Connectors
 

Hello have a thunder power charger with the dc wires with the crocodile clips coming out of the side. I am looking to tidy things up a little as I use the AC connections most of the time , if I put a female 4mm panel connectors in side of charger what amp rating would I require, obviously I am using a 12 volt caravan battery now and again thanks for any advise would be much appreciated .
