I'm looking for an easy and reliable way of connecting battery chargers to a lawn tractor and a mini tractor battery. The standard crocodile clips that come with the chargers are unreliable, go rusty and are too easy to touch on the wrong place.
I'm quite happy to drill some holes etc. in the tractors and I am also quite happy to do some soldering etc. Requirements are pretty obvious really:- Reasonable current capacity, say 10 amps or so maximum. Weather resistant in the sense of not corroding. Polarised by some means or other. Reasonably compact. Would prefer if they will simply pull apart (we all occasionally forget the charger is connected!).
I've hunted around on the CPC/Farnell site and a couple of other places but haven't found anything really suitable. The best I've found so far are the DIN loudspeaker connectors but I'm not really convinced that they can carry the current.
