nicely, just crimp their terminals to the wire, and you're done. If you really need high current, those EC5 connectors will handle a LOT of current.
